ACRS Member: "How far is the nearest point in
Massachusetts from the plant?"

ACRS Member: "If you had an emergency zone of 2
miles 690 feet you would be in the clear?"

PSNH: "I think the answer to that question is
yes.

"

ACRS full committee meeting

ACRS: "The two reports that we have looked at have
both been reviewed by an outside, independent group
of experts in each case, and these experts
concurred with the results of the findings.
However, when we asked in terms of the containment,
I questioned why there wasn't a containment expert
on the independent review groups, and they pointed
out that the staff, NRC staff, through a contract
with Brookhaven National Laboratory, is reviewing
that aspect. So it will be reviewed."

ACRS: "I would hope the (NRC) staff develops some
kind of safety philosophy, if it hasn't, that it
uses to guide itself in decisionmaking concerning
these matters. ... I'm speaking for myself but let
me strongly suggest that you try to develop some,
what I'll call general philosophy in this regard,
and then some, what you might call generic
quantitative guidelines, before trying to make an
ad hoc decision on a specific case."

ACRS: "But let's face it. They wouldn't be
reviewing this PRA at this time if they didn't
think there was something like a change in the
prior guidelines for emergency planning in the
wind. Otherwise, I would like them to tell me why
they are taking time away from other tasks like
finding out how good a mark 2 containment is,
etc.?"

NRC 9-29-86 RESPONSE
TO SUBCOMMITTEE

Has the Commission staff ever advised PSNH concerning the studies it would deem appropriate for Justifying a reduction of the EPZ? If so, please provide all details of such discussions.

ANSWER.

In the recent past there have been some discussions of risk and emergency preparedness between management of PSNH and Robert Bernero, Director of BWR Licensing at NRC. Prior to taking his present position in November 1985, Mr. Bernero was in NRC's Office of Research and at NRR in positions involved in risk analysis, source term research, and regulatory utilization of such information. In those positions Mr. Bernero gave many public statements about the regulatory process including the reassessment of emergency preparedness requirements. Mr. Bernero did discuss such issues with Mr. William Derrickson and others of PSNH on (two) occasions. These were informal meetings which took place in Mr. Bernero's office. One took place on July 30, 1985, and Mr. Bernero recalls the other one as being a few months later.

In the time period following January 1, 1985, there were management
meetings, formal meetings, and telecons with the NRC staff with respect
to the Emergency Planning Zone for Seabrook Station. However, because
formal or personal notes are not available for all meetings or telecons,
to the best of our knowledge, we cannot provide you with a detailed
chronology, or identify of all meeting participants or cover with any
specificity all topics of discussion. However, based on available
notes and recollections of these meetings available at this time, we
believe the above chronology addresses your question.
