Science May Be Objective But That Doesn't Mean That All Scientists Are Because of Their Drive to Push Their Institutions and Projects


             Earlier this summer, a group of Congressional representatives—led by Tim Bishop of Long Island—hosted a reception in East Hampton for a fellow congressman, Bill Foster of Illinois.
             An emphasis was on how Foster is one of only three scientists in the House of Representatives. His invitation to the fundraiser was headed with, “Why Don’t Americans Elect Scientists?”  Foster stated: “The complex economic and technological issues our nation faces today will require leaders who think through the critical issues of the day, using logic and facts rather than resorting to mindless party-line talking points...Part of that solution has to be to elect more scientists and engineers to Congress.”

A biography of Foster accompanying the invitation noted that for 22 years he worked at Fermilab and “participated in leading-edge scientific research, designed and built state-of-the-art physics experiments.” Fermilab in Illinois, with 1,750 employees, is operated by the U.S. Department of Energy.

Considering especially the debate among Congressional representatives on climate change, science is indeed important.  Foster is a Democrat, like Bishop of Southampton, and the other representatives who hosted him on June 28th, Steve Israel of Huntington on Long Island and Carolyn Maloney of Manhattan. Democrats in Congress, and Democratic President Barack Obama, have been blasting Republicans in Congress who deny climate change and global warming are happening. The science on climate change and global warming is clear, they emphasize.  They charge the GOPers have a politicized “anti-science” agenda.

Bishop’s Republican opponent this year, State Senator Lee Zeldin of Shirley, Long Island is holding his own fundraiser on September 8th with as his main guest former Representative Allen West of Florida, typical of those GOPers. “When asked if he felt that climate change was causing the Earth to become warmer, West responded with a firm ‘No,’” according to published reports.  West is a hero of the Tea Party in which climate change denial is strong.

Yes, utilizing science rather than a dubious political line when it comes to climate change and global warming is a good thing. But, on the other hand, scientists often also have their own political agendas rooted in promoting scientific institutions and their projects.  Science might be objective—but that doesn’t mean all scientists are.

Many of us are familiar with President Eisenhower’s warning in his farewell address to the nation in 1961 about the rise of a “military-industrial complex.” Not widely known is that the original draft of that speech warned not just of a “military-industrial complex” but of a “military-industrial-scientific complex.” The president’s science advisor, James Killian, later president of MIT, pleaded that the word “scientific” be eliminated, and it was. Nevertheless, President Eisenhower went on warning, “Today, the solitary inventor, tinkering in his shop, has been overshadowed by task forces of scientists and laboratories.” He declared that “in holding scientific research and discovery in respect…we must also be alert to the equal and opposing danger that public policy could itself become the captive of a scientific technological elite.”

David E. Lilienthal, first chairman of the U.S. Atomic Energy Commission (AEC), used similar words in his 1963 book Change, Hope, and the Bomb. He wrote how now “scientists are ranked in platoons” and ” the independent and humble search for new truths about nature has become confused with the bureaucratic impulse to justify expenses and see that next year’s budget is bigger than last’s.” He spoke about the “elaborate and even luxurious [national] laboratories that have grown up at Oak Ridge, Argonne, Brookhaven.”

In that line he was referring to Brookhaven National Laboratory (BNL) set up by AEC on a former Army base in Upton on Long Island and now operated by the U.S. Department of Energy.

One need only examine what happened to Bishop’s predecessor in the lst Congressional District, three-term Representative Michael Forbes of Quogue, Long Island in 1999 after he challenged BNL, to see the concerns of President Eisenhower and Mr. Lilienthal playing out. Mr. Forbes was concerned about radioactive leaks from nuclear reactors at BNL and spoke out forcefully. He was opposed in a primary for the Democratic nomination by Regina Seltzer of Bellport, Long Island whose husband had been a BNL scientist. BNL personnel manned phone banks for Seltzer. She took the nomination from Forbes by 45 votes, but lost the general election. Meanwhile, a highly capable representative was driven out of Congress.

There have been many studies into scientists being influenced by ties to government and corporations and perverting their analyses.

Being anti-science, as such, is wrong. But so is having an uncritical belief in scientists

Secret Diablo Canyon Report Revealed

            As aftershocks of the 6.0 Napa earthquake that occurred Sunday in California continued, the Associated Press this week revealed a secret government report pointing to major earthquake vulnerabilities at the Diablo Canyon nuclear plants which are a little more than 200 miles away and sitting amid a webwork of earthquake faults.

It’s apparent to any visitor to the stretch of California where the two Diablo Canyon plants are sited that it is geologically hot. A major tourist feature of the area: hot spas.     “Welcome to the Avila Hot Springs,” declares the website of one, noting how “historic Avila Hot Springs” was “discovered in 1907 by at the time unlucky oil drillers and established” as a “popular visitor-serving natural artesian mineral hot springs.” www.avilahotsprings.com


Nevertheless, Pacific Gas & Electric had no problem in 1965 picking the area along the California coast, north of Avila Beach, as a location for two nuclear plants.


It was known that the San Andreas Fault was inland 45 miles away. Then, in 1971, with construction underway, oil company geologists discovered another earthquake fault, the Hosgri Fault, just three miles out in the Pacific from the plant site and linked to the San Andreas Fault.


In 2008 yet another fault was discovered, the Shoreline Fault—but 650 yards from the Diablo Canyon plants.


The Shoreline Fault, and concerns about the vulnerability of nuclear plants to earthquakes in the wake of the 2011 Fukushima Daiichi disaster, are integral to a 42-page report written by Dr. Michael Peck, for five years the lead inspector on-site for the U.S. Nuclear Regulatory Commission at Diablo Canyon.


Peck’s report was obtained by the Associated Press, which has done excellent journalism in recent years investigating the dangers of nuclear power, and the AP issued a story Monday on the report.


Peck writes: “The new seismic information resulted in a condition outside of the bounds of the existing Diablo Canyon design basis and safety analysis. Continued reactor operation outside the bounds of the NRC approved safety analyses challenges the presumption of nuclear safety.”


He also states: “The Shoreline [Fault] Scenario results in SSC [acronym in the nuclear field for Structures, Systems and Components] seismic stress beyond the plant SSE [Safe Shutdown Earthquake] qualification basis. Exposure to higher levels of stress results in an increase[d] likelihood of a malfunction of SSCs. The change also increases the likelihood of a malfunction of SSCs important to safety...”


Peck notes that the “prevailing” NRC “staff view” is that “potential ground motions from the Shoreline fault are at or below those levels for which the plant was previously evaluated and demonstrated to have a ‘reasonable assurance of safety.’”  


He disagrees and says that the NRC staff “also failed to address the Los Osos and San Luis Bay faults,” faults that the Shoreline Fault are seen as potentially interacting with, and that “new seismic information” concludes that “these faults were also capable of producing ground motions”


Also, he says: “The prevailing staff view that ‘operability’ may be demonstrated independent of existing facility design basis and safety analyses requirements establishes a new industry precedent. Power reactor licensees may apply this precedent to other nonconforming and unanalyzed conditions.”


 “is that it comes from within the NRC itself, and gives a rare look at a dispute within the agency. At issue are whether the plant’s mechanical guts could survive a big jolt, and what yardsticks should be used to measure the ability of the equipment to withstand the potentially strong vibrations that could result.”    http://www.ktvu.com/news/news/ap-exclusive-expert-calls-diablo-canyon-shutdown/ng8Tj/


The AP story also says, “Environmentalists have long depicted Diablo Canyon—the state’s last nuclear plant after the 2013 closure of the San Onofre reactors in Southern California—as a nuclear catastrophe in waiting. In many ways, the history of the plant, located halfway between Los Angeles and San Francisco...and within 50 miles of 500,000 people, has been a costly fight against nature, involving questions and repairs connected to its design and structural strength.”


Calling the Peck report “explosive,” the environmental group Friends of the Earth this week described it as having been “kept secret for a year.”


Said Damon Moglen, senior strategy advisor at Friends of the Earth,
 "Inspector Peck is the canary in the coal mine, warning us of a possible catastrophe at Diablo Canyon before it’s too late. We agree with him that Diablo Canyon is vulnerable to earthquakes and must be shut down immediately.”


Moglen said: “Given the overwhelming risk of earthquakes, federal and state authorities would never allow nuclear reactors on this site now. Are PG&E and the NRC putting the industry’s profits before the health and safety of millions of Californians.”   


“Rather than the NRC keeping this a secret,” Moglen went on, “there must be a thorough investigation with public hearings to determine whether these reactors can operate safely.”


Peck is still with the NRC, a trainer at its Technical Training Center in Chattanooga, Tennessee.


Michael Mariotte, president of the Nuclear Information & Resource Service, commented Monday  http://safeenergy.org/2014/08/25/former-top-nrc-inspector-says-shut-diablo-canyon/
that in “plain English” what Peck’s report acknowledges is: “The NRC does not know whether Diablo Canyon could survive an earthquake, within the realm of the possible, at any of the faults around Diablo Canyon. And the reactors should shut down until the NRC does know one way or the other. Of course, if the reactors cannot survive a postulated earthquake, the obvious conclusion is that they must close permanently. The question is whether the NRC will ever act on Peck’s recommendation or whether the agency will continue to sit on it until after the next earthquake.”


Mariotte also says: “The irony is that this should have been the big news a year ago; Peck wrote his recommendation—in the form of a formal Differing Professional Opionion—in July 2013. And the NRC still hasn’t taken action or even responded to it.”


In his report Peck also states that the NRC is supposed to be committed to a “standard of safety” and “safety means avoiding undue risk or providing reasonable assurance of adequate protection for the public.”


Meanwhile, PG&E has not only been insisting that its Diablo Canyon plants are safe, despite the earthquake threat, but has filed with the NRC to extend the 40 year licenses given for their operations  another 20 years—to 2044 for Diablo Canyon 1 and to 2045 for Diablo Canyon 2.


An analysis    http://www.ccnr.org/crac.html   done in 1982 by Sandia National Laboratories for the NRC, titled “Calculations for Reactor Accident Consequences 2,” evaluated the impacts of a meltdown with “breach of containment” at every nuclear plant in the U.S.—what happened at the Fukushima Daiichi nuclear plants as a result of an earthquake. For the Diablo Canyon nuclear plants, it projected 10,000 “peak early fatalities” for each of the plants and $155 billion in property damages for Diablo Canyon 1 and $158 billion for Diablo Canyon 2—in 1980 dollars.

Solar Power as an Alternative to Dangerous Nuclear Power in Space

            A demonstration that in space as on Earth solar power is an alternative to dangerous nuclear power is to come this week when a solar-powered spacecraft called Rosetta will rendezvous with a comet at 375 million miles from the Sun.
            The Rosetta space probe, energized with solar power, is to meet up Wednesday with Comet 67P/Churyumov-Gerasimenko. It will begin making observations, relaying back to Earth high-resolution images and information from its sensors, of the two-and-a-half mile wide comet Rosetta will subsequently send a lander down to the comet that will drill into it and perform a variety of experiments. For a year, Rosetta will fly alongside the comet, named after the two Ukranian astronomers who discovered it in 1969.
            For decades, the United States and the Soviet Union, and now Russia, stressed the use of atomic energy as a source of power in space—and there have been accidents as a result.
The most serious were the falls back to Earth of a U.S. satellite with a SNAP-9A plutonium-238 radioisotope thermal generator on board in 1964, disintegrating as it fell, dispersing plutonium worldwide, and of the Soviet Cosmos Satellite 954 in 1978, with an atomic reactor on board, also breaking up, and spreading nuclear debris for hundreds of miles across the Northwest Territories of Canada.
The late Dr. John Gofman, professor of medical physics at the University of California at Berkeley, long connected the SNAP-9A accident and its dispersal of plutonium with a global increase in lung cancer.  Canada demanded compensation for the Cosmos-954 accident which the Soviet Union eventually paid, in part.
Now all satellites are solar-powered as is the International Space Station. But there has been a push to continue to use nuclear power on space probes with NASA and formerly Soviet and now Russian space authorities insisting that solar power cannot be harvested far from the Sun.
However, the European Space Agency declares on its website—http://www.esa.int/Our_Activities/Space_Science/Rosetta/Frequently_asked_questions —“The solar cells in Rosetta’s solar panels are based on a completely new technology, so-called Low-intensity Low Temperature Cells. Thanks to them, Rosetta is the first space mission to journey beyond the main asteroid belt relying solely on solar cells for power generation. Previous deep-space missions used nuclear RTGs, radioisotope thermal generators. The new solar cells allow Rosetta to operate over 800 million kilometres from the Sun, where levels of sunlight are only 4% those on Earth. The technology will be available for future deep-space, such as ESA’s upcoming Jupiter Icy Moons Explorer.”
            ESA notes: “ESA has not developed RTG i.e. nuclear technology, so the agency decided to develop solar cells that could fill the same function.”
Rosetta, launched in 2004, “relies entirely on the energy provided by its innovative solar panels for all onboard instruments and subsystems,” says ESA.
NASA has begun to follow ESA’s lead.  It went with solar power for its Juno mission to Jupiter that is now underway. Launched in 2011, energized by solar power, the Juno space probe is to arrive at Jupiter in 2016. 
At the distance at which Rosetta will encounter Comet 67P/Churyumov-Gerasimenko or at which Juno will be doing experiments involving Jupiter or ESA’s Jupiter Icy Moons Explorer will work, energy from the Sun is but a small fraction of what it is on Earth. Still, it can be effectively utilized.  (NASA’s last space probe mission to Jupiter, Galileo, launched in 1989, was plutonium-powered and NASA officials insisted, including in sworn testimony countering a challenge to Galileo in federal court, that this was the only energy choice. There were numerous protests against Galileo and have been to subsequent nuclear space shots led by the Global Network Against Weapons & Nuclear Power in Space (www.space4peace.org).
Rosetta is named after the Rosetta Stone, a slab of basalt found in Egypt in 1799 with inscriptions carved on it that enabled the deciphering of hieroglyphics, the ancient language of Egypt. “As a result of this breakthrough, scholars were able to piece together the history of a lost culture,” notes ESA.
Likewise, “Rosetta’s prime objective is to help understand the origin and evolution of the Solar System,” says ESA. “The comet’s composition reflects the composition of the pre-solar nebula out of which the Sun and the planets of the Solar System formed, more than 4.6 billion years ago. Therefore, an in-depth analysis of Comet 67P/Churyumov-Gerasimenko by Rosetta and its lander will provide essential information to understand how the Solar System formed.”
ESA adds, “There is convincing evidence that comets played a key role in the evolution of the planets, because cometary impacts are known to have been much more common in the early Solar System than today. Comets, for example, probably brought much of the water in today’s ocean. They could even have provided the complex organic molecules that may have played a crucial role in the evolution of life on Earth.”
Rosetta “will be undertaking several ‘firsts’ in space exploration,” says ESA. “It will be the first mission to orbit and land on a comet.” And, Rosetta will be “the first spacecraft to witness, at close proximity” the changes in a comet as it approaches the Sun. Rosetta’s lander “will obtain the first images from a comet’s surface and make the first in-situ subsurface analysis of its composition.”
The Rosetta lander, given the name Philea, is to touch down on the comet’s surface in November and “remain operational through the end of 2015....A drilling system will obtain samples down to 23 cm below the surface and will feed these to the spectrometers for analysis, such as to determine the chemical composition. Other instruments will measure properties such as near-surface strength, density, texture, porosity, ice phases and thermal properties...In addition, instruments on the lander will study how the comet changes during the day-night cycle, and while it approaches the Sun.”
The lander is being called Philea for Philea Island in the Nile where an obelisk was found that supplemented the use of the Rosetta Stone in the deciphering of hieroglyphics.
The cost of the mission is 1.3 billion Euros ($1.75 billion at current exchange rates) and ESA asks the question: “Why spend such a huge amount of public money on studying remote stones in space?”
 ESA responds: “ESA’s task is to explore the unknown. In the case of Rosetta, scientists will be learning about comets, objects that have fascinated mankind for millennia” and “are thought to be the most primitive objects in the Solar System, the building blocks from which the planets were made. So Rosetta will provide exciting new insights into how the planets, including Earth, were born and how life began.”
There can be things that can still go wrong on the mission. Gases from the comet could affect Rosetta flying with it. Philae could fail to get hooked to the comet, although a “harpoon” system has been devised for it to anchor itself to the comet’s surface.
But if the Rosetta mission is a success it will be a superb example of a space mission that represents no nuclear threat to life on Earth and of a quest with the highest of purposes—exploring the mysteries of the Solar System and the origins of life.
