FACILITY: Browns Ferry Nuclear Plant Unit 2
SUBJECT:
MINUTES OF THE JUNE 30, 1988 PEETING WITH THE TENNESSEE VALLEY AUTHORITY ON THE CRITERIA 0F IEB-79-14 RESOLUTION AT BROWNS FERRY (TAC 00015,00016,00017)
On Thursday, June 30, 1908, a meeting was held at the Office of 3pecial Projects (OSP), NRC headquarters in Rockville, Maryland with the Tennessee i Valley Authority (TVA). The meeting was held as a follow-up to a June 16, 1988 OSP/TVA meeting. A list of attendees is attached as Enclosae 1.
l The purpose of the meeting was to discuss a new propesal icy TVA for the large bore piping seismic evaluation program. The NRC staff had provided its provisional acceptance of the overall program plan for resoiving IE Bulletin
- 79-14 in a meeting with TVA on March 17, 1988. Since TVA's propa:ed program plan projected that approximately 50% of the IE Bulletin 79-14 analyt.is effort would be completed prior to the Browns Ferry Unit 2 restart, the staff made i:s acceptance of the program contingent on the re;ults of the completed analyses.
The staff planned to audit this effort when the analysis was approximately 20%
1 complete. TVA indicated that it had approached the 20% completion milestone j and TVA requested a June 16, 1988 meeting to discuss its proposal for the evaluation techniques.
d During the June 16, 1988 meeting. TVA identified nine factors involved with J the Browns Ferry pipe and pipe support seismic design rethodology for which TVA requested staff acceptance and approval. According to TVA, these nine factors generally involved seismic analysis methods that were not clearly specified in the Browns Ferry FSAR. The staff agreed to review these factors and to provide TVA with its position in a followup meeting (the subject of this Meeting Summary). TVA agreed to provide additional infonnatiot. to support the technical adequacy of the nine factors.
TVA's proposal for addressing the technical adequacy of tne nine factors
, involved a sample analysis effort. The details of TVA's proposed sample analysis were presented in the meeting slides certained in Enclosure 2. The proposed sample involved the corparison of the results of an analysis of five piping problems using current analysis rethods and acceptance criteria with
- the results of an analysis of the same five problems using the proposed Browns 1
Ferry analysis rethods. During the TVA presentation, the staff questioned
' whether scre of the proposed methods used for the sample met current licensing criteria and analysis techniques. In addition. TVA was proposing acceptance 4
criteria to evaluate the sarple results which were less conservative than current i licensing criteria accepted by hRC. TVA had previously propcsed to use a set of interim criteria similar to the interim criteria used at Sequoyah to determine the pipe support modifications required for Browns Ferry restart 0l t

. 2 (Meeting Sumary dated January 19,1988). These interim criteria would be used with the old analysis methods. Based on these considerations, the staff did not endorse TVA's newly proposed sample analysis techniques. .
The staff presented its position on the nine factors involved with the Browns i I
Ferry pipe and pipe support seismi: design inethodology. The staff's position
- was based on criteria in Browns Ferry's FSAR, the staff's original SER; or.
where explicit Browns Ferry licensing guidance was not available, accepted NPC ;

(Meeting Sumary dated January 19,1988). These interim criteria would be used with the old analysis trethods. Based on these considerations, the steff did not endorse TVA's newly proposed sample analysis techniques.
The staff presented its position on the nine factors involved with the Browns Ferry pipe and pipe support seismic design methodology. The staff's po.ition was based on criteria in Browns Ferry's FSAR, the staff's original SER; or, ,
where explicit Browns Ferry licensing guidance was not available, accepted NRC staff practice or guidance from previous lice.1 sing reviews. The staff's position on the nine factors is sumarized below:
FACTORS
- BF ORIGINAL OSP STAFF RESPONSES DESIGN BASIS
- 1. Vertical Seismic 0.079 OBE Not Acceptable Response Input 0.139 SSE Not Acceptable 1
- 2. Seismic Damping 0.5% Acceptable OBE/SSE ,
- 3. Peak Broadening No Not Acceptable
- 4. Seismic Anchor Some Should be included in <

- 7. Combinstion of Hades SRSS Acceptable Combination of Dir. Acceptable
- 8. Closely Spaced Modes No Not Acceptable
- 9. Rigid Range 20 Hz or Acceptable 30 Modes l
(*As proposed by TVA - See Enclosure 2)
TVA 1-dicated that it would require time to review the staff's cornments. The ,
proposed OSP piping audit scheduled for July 18.22 was placed on hold pending TVA's responses to OSP comments.
