Introduction Reason for Commitment Change
" Management Challenge
- Design Change Package late issue
- Planning & Scheduling not timely
- Implementation Resources
" Risk of implementing Design Change
- Risk of impact to SW supply to RBCU function without corresponding risk improvement from design change Plant Safety in Current Configuration VCSNS will remain safe:
- Water hammer condition exists only when SW aligned to RBCU's and LOOP
- Becomes significant only when SW aligned to RBCU's, w/LOOP, and w/LOCA or MSLB
- PRA indicates very low risk (1.74E-07/yr)
- Phase 1 actions in place
- No damage to piping or hangers Enclosure 2
I Schedule for Design Change Implementation (Commitment change required)
Implementation by 5/2008 (Refueling 17)
- Extensive modification
- Unit shutdown required
- Next scheduled shutdown for refueling Resolution of Technical Issues from NRC letter August 22, 2006
" VCSNS reviewed NRC ltr. dated 8/22/2006
" No additional explanation necessary
" VCSNS expects to respond in the next 60 days
Introduction Purpose of Visit
" Discuss VCSNS commitments associated with Generic Letter (GL) 96-06.
- Implement design changes by 10/06
- 1. Delay opening 3107A/B
- 2. Install vacuum relief valves
- 3. Replace 3107AJB

- Plant Safety in Current Configuration
- Schedule for Implementation of Modifications
- Resolution of Technical Issues
NRC/VCSNS Open Discussion FIGURE 2a Modification Inital Configuration - RBCUs aligned with SW system 3109A WATER HAMMER MITIGATION - Mod to install: XAA-1
- 1. vacuum relief valve downstream of 3107A
- 2. replace 3107A with an air operated butterfly valve that fast closes upon de-energize ofSWBP 3108B 3109B
- 3. delay opening of valve 3107A for five seconds after start of SWBP XAA-I B Lý PHASE 1 - LOOP occurs causing SW booster pumps to de-energize.
Fast closing valve PHASE 2 - Valve 3107A fast closes and traps traps water above it Column of fluid above it PHASE 3 - Void formed below 3107A is filled with air by vacuum relief valves PHASE 4 - After 41 seconds, SW Vacuum booster pumps re-energized, 3107A valve 5 sec Relief delayed opening allows fluid flow momentum to Valve build preventing further void formation PHASE 5 - air void downstream 3107A flushed to SW pond
