NRC Temporary Instruction 2515/166, PWR Containment Sump Blockage,

Unit 1(Open)

Results for the preliminary inspection of Comanche Peak Steam Electric Station

(CPSES), Unit 2, were documented in Inspection Report 05000446/2006005.

From March 12-14, 2007, the inspector reviewed the licensees implementation of Unit 1

plant modifications and procedure changes committed to in the licensees response to

Generic Letter 2004-02, Potential Impact of Debris Blockage on Emergency

Recirculation During Design Basis Accidents at Pressurized Water Reactors. In

addition, the inspector verified that the changes were reviewed and documented in

accordance with 10 CFR 50.59 processes.

The inspector observed the installation of sump strainers and other physical

modifications in Unit 1. In addition, the inspector reviewed setpoint changes to the

swapover point from the refueling water storage tank to the emergency recirculation

sump. The setpoint changes were approved by NRC before the modification was

completed. Changes to the containment coatings programs, latent debris programs,

and other programmatic changes, as committed, were not completed because of delays

in the final acceptance of test results for chemical and downstream effects.

At the time of the inspection, only 11 of 22 commitments have been fully completed.

Final review and acceptance of chemical and downstream effects will be completed by

the Office of Nuclear Reactor Regulation (NRR) at a later date. Since final acceptance

of the licensees commitments were not complete, the inspector evaluated the

recirculation sump modifications to the original design basis, Regulatory Guide 1.82,

Revision 0, ?Water Sources for Long-Term Recirculation Cooling Following a Loss-of-

Coolant Accident. Pending final submittal and acceptance of licensees commitments

to Generic Letter 2004-02. Temporary Instruction 166 for CPSES Units 1 and 2 will

remain open.

4OA6 Exit Meeting Summary

The inspector presented the inspection results of Temporary Instruction 2515/166 to

Mr. R. Flores, Site Vice President, and other members of the licensees management

staff at a pre-exit interview on March 14, 2007. The licensee's management

acknowledged the findings and observations presented. The inspector communicated

to the licensees management that a final exit will occur at a later date pending NRRs

final acceptance of the licensees commitments to Generic Letter 2004-02. In addition,

the inspector asked the licensee's management whether any materials examined during

the inspection should be considered proprietary. No proprietary information was

identified.
