Request for Additional Information (RAI) - Donald C.Cook Nuclear Plant Units and 2 - LAR to Revise TS 5.5.14 - Containment Integrated Leak Rate Testing - MF3568/69 By letter dated March 7, 2014 (ADAMS Accession No. ML14071A419), as supplemented by letters dated September 30, 2014 (ADAMS Accession No. ML14275A454), December 16, 2014 (ADAMS Accession No. ML14352A232), and January 15, 2015 (ADAMS Accession No. ML15020A662), Indiana Michigan Power Company (I&M, or the licensee), submitted a license amendment request (LAR) for a permanent extension to the Type A (Integrated Leak Rate Test (ILRT)) and Type C (isolation valve Local Leakage Rate Test) by revising Technical Specification (TS) 5.5.14, for Donald C. Cook Nuclear Plant (CNP) Units 1 and 2. The proposed change would permit the existing Containment Integrated Leak Rate Testing (ILRT) (Type A) frequency to be extended from 10 years to 15 years and Type C testing frequency to be extended up to 75 months on a permanent basis.
The Nuclear Regulatory Commission (NRC) staff has reviewed the LAR and has identified areas where additional information is needed to complete its review. There are two sets of RAIs here. The first RAI is from Containment and Ventilation Branch (SCVB) and the second RAI is from probabilistic risk assessments (PRA) licensing branch (APLA).
SCVB-RAI-1 In the licensees submittal (March 7, 2014) it states, in section 4.3 Type B and Type C Testing Programs, that U2C20 As-Found Minimum Pathway Leakage Rate had exceed the TS performance criterion value of 0.6 La (66,131 sccm) for the combined Type B and Type C test as found minimum pathway total. The reasoning given was that:
In that case, an evaluation was conducted and work was performed to replace the hinge ring retaining dowel pins which were determined to be too short.
The staff would like additional information regarding:
a) The as-found minimum pathway leakage rate for U2C20 (April 2012).
b) The component that resulted in the exceeding the combined Type B and Type C leakage TS value of (66,131 sccm).
c) Whether the containment past operability had been determined; if so, please explain the basis for the conclusion.
d) Whether this component falls under the Containment Maintenance Rule function (10 CFR. 50.65) and if so what impact did the failure have.
e) The components previous failures, if any, and any actions taken to prevent recurrence.
APLA RAI-1 In response to the request for additional information dated January 15, 2015 (ADAMS Accession No. ML15020A662), I&M performed an assessment of the PRA against the PRA standard ASME RA-Sa-2003 and indicated that eleven supporting requirements (SR) were determined to not be met at the Capability Category (CC) I level according to the 2003 ASME PRA Standard.

- a. I&M provided justification of no impact for ten of the eleven SRs not met at CC I level. Clarify if there are any missing requirements not listed in the RAI response that do not meet CC I and, if so, justify why not meeting each CC I requirement will have no impact on the ILRT extension application.
- b. If PRA is assessed against Revision 2 of Regulatory Guide (RG) 1.200 and the 2009 PRA standard ASME/ANS RA-Sa-2009, explain whether there are any additional SRs that are not met at CC I level that would impact the ILRT extension application.
Please arrange a teleconference to discuss the above requested information with the NRC staff. Thanks Mahesh Chawla Project Manager Phone: 301-415-8371 Fax: 301-415-1222 mahesh.chawla@nrc.gov 2
