hat is being done to i.ssure public confidence in the results OUESTIO!!
<.of reviews and assessments required by the Comission's November 12, 1982 Order regarding the W. H. Zimmer Plant?
AUSWER The HRC is going to considerable length to assure that the public is kept well informed.
Public meetings are frequently held.
' Documents placed in the Public Document Room.
DISCUSSION:
A Plan of Action has been prepared and is being followed by the HRC staff for reviewing Cincinnati Gas and Electric Company's (CG&E) implementation of the Comission Order.
Copies of this Plan of Action were made available to interested members of the public.
In this Plan, emphasis has been given to providing meaningful opp,ortunity for public comment prior to the NRC staff taking action on the' various requirements of the Order.
This includes soliciting written comments from interested members of the public on submitted proposals from the licensee, holding meetings with the licensee in full view i
of the public, and responding to questions from the public at the conclusion of these. meetings.
For example, in evaluating CG&E's recommendation to have Bechtel conduct the management review of the Zimmer Project, Region III provided copies of CG&E's submittals and other background documents to interested parties for their comments. Based on the-staff's review of the comments received, Mr. James G. Keppler, Region III Administrator, held.a:
public meeting.in Cincinnati on January 5,1983 to obtain clarifying infor-mation on some of the comments and to provide. opportunity for other members of the public who did not submit written comments to express their views.
The 11RC staff will also require protocols governing communications between and among CG&E and the independent parties which may be involved in the Zimmer project.
Ur. der these protocols all recommendations, findings, evaluations and ex-changes of correspondence, including drafts, between the independent parties and CGLE shall be submitted to the Administrator #f NRC Region III at the same time they are submitted to CG&E.
All other communications and transmittals of information between CG&E and the independent parties shall be maintained in a location accessible for URC examination.
By these steps, the HRC staff will be able to monitor the independent reviews.
2 The protocols will also require tha't any discussions of substantive matters cr among CGLE and the independent parties or any discussion regard-bet. wee:
ir.g an interim report, findings, or conclusions of the independent parties Transcripts to CG&E 5e conducted in meetings open to public observation.
or written minutes of such meetings will also be kept.
The NRC staff also intends to conduct most me'etings it has with CG&E or the independent parties in public; however, there may be countervailing reasons which make it appropriate to conduct certain meetings just with CG&E and/or the independent parties.
All documents to or from the NRC staff regarding the independent reviews
. on Zimmer will be placed in the NRC Public Document Rooms in Batavia, Ohio and Washington, D.C..
The staff believes that its Plan of Action and the protocol will assure that the public's input is considered in decisions to be made under the Order and that the public has opportunities to follow the independt't It is our hope that these steps will cause the public to have reviews.

please ie.dicate five exanples of systen interactions of a kind that 7.'E ST *.0M.
the staff and/or P,r. Conran believe might occur at Shoreham.
i ANSWER.
i Five examples of systems interactions that could occur at a nuclear power station are:
A failure in a power supply causing spurious signals to the control system which in turn can result in opening of relief valves and subsequent loss 1.
of primary coolant.
A failure in power supply which could result in failure of control 2.
instrumentation leading to a transient resulting in reactor scram.
Failure of both vent and drain systems, due to a common discharge, could 3.
lead to a partial failure to scram in BWRs.
Failure of a turbine could generate a missile which in turn could damage 4.
safety related equipment.
A fire in some compartments could result in some loss of decay heat 5.
removal capability.
Current licensing requirements and safety review procedures used by the NRC staff are designed to address many different types of potential system inter-actions, including those listed above.
Adherence to the defense-in-depth principle and our related licensing requirements, such as the single failure criterien, result in redundant, independent and physically separated safety systems, and protection of each of the redundant safety systems against events such as high energy line breaks, missiles, high winds, flooding, seismic events Me believe that these licensing requirements, supplemented by the and fires.
review procedures of the Standard Review Plan.(which prov. ides for interdisciplinary reviews of safety systems and takes into account known potential system inter-actions significant to safety) provides reasonable assurance that operation of licensed nuclear power plants will not result in undue risk to the health and safety of the public.
The purpose of Unresolved Safety Issue A-17 " Systems Interactions in Nuclear Power Plants" is to provide confirmation that present licensing requirements and procedures are adequate (or in the alternative, to identify needed improvements) by detailed and systematic analyses of potential systems On one interactions and their safety significance on various plants.

QUESTION.
Please indicate three examples of structures, systems, ar,d components with regard to which there is disagreement between the NRC staff (and/or Conran) and the Long Island Lighting Company.
A':S'.:EF..
Three examples of structures, systems and components with regard to which there is an apparent disagreement between Mr. Conran and the Long Island Lighting Company are the effluent treatment, standby liquid control and rod block monitoring systems.
Based on these examples (which he does not believe are significant of and by themselves) Mr. Conran has raised the question of whether the applicant's understanding of which features of the plant are or should be termed "important to safety", as used in NRC regulations, particularly General Design Criterion 1, is sufficient to provide reasonable assurance the public health and safety during plant operation will not be endangered.
A meeting with Long Island Lighting Company and the NRC staff to discuss this issue will be held on February 18, 1983.
