November 29, 1979 Docket Nos. 50-295 and SD-304 Mr. Cordell Reed Assistant Vice President Conmonwealth Edison Company Post Office Box 767 Cnicago, Illinois 60690
Dear Mr. Reed:
In a recent discussion with you, we discussed certain aspects regarding the location of Zion Station Units 1 and 2 in areas of relatively high population density.
Specifically, we indicated that the staff was considering an in-depth review of that facility which would extend beyond the review currently in progress of your emergency preparedness capabilities.
Various alternatives would be considered that would be effective in reducing the probability and consequences of a severe reactor accident.
The NRC review will also include the Indian Point Station Unit No. 2 and Unit No. 3 facilities. As a first step in this activity, an initial joint meeting with the licensees of all of these facilities is scheduled for December 5, 1979, at 10:30 a.m. at our Bethesda office.
We understand that you will be coordinating this meeting for all three licensees.
While we will provide the details of our intended review and will discuss your role at the upcoming meeting, prior to the meeting it would be helpful for you to give consideration to the various inherent design features in these plants that would be effective for the mitigation of a severe reactor accident.
To further assist you in preparation for the meeting, attached is a listing of considerations that the staff will be exploring.
S ncerely,
\\

Enclosure STAFF CONSIDERATIONS FOR DECEMBER 5, 1979 MEETING 1.
Japroved Interim Operational Actions: These actions involve, but are act necessarily limited to, such considerations as increased IE inspections, additional resident inspectors, augmented control room staffing and improved operator qualifications and training. Selected aspects from the Long Term Lessons Learned Report (NUREG-0585) may also be included as measures to further reduce the likelihood of a severe accident, e.g., corporate management accountability.
In addition, a review of the emergency procedures would be included to improve operational capabilities. This effort will also include an examination of the derating of the plant during an interim period while the actions in items (2) and (3) below are reviewed.
2.
Current Licensing Actions: The actions involved in this aspect of the plan will include implementation on a priority basis of those TMI-2 short term lessons learned actions stated in NLREG-0578 and Bulletin and Order review matters.
In addition prompt attention will be given to processing of outstanding amendments for these plants.
Subsequent actions would include implementation of any recommendations resulting from the resolution of unresolved safety items on a priority basis.
3.
Severe Accident Mitigation Features:
Tr. addition to the increased preventive actions described in (1) rnd (2) above, there are several measures that may be effective in mitigating the consequences of a major reactor accident involving core melt. Additional means such as derating and measures to augment the existing ECCS via an independent system are considerations that fall between prevention and mitigation and may be effective agents against a major nuclear accident. Such means also would include a bunkered system with a dedicated heat removal system.
