MEETING SUMMARY - SURRY PLANT WALKDOWN

June 25 and 26, 1996

Surry Nuclear Power Plant

On June 25 and 26, 1996, Virginia Power performed a walkdown of its Surry Unit 1 Nuclear Power Plant. This walkdown is part of the NEI/ASME/WOG methods development for risk-informed inservice inspection programs (RI-ISI). The purpose of the walkdown was to identify potential indirect effects/consequences from postulated pipe failures, and to identify indirect effects that would differentiate piping into different segments used in the analysis. ·

Syed Ali (NRR), Jack Guttmann (RES) and Donnie Whitehead (SNL contractor) observed the licensee's implementation of the walkdown.

In preparation for the walkdown, the licensee reviewed its:

a. IPE internll flooding analyses b. Pipe whip/jet impingement evaluations on record, Environmental and

dynamic effects design basis (FSAR) c. Appendix R safe shutdown analyses d. General arrangement and piping drawings

The licensee reviewed documents relatedito its existing Section XI ISI programs. The licensee identified systems/trains that could be affected break, it identified plant areas for plant walkdown, and it devel-0ped standardized walkdown sheets to ensure evaluation consistency (see Attachments).

The licensee stated that it performed a detailed evaluation of the consequences of floods originating in and capable of propagating from the turbine building and safeguards areas. The source of flooding identified

~\1\)~

by a

• 2

those areas were the component water system, the service water system, and the emergency safety injection water system. In addition, the licensee stated that it performed a detailed analysis of the consequences of floods originating from the RWST and fire protection system in the auxiliary building.

The areas identified for plant walkdown were:

main steam valve house charging pump cubicles service building turbine building auxiliary building near the elevator and the boric acid storage tanks

The licensee screened out the following areas from inspection based on the lack of a credible flood source in the area or low potential contribution to core damage frequency:

Diesel Generator Room Control Room Emergency Switchgear Room Cable Spreading Room Battery Room Normal Switchgear Room

Flooding that originated in containment were screened out based on the following considerations:

Consequences of failure of piping elements in most fluid systems in the containment building are bounded by that analyzed in the internal events analysis. All PRA-credited, flood susceptible, equipment in the area are qualified for a LOCA environment.

The licensee stated that it was going to verify its conclusions using its computerized imaging system. During the time of the walkdown, Unit 1 was in

· operation and the containment was inaccessible for walkdown purposes.

The licensee defined high energy lines as those operating above 200 degrees F and whose pressure exceeded 275 psig. The systems satisfying the above criteria were:

main steam line main and auxiliary feedwater lines high pressure heater drains and vents moisture separator drains auxiliary steam condensate low pressure heater drains and vents boron recovery

'. ' .• .... •

liquid waste chemical volume control system safety injection steam generator blowdown system extraction steam sample

3

Of the above listed high energy lines, the following are included in the current Section XI ISI program:

main steam lines main/auxiliary feedwater lines condensate chemical volume control system safety injection steam generator blowdown.

When performing the walkdown, the following criteria were used to assess the location of possible pipe breaks:

circumferential breaks in pipes greater than 111 at terminal ends, fitting welds, branch connections

longitudinal breaks in piping systems 411 and larger at welded attachments such as lugs and stanchions

Pipe whip initial hinge distance is calculated by an energy balance technique based on:

thrust force pipe plastic moment pipe concentrated mass at rupture point pipe mass per unit length

Jet impingement loads are a function of: system stagnation pressure jet thrust coefficient break opening area fraction of jet intercepted by target target shape factor jet impingement angle factor

Following the walkdown, the licensee executed post-walkdown technical discussions. It appeared that in most areas the postulated pipe rupture would disable the equipment within the confined quarters. The licensee was going to perform additional pipe whip analyses to assess the potential for secondary failures and the effects of certain check valve alignments (in the charging pump cubicals) to assess the possibility of draining the RWST. The auxiliary

.steam and steam drain lines are not within the scope of Section XI. However, the potential for affecting the component cooling water pumps (potential of pipe whip severing power lines to the pumps) required additional analyses. In parallel, the licensee's PRA group would perform an analysis to assess the

• e 4

risk significance of losing the CCW pumps.

The results of the analyses will be documented in the licensee's submittal.

The next milestone for the RI-ISi program is scheduled for July 31, 1996 at Richmond. At that meeting, input to the SRRA failure analysis code will undergo internal review. The NRC intends to observe that meeting.

On August 6 and 7, the NRC, the ASME, and the licensee will me~t at Portland Oregon to discuss the equations used by the SRRA computer code and compare NRC/SNL independent evaluations of the reactor coolant system with the analyses performed by the licensee.

Notes:

1. If no potential hazard 11 identified, state none.

2. Due to the existence of numerous openinga, water accumulation in this section of the AB is not possible. Hence, flood-induced damage to the equipment located in this section is not credible. However, floods originating from components located here will propagate to the 2' elevation and can potentially cause significant damage.
