The space below each of the following questions may be used to record the results ofjudgments and findings.Additional space is provided at the end of this checklist for documenting other comments.l. Does anchorage of equipment in the area appear to be free of potentially adverse seismic conditions (if visible without necessarilyopening cabinets)?2. Does anchorage of equipment in the area appear to be free of significantdegraded conditions?

3. Based on a visual inspection from the floor, do the cable/conduit raceways and HVAC ducting appear to be free of potentially adverse seismic conditions (e.g., condition of supports is adequate and fill conditions of cable trays appear to be inside acceptable limits)?4. Does it appear that the area is free of potentially adverse seismic spatial interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

Blockwalls SBI-7 and SBl-8 are adequate based on Calculations DSC-0086 and DSC-0087, respectively. Blockwall SBI-10 is adequate based on calculation DSC-0089_1. These calculations are part of afollow-up seismic analysis in support of IE80-11calculations. All blockwalls in area are adequate.

Two valves with reach rods through the wall are on the supply piping to pump CH-P-IC. The gap at the wall penetration around each rod is approximately 1". The supply piping does not have lateral support and its potential movement in a seismic event could close the gap at reach rod wall penetration and cause binding. Judged acceptable, as the pipe goes through a ceiling penetration, which would provide some restraint, as well as thefact that the valves sre manual valves with reach rods and that potential reach rod binding would be acceptable.

Several unrestrainedfire extinguishers in the area. Since the vertical accelerations in this area are well below Ig, it is judged that these extinguishers would not dislodge from their wall supports, and therefore the interaction is not credible.

8. Have you looked for and found no other seismic conditions that couldadversely affect the safety functions of the equipment in the area?Soot on ceiling indicates possible exhaust leak. A follow up with plant personnel has revealed that the soot is caused by a downdraft that naturally occurs on the roof leading to the deposit.

Does it appear that the area is free of potentially adverse seismic spatial interactions with other equipment in the area (e.g., ceiling tiles and lighting)?A damaged pipe insulation near valve MOV-IMS-LlS was judged to be due to servicing of the valve and not a seismic concern.

A pipe connected to a containment penetration 89 (valve TV-ISV-100A is on this pipe) has a gap of I/8" to a knee bracemounted on Safeguards Building. The effect of dffirential building displacements atthis elevation between the two buildings was investigated and./bund that the pipe has adequateflexibility to accommodate the demand seismic displacements of the two buildings.

Thespace below each of the following questions may be used to record the results ofjudgments and findings.Additional space is provided at the end of this checklist for documenting other comments.l. Does anchorage of equipment in the area appear to be free of potentially adverse seismic conditions (if visible without necessarilyopening cabinets)? Small gap under base of one of the saddles of heat exchanger FC-E-lB judged not bean issue of concern.2. Does anchorage of equipment in the area appear to be free of significant degraded conditions?

3. Based on a visual inspection from the floor, do the cable/conduit raceways and HVAC ducting appear to be free of potentially adverseseismic conditions (e.g., condition of supports is adequate and fill conditions of cable trays appear to be inside acceptable limits)?4. Does it appear that the area is free of potentially adverse seismic spatial interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

Temp. gage Tl-IFC-1028 is on a 6" diam. nozzle out of HX FC-E-18. There is a gap of -3/16" between this temp. gage and rigid HVAC support. It is judged that the nozzle piping and HVAC support would not displace by 3/16" in a seismic event andthis interaction is not credible.

Does it appear that the area is free of potentially adverse seismicinteractions that could cause flooding or spray in the arca?A space heater and its attached piping in the area are rod hung. Displacement of this heater in a seismic event would cause an interaction between its inlet piping andnearby large diameter pipe, which could potentially cause spray concern in the area.Lighting transformer LTG-TFMR-F2 and lighting panel AC-LTG-PNL-F2 are judged to be outside of the spray zone of this piping and judged acceptable. AIso, noflooding concern for this area is identified.

6. Does it appear that the area is free of potentially adverse seismicinteractions that could cause a fire in the area?7. Does it appear that the area is free of potentially adverse seismic interactions associated with housekeeping practices, storage of portable equipment, and temporary installations (e. g., scaffolding, lead shielding)?Unsecuredfire extinguisher and posts do not pose seismic interactions. Scaffold inarea is judged acceptable.8. Have you looked for and found no other seismic conditions that couldadversely affect the safety functions of the equipment in the area?One of ten bolts connecting the bonnet of manual valve ICCR-106 to its body does nothavefull thread engagement (approximately one-half thread is not engaged).

Judgedacceptable, as the valve is very light and has a very low moment arm. Similar threadengogement issue observed at Valve FC-E-18 and judged acceptable as-ls.

NRC Safety Evaluation for USI A-46 Program Implementation at BV-1, letter dated December 9, 1998 (fAC No. M69428)This letter provides the Beaver Valley Power Station Unit I (BV-t) completion reportfor tlre closure of Generic Letter (GL) 87-02, "Verification of Seismic Adequacy of Mechanical and Elecrical Equipment in Operating Reactors, IJnresolved Safety lssue (USD 4-46" as required by the Seismic Qualification Utility Group (SQUG) program.The Completion Report (Attachment l) provides the final resolution of specific items identified in References I through 3. The Updated Outlier Resolution Tabulation (Attachment

2) provides the final resolution of the outliers identified in Reference l.

Attachments I and 2 identiS those outliers for which the probable resolution option wasnot originally identi{ied in References I through 3 or a different option was chosen during the resolution process. For those other outliers (not listed in Attachments I and2), the resolufion implemented was as previously described. The relay tabulation portionof Attachment 2 includes the resolutions for all of the relays identified in Reference l,and is included for information due to changes in some of the relays' stahrs from essential to non-essential. Beaver Valley Power Station, Unit No. l" Completion Report for Generic Letter 87-02, USI A-46 Program L-04-492 Page 2 Where outlier resolution involved the use of the seismic experience database beyond that which the NRC had previously approved for the Generic Implementing Procedure (GIP), the NRC's SSER-Z on the GIP required submittal of such data to the NRC. Therefore, Attachment 3 provides an analysis of the experience database to identiff damper configurations that were subject to earthquake input that exceeded anticipated BV-l seismic levels, without detrimental effect. Since the BV- I dampers have similarconfigurations to the dampers that have been found to seismically perform their intended firnction, they are considered seismically acceptable. The NRC was informed of BV-l'sintent to address damper outliers in this manner in Reference L, Section 5.3.1.4.Attachment 4 provides the analysis for over-sized panels, in which BV- l sommitted tosubmit to the NRC as an outlier resolution in Reference 2.Referense 4 documented the NRC's safety evaluation regardiirg USI A-46 program implementation at BV-l and closed the USI A-46 review for BV-I. With the submittalof this completion report in accordance with the SQUG program, FirstEnerg,y Nuclear Operating Company (FENOC) considers USI /*46 resolved for BV-l.If there are any questions concerning this completion report, please contact Mr. T.

Section 5.3.1.5 and Reference 3. Item I - Loss of air supply to seven (7)essential Air-Operated Valves (AOV) requires operator action. The procedural pidancefor required operator action was reviewed and found to be adeguate for the affectedvalves. Ilowever; to minirnize the efrect of having the oharging flow control AOV failopen, a procedure was revised to have the operator use associated manual valves tocontrol flow. Since charging will increase pressurizer level until letdovm can be esteblished, procedural guidance to allow a 75% pressurizer maximum level prior toboration was added.2. Reference 1. Sectioas 5.3.1.8 & 5.3.1.9 - Consfiuction joints in the floor near equipment anchors were treated as free-edges under SQUG criteria" reducing bolt capacity to z'ero.Analysis of the components involved showed that no uplift existed on the affectedanchors. Therefore, joint effects were inconsequential. In addition" rebar scanning proved that reinforcing steel was, in fact, continuous through the joint, which would make the concrete effective for pullout loads were they to occur. The anchors also had Quality Control markings indicating successfirl tension testing at installatioa.3. Reference 2. Iteln 2 - The calculation of tank deflection proved ttat an "abandoned sEut" (tubing tra, that touches the insulation on tank CH-TK-IA is not atr interaction concern;thercfore, it was not removed.4. Reference 2. Item 4.g - As noted in the RAI response, the AMSAC panel containing a programmable recorder could have been evaluated using a new equipment criteriadeveloped by SQUG. As an alternative, the equipment was reviewed to up-rate its qualigcategory assignment The equipment was originally seismically qualified by ib supplier 3.4. Attachment I Generic I*tter 87-02, USI A-46 Completion Report Page2to IEEE 344-75 standards. Only minor modifications were necessary to bring the installed configuration into compliance with the tested configuration. Since the equipment meets current seismic standards, the application ofthe supplemental SQUG data was not needed.5. Rderence 2. Item 4.h - The over-sized heater panels qpecific to this item are essentially empty, but have at least one dimension that exceeds the curent SQUG crit*ria linits.This outlier condition q<isted for sweral other panels as well. Since ample representationof larger panel sizes exists in the experience database, fhese outliers were resolved by an EQE comparative analysis (included as Attacbment 4). this analysis establishes thrt there is essentially no history of large panel failure. Consequently, the dimensions of these panels are not critical characteristics and the insalled configurations arc acceptable.6. Reference 2. Item 4.1 - Dampers do not currently have specific acc*ptance criteria rmder GIP guidelines. EQE Intemational developed supplemenal damper database acoeptrnce criteria and performed an analysis for applicability to BV-l. This analysis is provided as Attachment 3 and confirms that the BV-l dampers are seismically acceptable.

7. Reference 2.

Jtem 4.m - A damper operrtor had interactim conoenu that could potentiallyhave required a conduit to be rclocated. The damper's axle rod extends at a right aoglebeneath" and touolies, a conduit mounted directly to the ceiling slab above. Further rwiewof the geometry involved concluded ftat the conduit touching the damper's axle at a single point cannot restrict motion of the axle since the ade's only motioo is rotation" which it can presently perform. Both the damper and conduit are anchored directly to the ceiling, with essentially no possible relative seismic displacement that could produce detimental interaction. Therefore, ns rnsdificatign was necessary lo resolve this oudier.

8. Refermce 2. Item 5 and Reference 3. Item 6 - Opoator training.

Tbree (3) simulations of a plant strutdowq with all but SQUG equipment disable4 were nm druing the course of SQUG development and implementation. The need for additional operator taining in thisarea was evaluated and did not warrant additional training at this timc.9. Reference 3. Ircm 3 - Resetting 'Bad Actor' relays that trip. Operator actions to reset'Bad Actor' relays have not been credited as a means of outlier resolution. Athchment 2 Updated Outlier Comoletion Sabulrtion

This assessment examines the risk associated with external initiating events and buifds on the PRA modeling cornpleted forthe lPE. Like the lPE, this analysis is a level 2 anafysis using state of the art fnethod$.This report constitutes the Beaver Vatley Unit 1 tndividual Plant Exarnination for External Hvents 0PEEE, subrnittal and is organized in accordance with the reporting guidelines of NUREG 1407.Duquesne Light Company utilized the experience gained through preparation of the IPE to perform an update of the PFA model for Beaver Valley Unit 1 to incorporate plant changes rnade since the IPE was completed and update cornponent failure frequencies based on rnore recent plant specific data. DLC Farticipated in alf aspects of the IPEEE including coordination of all plant walkdowns, integration of the seismic and fire models into thePRA model, and sequence guantification. The results of this evaluation indicate that the overall CDF early release frequencies associated with external events is consistent with the results of studies performed for other plants and therefore, no specific vulnerabilities have been identified for Beaver Valfey Unit 1. Examination of key contributors from the seismic and fire evaluations indicates the following:. The most risk significant component for seismic initiating events is the block walls which enclose the station batteries. Afthough the high confidence - low probability of failure (HCLPF) velue is above the SSE value for the site, failure at higher g values is assumed to result in a loss of 'both sets of emergency DC control power and eventual core damage.c { high percentage of the CDF due to fire initiating events results from equipment impacts which are a direct result of the,fire without additional failures.n Much of the fire-initiated CDF results from fires which result in a loss of both trains of river water. These $equences lead to a loss of RCP seal cooling resulting from a loss of cornponent cooling and RCP seal iniection. Eventual seal failure results in a seal LOCA.Other external *vents such as high winds and tornadoes, external floods, and transportation and nearby facilities contribute an insignificant arnount to overall CDF.The evaluation has also provided an increased understanding and appreciation of the importance of certain recovery procedures which have been credited primarily in thF evaluation of key fire subscenarios. The procedures identified include specific alternate shutdown procedures lor varlous fire locations, emergency operating procedures, and response procedures for specific equipment failures.8-1 9e_aver Valley' fower.iStation Unit I'Probabilistic RiSk Assessment tlPEEEl Revision O Evaluation of keyi contributors indicates common elements with respect to those identified in the tPE. A high percentage of sequences leading to core damage are the result of a lossof RCP seal'injectio4 and thermal barner cooling resulting in a seal LOCA. These sequences primarily involve a direct loss of both trains of river water or a loss of all ACresulting from a loss of switchgear ventilation. No specific vulnerabilities due to external initiating events have been identified as a result of this study for Beaver Valley Unit 1 . DLC considered potential enhdnsements associatedwith key CDF contributors as listed in Section 7.2. Based on the low contribution to overall-linternal plus externall CDF, no rnodificatlons or additional analyses are planned at this time, DLC will continue to utilize the PRA model developed to evaluate the risk reduetion benefits of other potential enhancements which may be considered in the future. Resolution of Unresolved Safety lssues and Generic lssues has been addressed in Sections3 and 4 of this.report. fncluded are discussions-relative to USI A-45, 'Shutdown Decay Heat Removal Requirements"; NUREG/CR-5O88, "Fire Risk Scoping $tudy"; Gl-57, nEffects of Fire Protection System Actuation on Safety-Related Equlprnent"; and Gl-131,"Potential $eismic Interactions Involving the Movable ln-Core Flux Mapping $ystem Used in Westinghouse Plants." In conclusion, DLC has continued to develop and utilize PRA technology through this evaluation 'of external events and comptetion of an update of the PRA models utilized in the IPE for Beaver Vatley Unit 1 . The insights gained and techniques developed will continue to be utilized as part of a risk rnanagement prograrn to support.safe operation: 8,-2}}
