NRC Cherry-Picking in the Post-Fukushima Era: A Case Study

Mark Leyse , UCS

In the late 1960s, the Atomic Energy Commission (AEC), the forerunner of the NRC, paid the very companies that designed nuclear reactors—Westinghouse and General Electric (GE)—to test the efficacy of their own emergency cooling systems. Read More

What Does North Korea Want—and What is the US Prepared to Give?

, co-director and senior scientist

North Korea is not likely to negotiate in earnest unless it is convinced the United States is committed to the process. It is important that the administration put together a package of what it is willing to put on the table in response to Pyongyang’s steps. Read more >

What Does the US Want from North Korea?

, co-director and senior scientist

President Trump is planning to meet with North Korean leader Kim Jong-Un in May or June. In preparing for the summit, the administration must be clear about what it wants from the process—both near-term and long-term. And it needs to figure out what it is willing to put on the table to get those things. Read more >

The “Race” to Resolve the Boiling Water Reactor Safety Limit Problem

, director, Nuclear Safety Project

General Electric (GE) informed the Nuclear Regulatory Commission (NRC) in March 2005 that its computer analyses of a depressurization event for boiling water reactors (BWRs) non-conservatively assumed the transient would be terminated by the automatic trips of the main turbine and reactor on high water level in the reactor vessel. GE’s updated computer studies revealed that one of four BWR safety limits could be violated before another automatic response terminated the event.

Over the ensuring decade-plus, owners of 28 of the 34 BWRs operating in the US applied for and received the NRC’s permission to fix the problem. But it’s not clear why the NRC allowed this known safety problem, which could allow nuclear fuel to become damaged, to linger for so long or why the other six BWRs have yet to resolve the problem. UCS has asked the NRC’s Inspector General to look into why and how the NRC tolerated this safety problem affecting so many reactors for so long. Read more >
