Sixty-Plus Years of Reactor Safety Advice — and Still Going Strong
Ed Hackett
Executive Director
Advisory Committee on Reactor Safeguards
For as long as the United States has worked on commercial nuclear
power plants, a group of experts has given regulators independent safety
advice. Since Congress passed the Atomic Energy Act of 1954, the
group’s been called the
Advisory Committee on Reactor Safeguards.
The committee’s dozen or so members contribute decades of academic
and/or practical experience in their specialties, which include risk
assessment, health physics, accident analysis and several types of
engineering. Past and present committee members have also lent their
expertise to international regulators.

Members of the ACRS brief the NRC Commission.
When there’s an opening on the committee, the Commission chooses a
replacement from nominees among the leading experts in a given
specialty. Committee members are supported by a small group of NRC staff
who focus solely on the committee’s independent activities.
The full committee meets 10 times a year, spending several days each
time to discuss a broad range of topics. For instance, this month’s
meeting agenda included a developing new rule related to safety
enhancements based on lessons learned from the Fukushima nuclear
accident. Other meetings have covered reviews of new reactor licensing
topics and operating reactor license renewal, as well as proposed
facilities to create radioactive material for medical uses.
Committee members ask detailed questions of both NRC staff and
industry representatives. If members feel an issue needs more
explanation or analysis, they’ll keep asking questions and challenging
assumptions until they’re satisfied. All of this interaction contributes
to the committee’s opinions on the topics.
The committee’s conclusions, which are independent of the NRC staff’s work, are provided in formal
letters
to the NRC’s Chairman. The Commission takes the committee’s views into
account when it considers licensing or policy matters. The committee
also meets publicly with the Commission at least once a year to discuss
major topics. The Commission uses the advice provided by the committee,
in addition to the information provided by the NRC staff, in reaching
its decisions on regulatory matters.
The committee also has an obligation to advise the U.S. Navy on its
nuclear reactor program, as well as the Defense Nuclear Safety Board,
which deals with Department of Energy-controlled facilities.
The committee does all of this work according to the requirements of the
Federal Advisory Committee Act.
This means all committee meetings are public, except when discussing
sensitive information the NRC needs to protect. It also means the public
can speak and present information to the committee. Keep an eye on our
schedule to see when we’ll discuss something you’re interested in. Also, see our
