evidence such as inspection records, turnover tags, material identiff-cation, nonconformance ard acceptance tag No violations were identifie .0 Snubber Inspection The inspector reviewed the general site activities related to snubber This included review of the following:

Final stroking program being performed by the architect engineer (Bechtel Corporation)

Observations of work being performed on drywell snubbers a

Quality control inspection records related to those snubbers observed

Status of responsibility for Technical Specification (TS) surveil-lances after construction turnover of snubbers

• FSAR requirements for snubbers

Snubber records and test documentation Final Stroking Program The inspector reviewed the final snubber stroking program being performed by Bechtel per procedure SWP/P-143 Revision 1. The program objectives are to demonstrate that snubbers have not been damaged after final inspection and that snubbers are free to move through their full stroke range. The requirements of this procedure are applicable to all sr.ubbers both mechanical and hydrauli The inspector determined that the plant has 50 hydraulic snubbers manufactured by E System Company, Montek 01 vision and approximately 1200 mechanical snubbers manufactured by Pacific Sci mtific Company Ken-Tech Divisio The inspector verified that this program was completeJ in December 1985 ard was satisfactorily perforced in acc rdance with the procedur .2 Work Observations in Drywell Based or the final strokin; program findings of damaged snubbers and protective covers removed.

P-375. 412, and 504) for Shock Suppressor Stroking, and Torquing defined the required work activit OC was fully involved and the records were signed at each acceptance point and were properly complete .4 Status of TS Snubber Surveillance Responsibility The inspector reviewed the status of future responsibility within the TS surveillance requirement The inspector determined that all TS visual and functional test surveillances are under the ISI department and that only the service life monitoring item is under the mainte-nance department. The licensee's personnel stated procedures are in process to enable performance of these activities but are not com-plet .5 FSAR Requirements for Snubbers The inspector reviewra the FSAR provisions related t- design spect-fication requirement s, performance tests ircluding bn'.h troduction and qualification trsts, and the construction verifi"ition, preopera-tional and power te.t progra Each of these areas rare determined to be adequately addresse .6 Snubber Records and Test Documentation The inspector reviewed the snubber documentation records and deter-mined that the individual croduction test records for PSA r.;echanical snubber were not in the dccu entation ca:kage. (It was noted that I

the production test records of the hydraulic snubbers was in the dccumentation package.)

The inspector verified that FSAR required production tests of all

'

snubbers. The inspector review of the Bechtel ordering specification P-401Q determined that it does not contain provisions for production testing records for mechanical snubbers. Therefore, the inspector could not obtain any verification that individual production testing was performed, if performed where these records are and that they met the manufacturers functional operability criteri This item remains unresolved pending the ifcensee providing information that: production testing was performed on mechanical snubbers and availability of the test data, test results met the acceptance criteria, and test records are those of the installed snubbers (50-354/86-13-01).

4.0 Status of Previously Identified Items 4.1 (Closed) Circular No. 77 CI-11 leakage of Containment Isolation Valves with Resilient Seats. This circular advised of excessive leakage problems in large butterfly valve elastomeric seat material losing resiliency, wearing due to cycling, and degradation due to environmental conditions.

i The licensee has BIF containment isolation valves with EDPM seat material (not the manufacturer or seat material described in the IE Circular). Additionally, the seat material will be replaced every five years per the manufacturer's maintenance procedure. The Itcen-

see is knowledgeable of the leakage concerns and plans to address this in their future maintenance progra This item is close .2 (Closed) Circular No. 78-CI-07 Damaged Comoonents of a Bergen-Paterson Series 250d'0 Hydraulic Test Stano. This test stand utilizes a 2 pin fixed loading system, which unlike the actual snubbers with spherical type bushings, doesn't allcw transmission of bending moments in the vertical plane. Bergen-Paterson recommended periodic inspection and provided acceptance criterion for the fixture compo-nents. The NRC circular asked licensee to review their snubber testing device to determine if a similar problem could develop and to consider the need for periodic inspectica. and replacement of components.

The licensee's Response Coordination Team has reviewed the circular, and the Technical personnel is knowledgeable about the need to pre-vent misalignment bending moments. The licensee has not purchased ,

Bergen Paterson snubbers and does not intend to purchase a Bergen Peterson hydraulic test stand. The purchase of a test machine has not been authorized and is still being considered, however, the licensee has committed to operating and maintaining a snubber test '

stand in accordance with the manufacturers recommendations if one is purchase The licensee's activities satisfactorily address the IE circular concern This item is close .3 (Closed) _ Circular No. 80-CI-10 pertaining to failure to maintain Environmental qualification of equipmen The circular recommends that the licensee review its current mainte-nt ce procedures and administrative policies to ensure that adequate administrative controls exist to ensure equipment that is environ-

mentally qualified is not degraded upon completion of maintenanc The licensee has reviewed equipment subject to harsh and mild environ-ments to identify maintenance and surveillance action required to maintain the qualified condition of equipment. Site engineering instruction (SEI) 2-6 has been issued and equipment qualification sheets completed which ider.tify the requirements to the plant mainte- '

nance department.

The redesign of twelve valves' control logic impacted the Bailey Equipment and the remaining five valve control logic redesign impacted General Electric equipment. One additional valve was iden-tified requiring control logic m*odification for sensing of diverse

parameters for isolation initiatio This modification had no impact on Bailey equipmen Modifications were made in accordance with General Electric FDI-WTJB and P&ID Nos. 43, 49, 51, 55 and 5 The Test Package Release (TPR) - RLC-0197 included the retest of the modification (DCP-146) per General Test Procedure No. 7 Revision 1 and No. 27 Revision 2.

The licensee also has FSAR commitments te verify snubber functiona-bilit The inspector verified that the Architect Engineer (Bechtel Corpora-tion) has recently completed (in December 1935) the Final Snubber Stroking Program as defined in procedure SWP/P143 Revision 1. All snubbers both mechanical and hydraulic have been stroked. This program identified concerns in the drywell, required an additional walkdown and inspection of drywell snubcers, and repair and replace-ment of any damaged snubbers. This activity is approximately 95%

completed.
