CPNPP GSI-191 Closure February 28, 2013 1
Purpose of the Meeting
- To open plant specific discussions with the NRC regarding strainer testing The licensee will discuss the Generic Safety Issue 191 (GSI-191) pump strainer test protocols for bypass and head loss testing and related topics for Comanche Peak Nuclear Power Plant, Units 1 andd 2.
2 The Th licensee li is i considering id i a repeatt h headd lloss ttestt tto include newly identified debris source (fiberglass tape) and would like to discuss the data extrapolation methods from previous testingg to determine if the additional testing g is needed.

Background
[ML093080003/ML093080004]
- Alden Labs Prototype Strainer Flume Testing Testing, March 2006
- Alion Science and Technology Debris Transport Testing, August 2006
- Alden Labs Strainer Flume Testing, March 2008
- NRC Letter dated April 1919, 2010 [ML100950564]
- The NRC staff has no further questions for CPNPP, Units 1 and 2, at this time regarding completion of corrective actions or GL 2004-02. This conclusion is based on the staff's evaluation of your submittals, with emphasis on your responses to an NRC staff request for additional information dated July 15, 2009.

RESOLUTION, February 13, 2012
- Plant Specific Decisions and Hold Points
- CPNPP is evaluating bypass testing in a tank versus a flume
- Contingent on a suitable test protocol and appropriate precedent 4
Comparison to Recent Testing
- Strainer Bypass Test Protocol - Tank Test Precedents
- MHI (minimal fiber, LDFG)
- Strainer B Bypass pass Test Protocol - Flume Fl me Test Precedent
- Point Beach (Nukon, LDFG, Mineral wool, Cal-Sil, Asbestos)
- CPNPP Plant specific p debris issues ((lead blanket covers and Glass 69 tape
- Lead blanket covers were included in previous testing
- Glass 69 tape has not been tested (discovered after previous testing)
- Similar to tapes and lead blanket cover materials previously tested
- Quantity is much less than previously tested materials 5
Fibrous Debris
- Latent Fiber (surrogate - treated as Nukon)
- Low Density Fiber Glass (surrogate - treated as Nukon)

Head Loss
- The extrapolated debris head loss for 30 days (T=2,592,000 sec) using the exponential curve fit is 0.7497 ft of water
- The maximum total strainer head loss due to the design basis debris load extrapolated to 30 days at 212 °F F is 1.55 1 55 feet feet.
- This extrapolation showed a conservative minimum NPSHa margin of 5 feet at 30 days.
- Transport testing of intact tapes and labels showed settling before the strainer.
- Head loss testing assumed 200 sq. ft. of blocked strainer (approx.
5%)

Gl Glass 69 Tape T Scotch S t h 69 Gl Glass Cloth Electrical Tape is a white glass tape with a high temperature thermosetting silicone adhesive 15
Glass 69 Tape
- There are similarities between the Glass 69 tape and the blanket covers ((e.g.
g embedded fiber in chemical and temperature p
resistance materials)
- Comanche Peak is considering using the same debris preparation method for the Glass 69 tape as was used for the blanket covers
- An alternative could be to use an equivalent quantity of Nulkon as a surrogate for the tape
- Transport testing for blockage and head loss could be performed separately or as part of an integrated head loss test 16
Options
- Perform Bypass Testing in a Tank
- Plant specific debris issues
- Protocols critical to acceptable results
- Separate transport testing required for Glass 69 tape
- Perform Bypass Testing in a Flume
- Understood U d t d protocol,t l prior i experience, i iissues addressed.
dd d
- Would include transport p and head loss testing g of Glass 69 tape
- . Questions and/or Comments?
