neganization and the assignment to an implementing organizatio The MMRT consists of the Assistant Station Manager 0&M, Superintendent Operations, Superintendent Radiological Protection, Superintendent Station Engineering, Superintendent Nuclear Site Services, Superintendent Outage and Planning, and the Superintendent Maintenanc Based on _ discussions with licensee engineering personnel, and review of the above documentation the inspectors concluded that the licensee has a satisfactory prioritization process for identifying and implementing plant design changes to improve reactor safet Planning, Development and Implementation of Plant Modifications The inspectors reviewed the DCPs listed below to: 1) determine the adequacy of the 10 CFR 50.59 evaluations performed; 2) verify that the DCPs were reviewed and approved in accordance with TS and applicable administrative controls; 3) verify the subject modifications were installed (for those that could be physically inspected) in accordance with the DCP package; 4) verify that-applicable plant operating and design documents (drawings, plant procedures, FSAR, TS, -etc.) were revised to -reflect -subject modifications; 5) verify that the modifications-were reviewed and-incorporated into the operations training _ program as applicable; and 6) verify that post modification test requirements were specified and that adequate testing was performed. The following DCPs were reviewed:
DCP 92-104,. Rebuilding of Selected SW MOVs This DCP involved the inspection and rebuilding of the Unit 1 16 inch SW butterfly valves 1-SW M0V-103A,B,C,D-and 1-SW MOV-104A,B,C,0 in order to reduce the high seating torque experienced during seating of the valves._ These
- valves provide isolation of the RSHX and are safety relate Modifications to the valves included installing a stainless-steel sleeve in the stub shaft and valve shaft bore; increasing the diameter (from 7/16-inch to 5/8-inch) of _the groove pins holding the disc to the valve shaft; and replacing the thrust collar with one shrunk fit to= the valve shaft. The new thrust collar design was also installed on -
the 24-inch SW butterfly valves 1 SW MOV-101A,B,C,0; J-SW-MOV-102A,8; l-SW-MOV-105A,B,C,D; and 1-SW MOV-106A,B.-

The 24 inch valves are located in the SW supply and return lines to the RSHXs. The inspectors reviewed the safety evaluation for adecuacy. Areas addressed in the safety evaluation includec , but were not limited to, seismic, material compatibility, effects of weight changes, and post modification test requirement During review of the DCP and associated field changes, the inspectors noted that the diagnostic testing performed on the valves was being used for information Jurposes onl The data were not used for acceptance of tie work performed under the DCP nor for setting of the torcue switch and the torque switch bypass. The basis arovidec in the change was.-
that the test _ equipment accuracy 1ad not been-independently validated. The diagnostic equipment was used to aid the MOV Engineer in evaluating the effect that the repairs made to the valve internals had on the motor operators. The valves were stroke tested and the motor operator current checked to verify operabilit Evaluation of the diagnostic test data-by the MOV Engineer indicated that there were no conditions internal to the valves which would be detrimental to the motor operator. During discussions with the inspectors, licensee personnel indicated that a letter modifying GL 89-10 commitments on DP testing of quarter turn valves would be sent to the NRC. The licensee's Gl. 89 10 program will be reviewed during subsequent inspection The inspectors determined from the information-reviewed that this DCP was implemented in accordance with licensee procedures and control * DCP 91-205, Auxiliary feedwater Total Flow Indication Removal This DCP involved removing the' AFW total flow indicator from the Unit 2 control room. in addition, the logic card which summed the three individual AFW flow loo)s and associated cabling were removed from the process casinets in the emergency switchgear room. The-flow indicators were installed under DCP 87-31. During a review of the E0Ps to identify revisions which might be required as a result of DCP 87-31, the licensee determined that use of the total-flow indicator did not provide accurate information for all credible situations. -This modification was never installed-on Unit 1. The inspectors reviewed the safety evaluation t verify that items considered included human factors, instrument accuracy _ calculation,- and Appendix The inspectors concluded that the safety evaluation bounded the scope-of the work covered by the DCP and the DCP.was implemented-in accordance with licensee procedures. The inspectors did note, however, that the original design =

review for DCP 87-31 could have prevented the unnecessary plant modification that was later removed. The inspectors noted that the licensee's design change process has been enhanced since the original review of DCP 87-31 which provides for a more thorough upfront review of CCP *
DCP 92-252, Missile Protection for EDG Fuel Transfer Piping This DCP involved installing a structural steel plate missile barrier in each of the Unit I and Unit 2 EDG rooms in order to protect short runs of exposed 1-1/2 inch and >
l inch diameter EDG fuel oil transfer lines from tornado generated missile hazards. The two lines supply fuel oil to each EDG, one primary supply and one standby supply. The fuel supply lines are located near the intake louvers in i each EDG roo The intake louvers for each EDG room were not designed to protect the short run of fuel oil transfer piping from a missile hazard. The inspectors reviewed the safety evaluation to verify that items considered included seismic, Appendix R, and TS surveillance requirement The inspectors concluded that the safety evaluation ;
addressed the scope of work and the DCP was implemented in accordance with licensee procedure * DCP 84-71, Pressurizer Safety and Relief Valve Discharge Pipe Support Modifications In response to NUREG 0737, item 11.0,1, Virginia Electric-and Power Company (VEPC0) analyzed the transient fluid loads ,
'
which would result when the pressurizer safety valves (PSVs)
and/or Power Operated Relief Valves (PORVs) lift and system-pressure accelerates the loop seal cold water through the valvo and discharge piping. .The analysis indicated that significantly high fluid transient .. loads would result Lin-unacceptable stress levels and pipe support loads, it was determined that the installation of reflective metal thermal insulation on the loop seals (loop seal- ovens) to maintain a--
water temperature greater than 400'F and modification of the PSV discharge piping supports would adequately accommodate the fluid transient loading. The loop seal: ovens have been'
installed on both. Units and the PSV discharge pipe support; modifications has been completed on Unit 2. -DCP 84-71 was '
issued to modify the PSV discharge pipe support system in Unit 1. -The proposed modification' included addition of~.
supports, deletion of supports and modification of existing supports.

was closed out in 1992 without completion of the support modifications. The DCP was to be implemented.in the 1985 refueling outage. However, the license determined that the project was so extensive that completion in a single outage would significantly extend the outage time. Consequently the controlling procedure was revised twice, once in field Change (FC) FC-4 in 1985 and again by FC 47 in 198 The project was divided into three phases as follows:
Phase ! - Modification upgrade of load capacity of an existing support. For instance replacement of a 11 inch hydraulic snubber with a 31 inch hydraulic snubber. In this phase, support functions were not changed and supports were not added, deleted or relocated. The original stress analysis remained vali Phase 11 - In this phase all additional supports required for the piping upgrade were to be installed except they would not be connected to the pipin Therefore, the original pipe stress analysis remained '
vali Phase Ill - All physical connections for added supports to the piping will be made and disconnection between piping and existing supports to be removed will be performed. These changes to support function -
and location of supports are validated by the revised pipe stress mode Phase I and Phase 11 were implemente Phase 111 was not; implemente Consequently, .the as left pipe support- system conforms to the original stress analysis.- The close out wa's considered prudent since 1) the DCP_had become difficult to work under significantly different design control procedures, 2) the package had become complex (75 revisions).
and difficult for craftsmen to follow and, 3) management was considering a different resolution.to item II.D.1 which may not require the support modification '
The DCP 84-71 close out was' documented in the package and-included a system walkdown, verification of-document. updates; and revision of system description-to reflect the a installed system configuration. Post modification-testing:

documents-and impact on design basis document The licensee provided a letter to the f4RC dated flovember 12, 1992, which indicated that the modification to meet fiUREG 0737, item II.D.1 on Unit.I will consist of draining off the loop seal water to provide a steam environment.at the PSVs. This modification has been deferred until the f1RC has completed the review of the-Westinghouse Owners Group final report on PSV set)oint drift since f4RC positions on draining the loop seal mig 1t affect the planned modificatio * DCP 92 182, RVLIS Tubing Configuration Change, Unit 2 *
This DCP was issued due to leakage at the Reactor Vessel Level Indication System-(RVLIS) tee connection at.the seal table. When reviewing the condition the licensee found that subsequent to installation of the RVLIS seal table fittings on Unit 2 and prior to the Unit 1 installation, the Westinghouse drawing 1598E06 which controlled the installation was revised. The change at the too connection at the seal table reduced the number of fittings and :

d. Configuration Control The inspectors reviewed selected controls developed and implemented by the licensee to ensure that applicable design documents and procedures affected by completed DCPs were updated in a timely manner to reflect the as-built plant. Documents reviewed included procedures VPAP-0301, Design Change Process and ADM-6.10, Annotation and Revision of Station Drawing These documents describe the controls for updating applicable priority and non-priority plant documents as a result of a DCP; and for annotating, revising, and distributing station drawing Priority documents include drawings, procedures, and other controlled plan documents which are needed to support operation of the Priority documents are required to be revised before returning the affected system or component to operable statu Controlled drawings at North Anna comprise three categories which are priority drawings, test loop diagrams, and non priority drawing Priority drawings are those required in the control room, 150, and operation / maintenance coordinator's office, for DCPs and EWRs, priority drawings are required to be revised prior to test completion, technical review, or operational readiness review as applicable, to be revised within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of the technical review.in Priority all cases priority dra DURs are required to be revised within 15 days of a notification to update following the completion of an engineering review and verification. DURs are a means of informing engineering of drafting and typographical errors or to reflect plant as-built condition Test loop diagrams are required to be updated within 30 days after receipt of a notification to update. Non-priority drawings are required of a notification to be updated within 90 days after receipt to updat The inspectors reviewed selected documents that were affected by the DCPs discussed above and verified that the documents were updated in accordance with the licensee's administrative controls, in addition, the inspectors also reviewed performance indicators which showed that, as of November engineering were issued on time. 30, 1992, drawings issued by The inspectors concluded that the licensee had adequate controls '
for ensuring that applicable documents were updated in a timely manner to reflect the as-built plan .
~ PRA Application in Design Control Discussions with licensee management revealed that the licensee recently completed an IPE for North Anna. The final report was submitted to the NRC by letter dated Decemb9r 14, 1992.

Licensee personnel indicated that the completed PRA is available for use by NES personnel in the design ,
control arocess. The inspectors concluded that the completed PRA i for Norta Anna is another tool that is now available to the design organizatio Use of the PRA should enhance the design control proces . Organization, Staffing, and Training The inspectors reviewed the licensee's organization and staffing to determine whether the licensee's engineering organization was adequately staffed to provide effective engineering support to the plan The Nuclear Engineering organization is comprised of seven departments which report-via managers to the Vice President Nuclear-Engineering Services. This includes the special group established for the steam generator replacement project. Station Engineering is part of NES and reports through the Manager Nuclear Engineering to the Vice President NE Day to day real time support was primarily provided by Station Engineerin The staffing levols within NES have not changed significantly over the-last year. The staffing levels were sufficient to_ support plant activitie The inspectors reviewed variocs performance indicators for selected engineering activities which showed that Engineering provided timely support to the plant during 1992. Drawings which required updating were completed arior to their due dates. Engineering established a goal for tie number of backlogged (greater than 90 days old) minor modifications not to exceed 50. . The backlog was reviewed on a monthly basis. The actual backlog never reached 40 during any month-in 199 CTS items and DRs assigned to Engineering were answered before their due date The inspectors concluded from reviewing the completed DCPs and the
'
various performance indicators that NES:provided adequate and timely -
support to the plant, in addition to reviewing the licensee's organization and staffing,_'the inspectors also reviewed the training provided to the Engineering staffs. Training was provided in accordance with the requirements-
'pecified in the Nuclear Technical Staff and' Technical: Staff Managers'
.
Training Program, Revision 9. The program specifies initial' and
. continuing training requirements for both site and corporate engineering personnel. The training program specifies fundamental training required for all engineers and additional training for the various disciplines, included in the fundamental training is three weeks of systems l training.-
In addition to'the training specified in the program, the inspector noted that engineerfrg personnel receive 10 CFR 50.59 Safety Evaluation

training. The inspectors verified that selected engineers involved in the DCPs discussed in paragraph 2.b. of this report had received 10 CFR 50.59 training within the last year. The inspectors also noted that several of the supervisors and managers in Engineering (site and
'
corporate) have received operations training. Several of the supervisors and managers have either worked in the plant as a SR0 or have SRO certification The inspectors concluded that the licensee's training program for the engineering staff was adequate. The inspectors considered the operations training and experience in NES to be a strengt ;
' Review of Licensee Event Reports (LERs)
-
The inspectors reviewed LERs 91 002 (Unit 1),92-002 (Unit 1),90-005 (Unit 2) and 92-003 (Unit 2). The reports identify certain pressurizer safety valves (PSVs) and main steam safety valves (MSSVs) where the measured lift pressure did not meet the setpoint pressure Technical Specification (TS) limit within +/- one percent. The as found lift pressure was determined by Wyle Laboratory using-steam as a test mediu The licensee concluded that there was no significant safety implications from the high lift pressure setaoint drift since the as found lift t pressure settings were bounded )y the safety analysis for overpressure transients. Specifically, the expected pressure was less-than design basis pressure. Also, there was no significant safety impact for the safety valves where the setpoint drift was on the low side of the setpoint tolerance since the shift did not activate the valves and '
result in a challenge to safety systems. The licensee concluded that the safety valves would have performed their safety functions if require Immediate corrective action was to have the valves refurbished and the setpoints adjusted to meet the TS setpoint limit within +/- one percent *
toleranc The concerns relating to PSV setpoint shif t were identified to licensees in NRC Information Notice (IN) 89 90, Pressurizer Safety Valve Lift .-
Setpoint Shift, and Supplements 1 and 2 to IN 89-90. These notices
. identified a potential problem with pressurizer safety valve lift setpoint shifting related to setting a setpoint with steam-flow and operating the valves with a loop seal filled with wate In letters to the NRC dated December 21, 1990, October 31,-1991,.an November 12, 1992,- the licensee proposed, as.long term resolution to th setpoint drift problem, to drain the loop seals and operate the PSVs in a steam environment as is used'for setting the lift pressure. However, modification of the loop seals has been deferred pending the results of the NRC review of the Westinghouse Owners Group report (WCAP 12910) on pressurizer safety valve setpoint shif . . . . . .

in addition to the above corrective actions, the licensee is considering submittal of a request f or a license amendment to expand the setpoint tolerance. In this regard the licensee is currently reviewing an
analysis and draft license amendment request to change the setpoint tolerance for the MSSVs from 4/- one percent to +/- three percen Since the setpoint 3roblem and corrective action is essentially the same for the four LERs tle inspector considered it appropriate to close LERs91-002 (Unit 1) and 90 005-(Unit 2).
