Benny Hill Explains the NRC Approach to Nuclear Safety

, director, Nuclear Safety Project

The Nuclear Regulatory Commission’s safety regulations require that nuclear reactors be designed to protect the public from postulated accidents, such as the rupture of pipes that would limit the flow of cooling water to the reactor. These regulations include General Design Criteria 34 and 35 in Appendix A to 10 CFR Part 50.

Emergency diesel generators (EDGs) are important safety systems since they provide electricity to emergency equipment if outside power is cut off to the plant—another postulated accident. This electricity, for example, would allow pumps to continue to send cooling water to the reactor vessel to prevent overheating damage to the core. So the NRC has requirements that limit how long a reactor can continue operating without one of its two EDGs under different conditions. The shortest period is 3 days while the longest period is 14 days. Read more >

Nuclear Renaissance–Nuclear Requiem

, director, Nuclear Safety Project

There was considerable discussion a decade or so ago about the purported Nuclear Renaissance. New reactors were proposed almost everywhere but Delaware: Florida, Georgia, Alabama, North Carolina, South Carolina, Virginia, Louisiana, Texas, New Jersey, Pennsylvania, and Michigan. Read more >

Nuclear Plant Emergency Preparedness: Failure to Communicate

, director, Nuclear Safety Project

Disaster by Design/ Safety by Intent #36

Disaster by Design

Nuclear plant owners are required to develop plans for responding to accidents that describe actions to be taken by workers onsite as well as describing communications to local, state, and federal organizations so they can taken actions offsite. Among other things, the emergency plans detail when to activate the sirens that warn people in the community about an accident at the plant. Read more >
