UNITED STATES NUCLEAR REGULATORY
COMMISSION
REGION IV Rafael Flores, Senior Vice President
and Chief Nuclear Officer Luminant Generation
Company LLC Comanche Peak Nuclear Power Plant P.O. Box 1002 Glen Rose, TX 76043 612 EAST LAMAR BLVD, SUITE 400 ARLINGTON, TEXAS 76011-4125
June 30, 2011 SUBJECT: COMANCHE PEAK NUCLEAR POWER PLANT, UNITS 1 AND 2 -NOTIFICATION
OF INSPECTION (NRC INSPECTION
REPORT 05000445/2011004;
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
-2 -This letter does not contain new or amended information
collection
requirements
subject to the Paperwork
Reduction
Act of 1995 (44 U.S.C. 3501 et seq.). Existing information
collection
requirements
were approved by the Office of Management
and Budget, control number 3150-0011.
The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information
or an information
collection
requirement
unless the requesting
document displays a currently
valid Office of Management
and Budget control number. In accordance
with Code of Federal Regulations, Title 10, Part 2.390 of the NRC's Rules of Practice, a copy of this letter and its enclosure
will be available
electronically
for public inspection
in the NRC Public Document Room or from the Publicly Available
Records (PARS) component
of NRC's document system (ADAMS). ADAMS is accessible
from the NRC Web site at (the Public Electronic
Reading Room). Dockets: 50-445; 50-446 Licenses:

The following
information
should be sent to the Region IV office in hard copy or electronic
format (ims.certrec.com
or compact disc, preferred), in care of Matt Young, to facilitate
the selection
of specific items that will be reviewed during the onsite inspection
week. The inspector
will select specific items from the information
requested
below and then request from your staff additional
documents
needed during the onsite inspection
weeks. Also, we request that you categorize
the documents
in your response with the numbered list below. Please provide requested
documentation
electronically
if possible.
If requested
documents
are large and only hard copy formats are available, please inform the inspector(s), and provide subject documentation
during the first day of the onsite inspection.
If you have any questions
regarding
this information
request, please call the inspector
as soon as possible.
I. Information
Requested
