This routine, unannounced inspection was in the areas of issues related to IEB 79-02 and 79-14, and the Mark I Containment, Plant Unique Analysis Report (PUAR). More specifically, the six items identified in Report No. 50-325, 324/88-36 were addresse Also, the inspector told the licensee what he would address 50-325/82-19-01 and 50-325, 324/87-18-02, which appear to be the same issue, and 50-325, 324/88-BU-02, which appears to be an erroneous entry, as well as 50-324/80-29-0 Results:

In the areas inspected, violations or deviations were not identifie Based on current status and licensee commitments, including schedules and manpower forcasts, IEB 79-14 is closed. Also, work has been completed and the final report for IEB 79-02 is being prepered. The suppression pool issues appear to be a question of documentation and will remain open pending review of the appropriate documentatio PDR 890620 ADOCK 05000324 PDC

The objective of this Bulletin -is to verify. that the_ seismic analysis applies to the actual installed configuration of safety-related piping, Two piping verification walkdowns have been performed. One was'done shortly after the Bulletin was originally. issue Later modifications were incorporated due to new loads, design changes, or other requirement The- Quality Control Department conducted inspections of the modified systems only because there was no requirement for inspection of. the non-modified system Afterwards, the Quality Assurance Department-conducted a surveillance (86-004) to verify: the As-Built pipe. support I

drawings. Various discrepancies were noted in the piping systems which

!- had not been modified (nor inspected by QC). In-early 1988, management l- decided to~ conduct a second verification walkdown, on -the piping systems

which had not been modified after the original IEB 79-14 verification walkdow This walkdown was done by teams of two field engineers and was not inspected by QC nor audited by Q In September 1988, an NRC inspector randomly selected 33 pipe supports on five isometeric drawing Eighteen supports were from the original walkdown effort on which no modifications had been made, and on which the As-Built Phase II Piping System Walkdown Verification Program had been completed (that is, without QC/QA Reverification or Audit). Fifteen supports were the modified supports, which had been QC inspected after the modifications were completed. Discrepancies were noted on 7 of the 33 supports 1 of the 5 isometric drawing These results prompted management to undertake one more all-inclusive j effort to reconcile the As-Built piping and supports with their respective '

drawings and calculation Entitled "UE&C Piping Design Turnover l Program", it consists of two phases, the first of which has been

complete Phase I was basically a preparation phase in support of Phase II. It involved the identification of UE&C pipe stress and pipe support calculations of record, packaging to place the calculation packages in a readily useable form, transmittal of the calculations to CP&L, transfer of piping and pipe support design responsibility to CP&L, and rP&L generation of pipe stress isometric drawings as required to match l tb* UE&C calculations. Phase II will involve sclected walkdowns to define t.e As-Built configuration of the plant, updating calculations to reflect the As-Built configuration of the plant, enhancement of calculations to resolve identified problems, and updating drawings to reflect the As-Built configuration of the plan This program is designed to document piping and pipe support criteria used by UE&C to design BSEP; assemble piping and pipe suppor_t calculation packages which represent the As-Built configuration of the plant, satisfy regulatory commitments, and can be used by CP&L personnel for emergency evaluations or future plant modifications; transfer piping and pipe support documentation from UE8C to CP&L; transfer piping and pipe support design responsibility from UE&C to CP& A detailed plan was been devised to assure that the measurements taken by the walkdown teams are accurate and that their information is properly reflected on their respective drawings and calculations. This program is currently scheduled to be completed by late 199 With the licensee commitment to this program and considering numerous past walkdowns, as well as NRC inspections which did not uncover any major discrepancies, IEB 79-14 is hereby closed for both Units 1 and .

The Suppression Pool Monitoring System had been installed before the j Mark I Containment Long Term Modification Program was initiated but j it did not meet the requirements outlined in NUREG-0661, Mark I 1 Containment Long Term Program, or NUREG-0783. Plant Modification  ;

No.81-251 was implemented to meet those requirements. During the  !

88-36 inspection, the licensee was unable to present documentation showing NRC approval of the modified installation. During the  !

current inspection, the licensee presented a letter, dated j March 1984, from the NRC (Division of Licensing, Washington, D.C.),  !

which states in part, "Where deviations from the Acceptance Crfteria j specified in NUREG-0661 wave been taken, they have been found  !

acceptable." The letter was referring to Revision 0 of the Brunswick- i Plant Unique Analysis Report (PUAR) dated October 1, 198 However, the only copy of the PUAR available was Revision 1, dated ,

December 23, 198 The inspector wanted to assure that no changes j were introduced in Revision 1 concerning the Suppression Pool j Temperature Monitoring System which were not addressed in the NRC  !

acceptance letter. Pending a comparison of Revisions 0 and 1 of the  !

PUAR, UNR 50-325, 324/88-36-01 remains ope ,

Verification Program and the Modified Systems with QC Inspection ,

The inspector spoke to the Principal Engineer (NED) and the Quality Control Supervisor who outlined the plan to be used in the "UEAC Piping Design Turnover Program", which will be used to evaluate some 7330 pipe supports and walkdown about 550 To reduce discrepancies discovered by the QA audit, the walkdown verification program has been reviewed and modified. The walkdown teams will consist of two members, a QC inspector and a field engineer. These teams will work together to review all support drawings per isometric before conducting a walkdow Upon completion of a walkdown, both members

will transfer the field data unto individual ledgible drawings, l verify the data to ensure its accuracy, sign the drawings to indicate their agreement, and turn the drawings in for processing / record  ;

purposes. Engineering will maintain all field copies and make all i modifications / revisions to the drawings. The updated drawings will j be sent to QC for review to assure accurate incorporation of walkdown information. Upon receiving QC concurrence, Engineering will sign  ;
