V.C. Summer Station Recirculation Sump Design Changes Kirk Weir Design Engineering
Overview
Analysis Results
- ~930ft2 strainer for each train
- 8.2 ft3 fiber load on the sump
- 1.5 ft3 tempmat
- 6.7 ft3 latent fiber (105 lbs latent debris)
- 190 ft2 unqualified tape, placards, stickers
- Chemical Effects account for <1%
total particulate
- Marinite insulation is not a problem
Analysis Results
- 713.7 ft3 of RMI (mirror insulation) debris
- 27.3 ft3 transports to the sump
- based on RMI debris transport testing
- removed the need for debris interceptors
Analysis Results
- Evaluation of sump level for break inside the primary shield was completed and is acceptable
- Evaluation of sump level for break inside the pressurizer cubicle was completed and is acceptable. the pressurizer cubicle door latching mechanism is assumed to fail.
- HHSI throttle valves will be replaced due to downstream effects
- current valve opening is 1/32
- new valve opening is ~3/32
Ongoing Analysis Work
- Cumulative effects program -
calculations are being completed and procedure updates are prepared
- Evaluation of downstream effects
- Conducting large scale testing on strainers
RF-16 Modifications
- Complete recirculation sump strainer replacement
- 2400 ft2 per train
- RHR and spray pump strainers cross-tie
- Block southern stairwell of 436 ft elevation
- Remove toe-kick plate on 436 ft elevation
- Installation of new HHSI throttle valves
AECL Strainer Designs
Review
- On track to meet the requirements of the Generic Letter
- Supplemental response to Generic Letter by 12/31/06
- Major modifications planned for RF16
