Re ort Details III. Engineering E1 Motor-Operated Valve Program Review (Tl 2515/109)

Bac~caround On October 27 through November 7, 1997, the NRC staff conducted an inspection of the motor-operated valve (MOV) program developed at the Ginna nuclear power plant in response to Generic Letter (GL) 89-10, "Safety-Related Motor-Operated Valve Testing and Surveillance."

In Inspection Report 50-244/97-13,the NRC staff noted substantial improvement in the MOV program since the previous inspection, However, the staff was not able to reach closure of its review of GL 89-10 at Ginna because input assumptions in the licensee's MOV calculations for specific MOVs were not validated adequately and the licensee had not finalized design-basis calculations under the quality assurance plan.

In a letter dated December 24, 1997, forwarding NRC Inspection Report 97-13, these findings were characterized as violations of 10 CFR 50 Appendix B, Criterion Vll, "Control of Purchased Material, Equipment, and Services."

On February 26, 1998, the NRC staff met with the licensee to discuss its response to the violations identified in NRC Inspection Report 97-13 and the other MOV inspection findings (copies of overheads are attached).

During the meeting, the licensee described its incorporation of the findings from the NRC inspection and the results of independent peer feedback into the GL 89-10 program at Ginna.

The licensee demonstrated that it had taken aggressive action to resolve the concerns raised in NRC Inspection Report 97-13. The licensee also noted that the MOV program at Ginna would continue to be improved and updated accordingly.

E1.1 Periodic Verification of Desi n Basis Ca abilit a.

Ins ection Sco e

The inspectors reviewed the licensee's plans for periodically verifying MOV design-basis capability pursuant to GL 96-05, "Periodic Verification of Design-Basis Capability of Safety-Related Motor-Operated. Valves."

b.

Observations and findin s In a letter dated November 18, 1996, RGSE committed to implement a program for periodic verification of design basis capability of safety-related MOVs. This program would incorporate the results of self-assessments of the GL-89-10 program and efforts of the Westinghouse Owner's Group.

By letter dated March 3, 1998, RGSE provided a summary description of its Periodic Verification program to the NRC along with its MOV closeout lette The Periodic Verification program consists of three elements; (a) static testing, (b)

dynamic testing and (c ) feedback data evaluation (including tracking and trending),

and is described in Attachment J of the MOV Program Plan, EWR 5111 and in Engineering Procedure EP-3-P-170, "MOV Program Tracking and Trending."

C.

Conclusions The licensee's MOV periodic verification program was acceptable for GL 89-10 program closure.

Further NRC review of this program will be conducted under GL 96-05.

E8 Miscellaneous Engineering Issues E8.1 Closed Unresolved Item 50-244 97-13-01: Design Control for SMARTBOOK.

The inspectors had reviewed the licensee's administrative requirements for use of the SMARTBOOKsoftware program.

Engineering Procedure EP-3-P-0171 (Revision 1, dated March 10, 1998) provides for independent review of the SMARTBOOK

. calculations.

A sample of MOV calculations indicated that independent reviews by licensee personnel had been performed.

The inspectors concluded that RGSE had implemented adequate administrative controls to govern the use of the SMARTBOOKdatabase.

No violation of NRC requirements were identified. This unresolved issue is closed with no pending enforcement action.

E8.2 Closed Violation 50-244 97-13-02: Failure to approve and accept vendor calculations The inspectors confirmed that the licensee had revised Engineering Procedures EP-3-P-0154 (Revision 2, dated April 15, 1998) and EP-3-P-0122 (Revision 2, dated February 10, 1998) for control of vendor and in-house calculations.

The inspectors also reviewed a sample of MOV calculations to verify that the licensee was evaluating work conducted by its contractors adequately. The licensee reported in a telephone discussion on May 28, 1998, that training of applicable personnel on the MOV Program and EPRI MOV Performance prediction model (PPM) had been completed.

Based on its review, the inspectors considered the actions taken and planned by the licensee as described in the letter dated March 3, 1998, to provide an acceptable response to this violation. This violation is closed.

E8.3.

Closed Violation 50-244 97-13-03: Inadequate verification of design assumptions for MOV 313 and RCS 515/516 The inspectors confirmed that the licensee had established correct torque switch settings for MOVs 515, 516 and 313 for these valves to reach their fullyclosed positions.

The calculations for these MOVs indicated that the torque switches should be set for the valve to reach a wedged-disk seating position.

The licensee established thrust requirements for MOVs 515 and 516 using the EPRI MOV PPM.

The licensee indicated in the telephone discussion on May 28, 1998, that MOV 515 is installed with the valve disks in the preferred orientation and that the valve disks

for MOV 516 will be placed in the preferred orientation during the next refueling outage.

With respect to MOV 313, the licensee referenced a contractor study that predicted a 0.35 valve friction coefficient based on the limited, contact stress and low differential pressure experienced by the valve and then applied this friction coefficient in the EPRI MOV PPM to demonstrate the capability to hard seat the valve assuming a conservative disk orientation and specifically analyzed disk-to-seat contact mode.

Further, the licensee set the torque switch for MOV 313 to deliver the maximum allowable thrust above the minimum requirements specified in the contractor study.

The licensee's valve friction coefficient assumption was also supported by a partial differential-pressure test of MOV 313 that revealed minimal dynamic thrust effects when closing the valve. The inspectors considered the licensee to have established a reasonable torque switch setting for MOV 313 that provides for wedging of the disks into the valve seat.

Based on their review, the inspectors considered the actions taken and planned by the licensee as described in the letter dated March 3, 1998, to provide an acceptable response to this violation.

This violation is closed.

Closed Ins ector Follow-u Item 50-244 97-13-04: Grouping Criteria for Groups B,D,E This item involved the valve factors assumed by the licensee for sizing and setting of MOVs in the GL 89-10 program at Ginna.

In response to the previous inspection findings, the licensee regrouped the MOVs in its GL 89-10 program and strengthened the bases for the valve factors assumed for the valve groups.

The inspectors reviewed the valve groups, and the thrust and torque (including valve factor) justifications provided in the attachment to licensee's letter dated March 3, 1998, on the completion of the GL 89-10 program.

The licensee provided reasonable bases for its predicted thrust and torque requirements (including valve factors) with limited confirmatory action planned for the long term.

For example, the licensee had established plans to perform dynamic tests or analyses using the EPRI MOV PPM that will be tracked by the licensee through its CATS or REPTASK system.

Therefore, the licensee's plans are acceptable for GL 89-10 program closure and this inspector follow-up item is closed.

Closed Ins ector Follow-u Item 50-244 97-13-05: Valve factors for Groups A,C,H,J,M,N This item involved the licensee's use of data from friction studies conducted by EPRI, In its revised justification for thrust and torque requirements, the licensee strengthened the bases for the valve factors assumed for the valve groups.

In the updated justification, the licensee did not rely solely on EPRI friction tests, but also on more applicable valve test information or EPRI model evaluations.

The inspectors considered the licensee to have adequately addressed the issue.

Therefore, this inspector follow-up item is close V. Mana ement Meetin s X1 Exit Meeting Rochester Gas and Electric Corporation representatives were informed of the scope and purpose of this inspection at an entrance meeting on April 16, 1998.

Observations and findings were discussed with licensee representatives at an exit meeting conducted on June 11, 1998. No proprietary materials were included as part of this report.
