20515 Dear Congressman Erte'-
In my letter to you of !iarch 15, 1979 I promised to provide you with infonnation concerning the impact of the shutdown of 16 nuclear power reactors on the installed reserve margins of potentially affected utilities.
The 16 plants were identified in a press release of the Union of Concerned Scientists (UCS) as those that UCS felt should be shutdo'.ri.
The impact on reliability council installed reserve margins of losing the output on the Ib nuclear power plants is indicated in the attach-ments to this letter prepared by the NRC Office of Nuclear Reactor Regulation; these data are based upon the April 1,1979 submission of the country's electric reliateility councils to DOE.
The first attach-ment lists 12 stations (16 reactors), their component units, design electrical ratings by unit, and the reliability council within which the station is located.
The second attachment is a map indicating the geographic boundaries of the nation's electric reliability council areas.
Attachment three is a table indicating the National Electric Reliability Council's April 1st estimate of dependable capacity, peak demand, and the resulting installed reserve margin.
Information in the table applies to the summer and winter peaks of 1979 and 1979/80 respectively.
The three columns on the right indicate the impact on dependable capability and installed reserve margin of removing the 16 plants from operation.
Of course, scheduled maintenance and unforeseen outages will lower the operating (i.e., actual) reserves.
Attachment three indicates that for both the summer and winter peaks--
for the years indicated--a decrease in the installea reserve margin would occur nationally as a result of closing the 16 stations. The ducrease wou'.d be more severe for both winter and summer ceaks in the following council areas:
MAAC, NPCC (New England), TVA, and VACAR.
It is important to note that these figures do not take conservation into account.
Conservation should be considered in any effort to assess the real impacts of closing down particular plants.
The najor impact would be in VACAR where the installed reserve margin would fall to 45 for the sumer peak.

The 'onorable Alan Ertel I hope that this information is responsive to your request.
If we can be of further assistance, please feel free to call upon us.

Dear Chairman Hendrie:
We are taking this opportunity to bring to your attention a matter of serious concern to us and to our constituents.
The controversy over nuclear power has escalated in recent weeks in the wake of the Commission's repudiation of major parts of the Rasmussen study.
As we understand it, the Coa--
mission had relied on the accident probabilities contained in the study to support the continued operation of several power plants whose safety systems are possibly questionable.
Even though the study is no longer considered entirely author-itative by the Commission, the NRC has yet to indicate what the next step will be.
Both the Congress and the public have received information from the Union of Concerned Scientists, who advocate not only the shutdown of the 16 plants in ques-tion, but also a moratorium on the licensing and construction of nuclear power plants.
Now, weeks after the release of the Lewis study, which raised the doubts about the Rasmussen report and opened a Pandora's box of questions about NRC's safety policies and procedures in general, the Commission has not offered any assessment of the risks of continued operation of these particular power plants, nor has it offered any specific indication of how it plans to proceed without the Rasmussen report.
There are several crucial questions which mst be addressed now:
--What does the NRC plan with respect to the continued opera-tion of the 16 power plants in questinn?
--What risks are we encountering that we did not know about prior to the Lewis study?
--What consequences would a shutdown of any of these plants have on the supply of energy to the affected area?

CHAIRMAN JOSEPH M.
HENDRIE February 9, 1979 page 2
--How will the NRC deal with the types of safety issues raised by the Lewis study and what, if any, inproved safety precau-tions are needed in existing power plants?
Continued delay ir confronting these matters can only further damage the cause of nuclear power development in the United States, at an all too critical point in the nation's energy future.
The uncertainties of this future, characterized now by the crisis in Iran and the dwindling of our conventional fuel supplies, necessitate that these issues be resolved.
We appreicate your prompt attention to this matter.
Sfqcerely
