SUBJECT:
CATAWBA NUCLEAR STATION - NRC EVALUATION OF CHANGES, TESTS, AND EXPERIMENTS AND PERMANENT PLANT MODIFICATIONS INSPECTION REPORT 05000413/2014008 AND 05000414/2014008
Dear Mr. Henderson:
On April 10, 2014, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Catawba Nuclear Station Units 1 and 2, and discussed the results of this inspection with M and other members of your staff. Inspectors documented the results of this inspection in the enclosed inspection report.
The NRC inspectors did not identify any findings or violations of more than minor significance.
In accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding, of the NRC's "Rules of Practice," a copy of this letter, its enclosure, and your response, if any, will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
Sincerely,
/RA/
Rebecca L. Nease, Chief

SUMMARY
Inspection Report (IR) 05000413/2014-008, 05000414/2014-008; 03/24/2014-04/10/2014;
Catawba Nuclear Station, Units 1 and 2; Evaluations of Changes, Tests, and Experiments and Permanent Plant Modifications.
This report covers a two-week, on-site inspection by one senior projects inspector and two reactor inspectors. No findings or violations were identified. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 5.
REPORT DETAILS
REACTOR SAFETY

1R17 Evaluations of Changes, Tests, Experiments and Permanent Plant Modifications
a. Inspection Scope
Evaluations of Changes, Tests, and Experiments: The team reviewed six safety evaluations performed pursuant to Title 10, Code of Federal Regulations (CFR) 50.59 to determine if the evaluations were adequate and that prior NRC approval was obtained as appropriate. The team also reviewed 18 screenings where licensee personnel had determined that a 10 CFR 50.59 evaluation was not necessary. The team reviewed these documents to determine if:
- the changes, tests, or experiments performed were evaluated in accordance with 10 CFR 50.59 and that sufficient documentation existed to confirm that a license amendment was not required;
- the safety issues requiring the changes, tests or experiments were resolved;
- the licensee conclusions for evaluations of changes, tests, or experiments were correct and consistent with 10 CFR 50.59; and
- the design and licensing basis documentation used to support the change was updated to reflect the change.
The team used, in part, Nuclear Energy Institute (NEI) 96-07, Guidelines for 10 CFR 50.59 Implementation, Revision 1, to determine acceptability of the completed evaluations and screenings. The NEI document was endorsed by the NRC in Regulatory Guide 1.187, Guidance for Implementation of 10 CFR 50.59, Changes, Tests, and Experiments, dated November 2000.
This inspection constituted six samples of evaluations and 18 samples of screenings as defined in Inspection Procedure (IP) 71111.17-04.
Permanent Plant Modifications: The team reviewed six permanent plant modifications that had been installed in the plant during the last three years. The modifications reviewed are listed below:
- 0000104610 Optional Reactor Vessel Head Nut Replacement with Hydranuts
- 0000104454 Catawba Dry Storage Project Phase II
- 0000110973 Modify Unit 2 EDG Pre-Position Circuit
- 0000075788 Replace NIS S/R And I/R Instrumentation
- 0000102396 Revise U1 S/G PORVS 1SV7 & 1SV19 Control Power
The modifications were selected based upon risk significance, safety significance, and complexity. The team reviewed the modifications selected to determine if:
- the supporting design and licensing basis documentation was updated;
- the changes were in accordance with the specified design requirements;
- the procedures and training plans affected by the modification had been adequately updated;
- the test documentation as required by the applicable test programs had been updated; and
- post-modification testing adequately verified system operability and/or functionality.
The team also used applicable industry standards to evaluate acceptability of the modifications and performed walkdowns of accessible portions of the modifications.
Documents reviewed are listed in the Attachment.
This inspection constituted six permanent plant modification samples as defined in IP 71111.17-04.
b. Findings
No findings were identified.
4OA6 Meetings, Including Exit
On April 10, 2014, the team presented inspection results to Mr. Henderson and other members of the licensees staff. The team verified that no proprietary information was retained by the inspectors or documented in this report.
