NOTIFICATION OF INSPECTION (NRC INSPECTION REPORT
05000445/2011004; 05000446/2011004) AND REQUEST FOR INFORMATION
Dear Mr. Flores:
On August 15, 2011, the U.S. Nuclear Regulatory Commission (NRC) will begin the onsite
portion of the Gas Accumulation Management in Emergency Core Cooling, Decay Heat
Removal, and Containment Spray Systems Temporary Instruction at your Comanche Peak
Nuclear Power Plant, Units 1 and 2. This inspection will be performed in accordance with NRC
Temporary Instruction (TI) 2515/177.
Experience has shown that this inspection is resource intensive both for the NRC inspectors
and your staff. In order to minimize the impact to your onsite resources and to ensure a
productive inspection, we have enclosed a request for documents needed for this inspection.
The documents have been divided into two groups.
- The first group lists information necessary for our initial inspection scoping and in-office
preparation activities. This information should be separated by information request number,
especially if provided electronically (e.g., folder with the information request number). This
information should be available to the inspector no later than August 1, 2011. Upon review of
these documents, the inspectors will select additional documentation for review upon arrival.
By August 10, 2011, the inspector will communicate the initial selected samples.
- The second group of documents requested is needed to support our onsite inspection
activities. This set of documents should be available to the inspector on August 15, 2011. It
is also requested that corrective action documents and responses to questions developed
during the inspection be provided to the inspector as the documents are generated.
We have discussed the schedule for these inspection activities with your staff and understand
that our regulatory contact for this inspection will be Gary Merka of your licensing organization.
If there are any questions about this inspection or the materia! requested, please contact the
inspector, Matt Young, at 817-276-6545 or by email at '-'-==:.J:-==~=~='

I. Information Requested By August 1, 2011
1. List of corrective action program documents (with a short description) associated with
Generic Letter (GL) 2008-01, voids in piping, and pressure transients for the previous
three years.
2. List of changes (with a short description and tracking number) to the final safety analysis
report (FSAR), technical specifications, technical specification bases, and technical
requirements manual associated with the resolution of GL 2008-01.
3. List of calculations associated with GL 2008-01, including calculations that have been
changed or created in response to GL 2008-01 (with a short description of the
calculation and the change).
4. List (with a short description) of gas intrusion mechanisms that apply to the plant and the
affected system locations (e.g. identify the source, conditions, and expected void
locations).
5. List of the suction piping sections identified as susceptible to gas accumulation (the list
should identify the corresponding system).

6. List of the discharge piping sections identified as susceptible to gas accumulation (the
list should identify the corresponding system).
7. Copies of isometric drawings of the emergency core cooling, residual heat removal, and
containment spray systems (hard-copies are preferred).
8. Copies of piping and instrumentation diagrams (P&IDs) of the emergency core cooling,
residual heat removal, and containment spray systems (hard-copies are preferred).
9. Copies of program documents and procedures developed to implement the resolution of
GL 2008-01.
10. List of actions that were completed in response to GL 2008-01.
11. Copies of the modification packages for hardware modifications as part of the resolution
of GL 2008-01.
12. Design basis documents of the emergency core cooling, residual heat removal, and
containment spray systems.
13. Design basis documents of keep-full systems of the emergency core cooling, residual
heat removal, and containment spray systems.
14. System walkdown reports associated with the resolution of GL 2008-01.
15. If applicable, provide a list of inaccessible locations where plant walkdowns of the
emergency core cooling, residual heat removal, and containment spray systems have
not been completed. Include an explanation of why each area is considered
inaccessible.
16. Copies of surveillance procedures associated with the resolution of GL 2008-01 and the
results of the last two surveillances for the emergency core cooling, residual heat
removal, and containment spray systems.
17. Copies of procedures used for detecting and determining void volumes.
18. Copies of procedures used for filling and venting.
19. Copies of trends of periodic venting results.
20. Copies of the engineering evaluations performed for all identified voids in the past three
years.
21. Basis for the void acceptance criteria (e.g. calculation). If applicable, provide the
justification for any deviation from the void acceptance criteria established by the Office
of Nuclear Reactor Regulation (NRR).
22. Copy of any void transport analyses.
