SUBJECT: SOUTH TEXAS PROJECT, UNITS 1 AND 2 - NOTIFICATION OF INSPECTION
(INSPECTION REPORT 05000498/2012002 and 05000499/2012002) AND
REQUEST FOR INFORMATION
Dear Mr. Halpin:
On January 23, 2012, the NRC will begin the on-site portion of the Gas Accumulation
Management in Emergency Core Cooling, Decay Heat Removal, and Containment Spray
Systems Temporary Instruction at your South Texas Project 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 on-site 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 January 16, 2012. Upon review
of these documents, the inspectors will select additional documentation for review upon
arrival. By January 19, 2012, the inspector will communicate the initial selected samples.
- The second group of documents requested is needed to support our on-site inspection
activities. This set of documents should be available to the inspector on January 23, 2012. 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 Robin Savage of your licensing
organization. If there are any questions about this inspection or the material requested, please
contact the inspector, Gerond A. George, at 817-276-6562 or by email at
Gerond.George@nrc.gov.

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 http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

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 Gerond A. George, to facilitate the
selection of specific items that will be reviewed during the on-site inspection week. The inspector
will select specific items from the information requested below and then request from your staff
additional documents needed during the on-site 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 on-site inspection. If you have any questions regarding
this information request, please call the inspector as soon as possible.
