Nuclear nightmare threat from "dirty" radioactive dispersion bomb needs urgent attention


On Friday last week (29th March) in Liverpool I attended my first meeting as an appointed expert on the Independent Advisory Panel for the UK Chief Nuclear Inspector of the UK nuclear regulator, the Office for Nuclear Regulation (ONR). (http://news.onr.org.uk/2019/04/chief-nuclear-inspectors-independent-advisory-panel/)

IAP members have been invited to nominate issues or themes to be considered at the next meeting in the autumn, and I came away thinking nuclear security - and how it can be discussed meaningfully with politicians and the public - is an important and under-addressed matter that the IAP could engage.

No sooner had I started to think how best this might be considered than ONR’s United States equivalent, the US Nuclear Regulatory Commission, came under fire from another US Governmental body - the Government Accountability Office – in a hard-hitting, and frankly very disturbing report, on how a radioactive ‘dirty bomb’ (or as it is more technically calleda Radiation Dispersal Device [RDD])could  be made from materials secreted out of US commercial nuclear facilities (‘Combating Nuclear Terrorism: NRC Needs to Take Additional Actions to Ensure the Security of High-Risk Radioactive Material,’  https://www.gao.gov/mobile/products/GAO-19-468)

This is GAO’s own description of why they undertook the study:

 

“NRC is responsible for regulating the security of radioactive material in the U.S. Failure to secure this material could result in an RDD causing socioeconomic damage. The Consolidated and Further Continuing Appropriations Act, 2015 (Public Law 113-235) includes a provision for GAO to review NRC’s security requirements for high-risk radioactive material. This report examines, among other things, (1) the extent to which radioactive security experts agreed that NRC’s assessment of risk includes all relevant criteria, and (2) NRC’s 2016 evaluation of its security requirements for high-risk radioactive material. GAO reviewed NRC policies and procedures, worked with the National Academies of Sciences to convene a meeting with 18 experts in radioactive security, and reviewed 3 recent Sandia studies. GAO used the views of security experts to define high risk, and they generally agreed that high risk includes both larger and some smaller quantities of radioactive materials”.

 

What GAO Found

 

The report records:

The 18 experts at a meeting GAO convened with the National Academies of Sciences generally agreed that the Nuclear Regulatory Commission (NRC) assessment of risks of radioactive material does not include all relevant criteria. NRC limits its criteria to prompt fatalities and deterministic health effects from radiation, which, according to the experts and recent studies, are unlikely to result from a radiological dispersal device (RDD). Two studies from Sandia National Laboratories (Sandia) measuring consequences of RDDs, released in 2017 and 2018, found that there would be no immediate fatalities from radiation. The experts at the meeting generally agreed that socioeconomic effects (e.g., relocations and clean-up costs) and fatalities that could result from evacuations are the most relevant criteria for evaluating the risks of radioactive material. The two Sandia studies found that a large RDD could cause about $30 billion in damage and 1,500 fatalities from the evacuation, and a considerably smaller RDD could cause $24 billion in damage and 800 fatalities from the evacuation. By considering socioeconomic impacts and fatalities resulting from evacuations in its criteria, NRC would have better assurance it was considering the more likely and more significant consequences of an RDD.

NRC’s 2016 report evaluating its security requirements for high-risk radioactive material, required by Public Law 113-235, considered only the security of larger quantities of such material and not smaller quantities. Experts who attended GAO’s meeting stated, and two 2018 Sandia studies agree, that if smaller quantities of certain radioactive material were used in an RDD, the impacts would be comparable to an RDD with a considerably larger amount of such material. For example, a 2018 study from Sandia found that malicious use of certain radioactive materials in smaller quantities could cause significant socioeconomic consequences. By requiring additional security measures for these smaller quantities of high-risk material, NRC can have better assurance that its security requirements are sufficient to secure all high-risk radioactive material from theft and use in an RDD.”

 

GAO Recommended three key actions:

“GAO is making three recommendations to NRC, including that it consider socioeconomic consequences and fatalities from evacuations as criteria for determining security measures and require additional security measures for smaller quantities of high-risk material.

NRC “generally disagreed” with the recommendations, stating that GAO’s evidence “does not provide a sufficient basis for recommended changes.”

But GAO observed it “continues to believe these recommendations are important.

I think the UK ONR now  needs to either undertake, or commission - as a matter of urgency - a similar study to the one  recently released  by the GAO in the US.

 

BACKSTORY

[UK]Chief Nuclear Inspector’s Independent Advisory Panel

ONR, 4 April 2019


Our work is wide-ranging and technically complex and we’re committed to engaging with nuclear topic experts to ensure that we have access to relevant information to inform our regulatory strategies and approaches.

In 2016, we introduced the Chief Nuclear Inspector’s Independent Advisory Panel (IAP) to provide independent advice to ONR on nuclear matters.

The IAP is now well established and meets twice a year, bringing together experts from across the nuclear industry, academic community, government departments and other regulators who contribute to informed debate and provide advice on relevant topics. Their discussions range from regulatory strategies and policy to implications of developments in new nuclear technologies and the regulation of innovation, and we’re always interested to hear their views.

To increase diversity of views and strengthen ONR’s openness and transparency, the panel recently welcomed two new members from the Non-Government Organisations (NGO) community.

Peter Burt and Dr David Lowry joined the 15-strong panel at the latest meeting on 29 March in Liverpool, where they contributed to discussions on ONR’s organisation effectiveness indicators, challenges of supply chain regulation and some of our strategic improvement projects.

Appointed for three years, both members bring a wealth of new experiences, skills and views to the panel’s vitally important discussions. They have a broad understanding of the nuclear industry and the hazards it presents, along with knowledge of the current and future nuclear landscape, strengthening the panel to ensure that we have a range of opinions and a high level of intelligence.


Mark Foy, Chief Nuclear Inspector for ONR said; “The panel helps us to maintain our approach to seeking independent advice and guidance to help inform our future regulatory strategy and approaches.

“We are committed to being an open and transparent regulator so inviting representatives from the NGO community on to the panel was the natural thing to do. I’m pleased that both David and Peter have joined the panel, it is clear from the first meeting that they will bring a wealth of knowledge and experience and I look forward to their further contributions.”

 

 

U.S. nuclear regulators do not recognize real danger of dirty bombs, watchdog says

Besides killing people with radiation, a dirty bomb would spread panic, prompt evacuations, require cleanup and undermine the economy, says a new report.

By Dan De Luce

WASHINGTON — The Nuclear Regulatory Commission is failing to recognize the full range of dangers posed by a potential dirty bomb attack and needs to take more action to secure high-risk radioactive material, according to a government watchdog report released Thursday.

In assessing the possible effect of a radioactive dirty bomb detonated in an American city, the U.S. nuclear regulator has only focused on the possible health effects caused by the spread of radiation, the Government Accountability Office report said. But the NRC has not taken into account the potential consequences of a panic-driven evacuation and costly decontamination effort, according to the report.

"NRC's regulatory approach in many ways is based on the idea that a dirty bomb would not be a high consequence event," said David Trimble, director of the National Resources and Environment office at the GAO.

"Their view of what the risk is is very circumscribed, it's very narrow."

A dirty bomb uses a conventional explosive combined with radioactive material to spread radiation over a wider area, and some terrorist groups have sought to construct such a device over the years.

Rather than deaths or harm caused by radiation, the most significant impact of a radioactive dirty bomb would be its disruptive effect, by spreading panic, prompting evacuations, requiring cleanup work and undermining economic activity, said the report, citing experts convened by the National Academy of Sciences as well as other studies.

A chaotic evacuation could cause more deaths than any radiation released in an attack, and the results of the disruption and contamination could cause billions of dollars in damage, the report said.

"Few deaths would occur due to the radioactive nature of the event," the report said. "However, significant social and economic impacts could result from public panic, decontamination costs, and the denial of access to infrastructure and property for extended periods of time."

The report cited the 2011 meltdown of the Fukushima Daiichi nuclear plant after an earthquake and subsequent tsunami, saying more people died from the evacuation process than from radiation releases or the effects of the natural disasters.

The NRC's staff operates under guidelines that require it to only evaluate the risk of a dirty bomb based on immediate deaths and other health effects of the radiation released.

"If you're using that as a criteria to regulate, you're kind of missing the boat," Trimble said.

The GAO also urged the nuclear agency to take additional measures to safeguard smaller quantities of high-risk radioactive material, arguing that even smaller amounts could still have major consequences in a dirty bomb incident.

The Nuclear Regulatory Commission disagreed with most of the report's findings, saying the GAO's view was based on unlikely scenarios and selected opinions from experts.

"The security and appropriate control of radioactive materials is a top priority for the NRC," the agency said in a response to the GAO, which was included in an appendix to the report.

The GAO report was based in part on a meeting of 18 experts across a range of fields arranged with the NRC and the National Academies of Sciences. But in its letter, the NRC said the GAO had relied on "selected aspects of the panel discussion to form the primary basis for its recommendations" and referred to "statements of one or two panel members to draw overarching conclusions."

The nuclear regulator disagreed with the report's reference to the Fukushima example on evacuations, arguing it was no equivalent to a possible dirty bomb scenario. In Fukushima, the nuclear power plant meltdown was accompanied by an earthquake and tsunami, which complicated evacuation efforts, the NRC said.

The NRC also rejected a GAO recommendation to bolster security measures for certain quantities of a radioactive material, americium-241, stored in close proximity, saying it had already taken sufficient steps.

The NRC said it seeks "to balance the need for the protection of radioactive materials with their availability for beneficial uses in the medical, academic, and industrial environments."

The Nuclear Regulatory Commission has come under frequent criticism over the decades from lawmakers, environmental and watchdog groups that it is overly deferential to the nuclear industry. The NRC's supporters have rejected the criticism as an attempt to tarnish nuclear power as a viable energy source.

Over the past decade, the GAO has previously taken the NRC to task for how it oversees security measures for radioactive material. The NRC accepted the findings in those audits and took action to tighten rules for organizations licensed to use radioactive materials for commercial, medical or research purposes.

Combating Nuclear Terrorism:
NRC Needs to Take Additional Actions to Ensure the Security of High-Risk Radioactive Material


 

GAO-19-468, Publicly Released: Apr 4, 2019.

Fast Facts

In the hands of terrorists, radioactive material could be used for a dirty bomb. The Nuclear Regulatory Commission considers the health risks from short-term radiation exposure when determining how to safeguard radioactive material.

But experts told us factors such as deaths during an evacuation and the cost of environmental cleanup should also be considered.

We recommended, among other things, that the NRC consider these additional factors in determining security measures for radioactive material.

Why GAO Did This Study

NRC is responsible for regulating the security of radioactive material in the U.S. Failure to secure this material could result in an RDD causing socioeconomic damage. The Consolidated and Further Continuing Appropriations Act, 2015 (Public Law 113-235) includes a provision for GAO to review NRC's security requirements for high-risk radioactive material. This report examines, among other things, (1) the extent to which radioactive security experts agreed that NRC's assessment of risk includes all relevant criteria, and (2) NRC's 2016 evaluation of its security requirements for high-risk radioactive material. GAO reviewed NRC policies and procedures, worked with the National Academies of Sciences to convene a meeting with 18 experts in radioactive security, and reviewed 3 recent Sandia studies. GAO used the views of security experts to define high risk, and they generally agreed that high risk includes both larger and some smaller quantities of radioactive materials.

What GAO Recommends

GAO is making three recommendations to NRC, including that it consider socioeconomic consequences and fatalities from evacuations as criteria for determining security measures and require additional security measures for smaller quantities of high-risk material. NRC generally disagreed with the recommendations, stating that GAO's evidence does not provide a sufficient basis for recommended changes. GAO continues to believe these recommendations are important.
