SAFETY EYALUATION REPORT BY THE OFFICE OF NUCLEAR REACTOR REGULATION EQUIPMENT tlUALIFICATION BRANCH FOR ROCHESTER GAS AND ELECTRIC CORPORATION GINNA.
DOCKET NO. 50-244 ENVIRONMENTAL tlUALIFICATION OF SAFETY-RELATED ELECTRIC EQUIPMENT INTRODUCTION General Design Criteria 1 and 4 specify that safety-related electrical equipment in nuclear facilities must be capable of performing its safety-'
related function under environmental conditions associated with all
,normal, abnormal, and accident plant operation.
In order to ensure com-I pliance with the criteria, the NRC staff required all licensees of operating reactors to submit a re-evaluation of the qualification of safety-related electrical equipment'which may be exposed to a harsh environment.
Qv+PE.r BAC GROUND, On February 8, 1979, the NRC Office 'of Inspection and Enforcement (IE)
- issued to all licensees of operating plants (except those included in the systematic evaluation program (SEP))
IE Bulletin (IEB) 79-01, "Environ-mental gualification of Class IE Equipment."
This Bulletin, together with IE Circular 78-08 (issued on May 31, 1978), required the licensees to t
perform reviews to assess the adequacy of their environmental qual'ifica-tion programs.
On January 14, 1980, NRC issued IE Bulletin 79-01B which included the DOR r
guidelines and NUREG-0588 as attachments 4 and 5, respectively.
Subse-
- quently, on May 23, 1980, Commission Memorandum and Order CLI-80-21 was issued and stated the DOR guidelines and portions of NUREG-0588 form the'requirements that licensees must meet regarding environmental 82i22000i3 82i2i3 PDR ADOCK 05000244 p
2 qualification of safety-related electrical equipment in order to satisfy those aspects of 10 CFR 50, Appendix A, General Design" Criterion (GDC) 4.
Supplements to IEB 79-01B were i.ssued for further clarification and definition of the staff's needs.
These supplements were issued on February 29, September 30, and October 24, 1980.
In addition, the staff issued orders dated August 29, 1980 (amended in I
September 1980) and October 24, 1980 to all licensees.
The August order required that the licensees provide a report, by November I, 1980, docu-
'menting the qualification of "safety-related electrical equipment.
The'October order required the establishment of a central file lo'cation for tt~raintenance of all equipment qualification records.
The central file was mandated to be established by December 1, 1980.
The staff subsequently issued Safety Evaluation'Reports (SERs) on environmental qualification of safety-related electrical equipment.to licensees of all operating plants in mid-1981.
These SERs directed licensees to "either provide documentation of the missi'ng qualification information which demonstrates that safety-related equipment meets the DOR Guide-lines or NUREG-0588 requirements or commit to a corrective action (re-qualification, replacement (etc.))."
Licensees were required to respond to NRC within 90 days of receipt of the SER.
In response to I
the staff SER issued June 1>
1981, the license submitted additional information regarding the qualification of safety-r'elated electrical equipment.
I
3 EVALUATION The acceptability of the licensee's equipment environmental qualification program was reviewed for the Division of Engineering by the Franklin Research Center (FRC) as part of the NRR Technical Assistance Program in support of NRC operating reactor licensing actions.
The consultant's review is documented in the report "Review of Licensees'esolutions of Outstanding Issues from NRC Equipment Environmental gualification Safety Evaluation Reports," which is attached.
We have reviewed the evaluation performed by our consultant contained in, the enclosed Technical Evaluation Report (TER) and concur with its bases and findings.
Our r'eview has also revealed certain discrepancies'in the TER which are being corrected by this SER as follows:
o.
Delete the third paragraph on page 1-9 of the TER.
o Delete the second paragraph on page 1-10 of the TER.
4 The staff has also reviewed the licensee's justification for continued operation regarding each item of safety-related electrical equipment identified by the licensee as not being capable of meeting environmental qualification requirements'or the service conditions. intended.
CONCLUSIONS Based on the staff's review of the enclosed Technical Evaluation Report and the licensee's justification for continued operation, the following conclusions are made regarding the qualification of safety-related elec-trical equipment.
Continued operation until completion of the licensee's environmental qualification program has been determined to not present undue risk to the public health and safety.
Furthermore, the staff is continuing to review the licensee's environmental qualification program.
If any ad-ditional qualification deficiencies were identified during the course of this review, the licensee would be required to reverify the justification for conti nued operation.
The staff will review this information to ensure that continued operation until completion of the licensee's environmental I
qualification program will not present undue risk to the public health and safety.
In this regard, it is requested that the licensee do the fol 1 owing:
o Resolve any deficiencies identified in Appendix 0 of the FRC TER regarding justification for continued operation.
If as a
result of resolving these deficiencies, the previous justifi-cation for continued operation is changed, provide within thirty (30) days of receipt of this SER the new justification for continued operation regarding each affected item.
The major qualifi/ation deficiencies that have been identified in the enclosed FRC TER {Tables 4-1, 4-2, 4-3 and 4-4) must be resolved by the licensee.
Items requiring special attention by the licensee are summarized bel ow:
o Submission of information within thirty (30) days for items in NRC categories 1B, 2A and 2B for which justification for continued operation was not previously submitted to NRC or FRC, o
Resolution. of.aging,. and.qualified life deficiencies, C
o Resolution of qualification time requirements.
The licensee must provide the plans for qualification or replacement of the unqualified equipment and the schedule for accomplishing its proposed correction action.
PROPRIETARY REVIEM Enclosed in the FRC Technical Evaluation Report (TER) are certain identi-I fidp tih h i<<i i
1i d
b During the preparation of the enclosed
- TER, FRC used test reports and other documents supplied by the licensee that included material claimed to be proprietary by their owners and originators.
NRC is now prepar-ing to publicly release the FRC TER and it is incumbent on the agency to seek review of all claimed proprietary material.
As such, the licensee is requested to review.the enclosed TER with their owner or originator and notify NRR within'seven (7) days of receipt of. this SER whether any portions of the identified pages still require proprietary protection.
If so, the licensee must clearly identify this information and the specific rationale and justification for the protection from public disclosure, detailed in a written response within twenty (20) days of receipt of this SER.
The level of specificity necessary for such continued protection should be consistent with the criteria enumerated in 10 CFR 2. 790(b) of the Commission's regulations.
