Fukushima Should Have Served as Wake-Up Call for U.S. Nuclear Regulatory Commission
On March 11, 2011, a 9.0-magnitude earthquake and 50-foot tsunami triggered meltdowns at three of six nuclear reactors at the Fukushima Daiichi plant in Japan. It was the one of the worst accidents in the nuclear industry's 60-year history, contaminating thousands of square miles, displacing more than 150,000 people and costing Japanese taxpayers nearly $100 billion.
The disaster was a wake-up call for the U.S. Nuclear Regulatory Commission (NRC). After all, nearly a third of the 104 U.S. reactors operating at the time were General Electric Mark I or Mark II reactors, the same as those in Fukushima. The accident raised an obvious question: How vulnerable are those reactors—and the rest of the U.S. fleet for that matter—to comparable natural disasters?
The NRC set up a task force to analyze what happened at Fukushima and assess how to make U.S. reactors safer. In July 2011, the task force offered a dozen recommendations to help safeguard U.S. nuclear plants in the event of a Fukushima-scale accident.
Unfortunately, the NRC has since rejected or significantly weakened many of those recommendations and has yet to fully implement the reforms it did adopt, according to a new Union of Concerned Scientists (UCS) report. UCS also found that the agency abdicated its responsibility as the nation's nuclear watchdog by allowing the industry to routinely rely on voluntary guidelines, which are, by their very nature, unenforceable.
"Although the NRC and the nuclear industry have devoted considerable resources to address the post-Fukushima task force recommendations, they haven't done all they should to protect the public from a similar disaster," said report author Edwin Lyman, a UCS senior scientist and co-author of the 2014 book, Fukushima: The Story of a Nuclear Disaster. "If the NRC is serious about protecting the public and plant workers, it should reconsider a number of recommendations it scrapped under pressure from the industry and its supporters in Congress."
The post-Fukushima task force's top priority was overhauling what it called a "patchwork" of NRC regulations and industry voluntary guidelines for "beyond-design-basis" events—incidents that plants were not designed to withstand. The task force argued that both regulators and plant owners would benefit from a coherent set of standards that would guard against severe events like Fukushima and provide a framework for implementing its other recommendations. After several years of deliberation, however, the NRC ultimately passed on making any fundamental changes, maintaining that its regulatory framework doesn't need fixing.
Lyman said this was a critical mistake. "By rejecting the task force's top recommendation," he said, "the NRC regulatory regime will remain full of holes, leaving the public at risk from potential accident scenarios that regulators may overlook."
The NRC then relied heavily on its vaguely worded "backfit" rule to reject many of the other recommended post-Fukushima safety upgrades. The rule limits the agency's ability to require new safety rules if a proposed upgrade's cost is deemed to exceed its benefits. Many important safety recommendations failed to pass this test, despite the fact that they would have made plants safer.
"The post-Fukushima, lessons-learned process provided the NRC a golden opportunity to reform its inconsistent approach to regulating the industry," Lyman said. "Unfortunately, it didn't take advantage of it."
Letting the Industry Make the Rules
The NRC and the nuclear industry's main response to the Fukushima accident is what they call the "diverse and flexible coping capability" program or FLEX for short, which will provide extra backup emergency equipment to cool reactors and spent fuel pools during a prolonged power loss.
The FLEX program is a prime example of the industry jumping out ahead of the NRC. In this case, the industry purchased backup emergency equipment—pumps, compressors, generators, batteries and the like—before the NRC had the chance to develop guidelines for the program. To cut costs, the industry bought commercially available equipment that may not weather a severe accident and the industry-initiated FLEX guidelines hinge on ambiguously worded, hard-to-enforce directives that, for example, mandate "reasonable protection" of safety equipment. Regardless, the NRC largely approved the industry's plan instead of developing its own standards.

Likewise, the NRC decided to continue to allow plant owners to develop their own voluntary plans for managing a core-melt accident, rejecting a task force recommendation to require them to do so. If plans are voluntary, the NRC has no authority to review them or issue citations when they are deficient.
"Once again, the NRC is ignoring a key lesson of the Fukushima accident: Emergency plans are not worth the paper they are printed on unless they are rigorously developed, maintained, periodically tested and subject to NRC inspection and enforcement," said Lyman. "When it comes to many critical safety measures, the NRC is allowing the industry to regulate itself."
Saying No to Filtered Vents
When three of the six Fukushima Daiichi reactors overheated, plant workers scrambled to lower reactor core pressure by depressurizing the containment building so they could inject cooling water. They couldn't open the containment vents from the control room, however, because there was no electric power. Without enough cooling water, the reactors melted down.
To avoid the possibility of this happening at the 30 currently operating U.S. reactors that share the same containment design as those at Fukushima, the NRC staff recommended that the agency not only require plant owners to install reliable, "hardened" vents that could be easily opened during an electricity outage, but also compel owners to add filters to avoid releasing radioactive material into the surrounding community. Four countries with the same type of GE reactors—Finland, Germany, Sweden and Switzerland—require filtered vents and Japan is planning to do so.
The nuclear industry, however, argued that the FLEX program obviated the need for filtered vents, despite the fact that filters would be more dependable than relying on plant workers to perform complex tasks under very trying circumstances. After years of analysis, the NRC staff reversed its original recommendation, asserting that that neither vent filters nor the industry's proposed alternatives were justified. Last August, NRC commissioners voted to do nothing.
"As a result," the UCS report states, "in the event of a severe accident, the NRC is leaving plant operators with a horrible dilemma: ... open the vents and deliberately release radioactivity into the environment or ... allow the reactor containment to overpressurize and potentially rupture, resulting in an even greater release of radiation."
Either way, we're talking about contaminating a vast area with high levels of radioactivity and increasing the cancer risk for nearby residents.
NRC Should Reconsider Safety Recommendations
The UCS report pulls back the curtain on a post-Fukushima reform process that has largely played out behind the scenes. Hopefully its findings will raise some eyebrows—if not sound the alarm—on Capitol Hill and in the Obama administration, because public safety depends on federal oversight. Elected officials should insist that the NRC reconsider the safety measures it rejected, especially replacing its hodge-podge of vaguely written rules and voluntary guidelines with a rational regulatory approach and establishing a transparent process that allows the public to assess the effectiveness of its reforms.
"The NRC and the nuclear industry have taken steps to address some of the safety vulnerabilities revealed by the Fukushima disaster," said Lyman. "But so far, the agency has failed to fully learn the lessons of Fukushima. It needs to go back to the drawing board and reconsider critical safety recommendations that it dismissed without good justification. And let me stress: This is not an academic exercise. The health and safety of more than 100 million Americans who live within 50 miles of a nuclear plant hang in the balance."

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.
theDOCK aims to innovate the Israeli maritime sector. Pexels<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported.

The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>

"As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>
