Subject:
Revision to License Amendment Request to Update the American Society of Mechanical Engineers Code Referenced in Technical Specification Section 5.5.6, Inservice Testing Program Cooper Nuclear Station, Docket No. 50-298, DPR-46
Reference:
Letter from Randall K. Edington, Nebraska Public Power District, to U.S.
Nuclear Regulatory Commission, dated March 7, 2006, "License Amendment Request to Update the American Society of Mechanical Engineers Code Referenced in TS Section 5.5.6, Inservice Testing Program" The purpose of this letter is to submit a revision to the license amendment request (LAR) submitted by the Nebraska Public Power District (NPPD) by letter dated March 7, 2006 (Reference). That LAR submitted a proposed revision to Cooper Nuclear Station (CNS)
Technical Specification (TS) Section 5.5.6, "Inservice Testing Program." The proposed revision would revise the referenced code from Section XI of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code to the ASME Code for Operation and Maintenance of Nuclear Power Plants, and extend the applicability of TS Surveillance Requirement (SR) 3.0.2 provisions to other normal and accelerated frequencies specified in the Inservice Testing (IST) Program. TS SR 3.0.2 allows a delay of 25 percent of the specified frequency in performing a surveillance.
The U.S. Nuclear Regulatory Commission (NRC) Project Manager for CNS informed NPPD that the proposed revision of the SR 3.0.2 provisions section of TS 5.5.6 was unacceptable based on a position that applying the 25 percent extension to IST activities with frequencies greater than two years would be inappropriate. Therefore, the proposed revision to extend the applicability of SR 3.0.2 to frequencies in the IST is modified to limit the applicability to frequencies specified as two years or less.
The technical analysis in the original LAR, submitted by the Reference letter, discussed the need for the requested change to the ASME code referenced in TS 5.5.6, and noted that the requested changes had been incorporated into the Standard TS for BWR4 Plants, and that the technical analysis section of Technical Specification Task Force (TSTF) traveler TSTF479-A is applicable to CNS. That analysis has been amended to address the modified TS 5.5.6 revision proposed in this submittal.

NLS2006044 Page 2 of 2 The no significant hazards consideration evaluation included with the original LAR concluded that the proposed amendment presents no significant hazards consideration. The description of the proposed changes in the no significant hazards consideration evaluation is impacted by the modified TS revisions, and has been modified. However, the conclusion and the basis remain valid for the modified TS revisions submitted by this letter.
Attachment I provides revisions to Section 1.0, Description, and Section 2.0, Proposed Changes, and complete revised Section 4.0, Technical Analysis, and Section 5. 1, No Significant Hazards Consideration. Attachment 2 provides the revised page in markup format. Attachment 3 provides the revised page in final typed format.

NLS2006044 Attachment I Page 1 of4 Attachment 1 Revisions to Attachment 1 of Nebraska Public Power District License Amendment Request dated March 7,2006 Cooper Nuclear Station, Docket No. 50-298, DPR-46
Reference:
Letter from Randall K. Edington, Nebraska Public Power District, to U.S. Nuclear Regulatory Commission, dated March 7, 2006, "License Amendment Request to Update the American Society of Mechanical Engineers Code Referenced in TS Section 5.5.6, Inservice Testing Program" The following are paragraphs from Sections 1.0 and 2.0, and complete Sections 4.0 and 5.0 from the Reference letter, revised to reflect the revised technical specification. Added text is shown in bold font, with bars in the right-hand margin showing the location of the added text.
1.0 Description In addition, the scope of Frequencies specified to be within the applicability of SR
[Surveillance Requirement] 3.0.2 is expanded by adding mention of other normal and accelerated Frequencies specified as two years or less in the 1ST [Inservice Testing]
Program. This will eliminate any confusion regarding the applicability of SR 3.0.2 to IST Program Frequencies.
2.0 Proposed Changes The following are the proposed revisions to TS Section 5.5.6, "Inservice Testing Program."
- 2. TS 5.5.6.b states that the provisions of SR 3.0.2 are applicable to the required Frequencies. The phrase "and to other normal and accelerated Frequencies specified as 2 years or less in the Inservice Testing Program" is added to TS 5.5.6.b.
4.0 Technical Analysis The current 10 CFR 50.55a reflects that the ASME [American Society of Mechanical Engineers] OM [Operation and Maintenance] Code has been incorporated by reference into 10 CFR 50.55a(b), with 10 CFR 50.55a(b)(3) referring to the 1995 Edition through the 2003 Addenda of the ASME OM Code. NPPD is revising the CNS IST Program for the fourth 120-month interval based on the requirements of the 2001 Edition, 2003 Addenda of the OM Code. The proposed changes to TS 5.5.6 are necessary for consistency with the revised IST Program.
NLS2006044 Attachment I Page 2 of 4 The changes to TS Section 5.5.6 proposed in this amendment request have been incorporated into the comparable Section 5.5.7, "Inservice Testing Program," of NUREG-1433, Standard Technical Specifications for BWR4 Plants, Revision 3.1.
TSTF-479-A presented a Technical Analysis supporting the revisions to the IST Program section of NUREG-1433. The information presented in the Technical Analysis section of the TSTF is applicable to CNS.
CNS TS 5.5.6.b addresses the applicability of Surveillance Requirement (SR) 3.0.2 to the Frequencies in the IST Program. Based on the changes reflected in TSTF479-A, Nebraska Public Power District (NPPD) proposed a revision to this section in the submittal dated March 7, 2006, to state that the provisions of SR 3.0.2 are applicable to the specified Frequencies "and other normal and accelerated Frequencies specified in the Inservice Testing Program." The 1ST Program has Frequencies in excess of two years, for example five years and ten years. Applying the 25% extension allowed by SR 3.0.2 to these Frequencies would result in extensions of 1.25 years and 2.50 years, respectively. The NRC staff expressed a concern with applying SR 3.0.2 to frequencies greater than two years. To address that concern NPPD is modifying the proposed revision to state that the provisions of SR 3.0.2 are applicable to the specified Frequencies "and to other normal and accelerated Frequencies specified as 2 years or less in the Inservice Testing Program." As a result the applicability of SR 3.0.2 is limited to Frequencies in the IST Program of two years or less.
Amendment numbers 228 and 204 to Susquehanna Steam Electric Station (SSES) Units I and 2, respectively, dated December 7, 2005, are considered suitable precedents for this requested license amendment. In these amendments, SSES TS 5.5.6, "Inservice Testing Program," was revised by replacing reference to Section XI of the ASME Boiler and Pressure Vessel Code with reference to ASME Operation and Maintenance Code. (SSES did not propose all of the change reflected in TSTF-479-A). These SSES amendments are considered suitable precedents because both SSES and CNS must comply with 10 CFR 50.55a, and the IST Program for both must be written to the requirements of the latest edition and addenda of the ASME OM Code referenced in 10 CFR 50.55a(b). This proposed TS change involves no structure, system, or component (SSC) at SSES that might be different from a SSC at CNS.
5.0 Regulatory Safety Analysis 5.1 No Significant Hazards Consideration 10 CFR 50.91 (a)( 1) requires that licensee requests for operating license amendments be accompanied by an evaluation of no significant hazard posed by
NLS2006044 Attachment I Page 3 of 4 issuance of the amendment. Nebraska Public Power District (NPPD) has evaluated this proposed amendment with respect to the criteria given in 10 CFR 50.92(c). The following is the evaluation required by 10 CFR 50.91 (a)(1).
NPPD is requesting an amendment of the operating license for the Cooper Nuclear Station (CNS). The requested amendment revises the ASME Code referenced in Technical Specification (TS) Section 5.5.6, "Inservice Testing Program," from Section XI of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, to the ASME Code for Operation and Maintenance of Nuclear Power Plants (OM Code). The requested amendment also proposes to revise a paragraph in TS Section 5.5.6 that discusses applicability of Surveillance Requirement SR 3.0.2, to state that other normal and accelerated Frequencies specified as two years or less in the Inservice Testing (1ST) Program are included in the SR 3.0.2 applicability.
TSTF-479-A, Rev. 0, contained an evaluation of no significant hazards consideration against the three criteria of 10 CFR 50.92(c). That evaluation is applicable to CNS. The following evaluation of the changes is based on the evaluation in the TSTF and supports a finding of "no significant hazards" for the proposed amendment.
- 1. Do the proposed changes involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No The proposed changes revise the CNS TS for the IST Program to be consistent with the requirements of 10 CFR 50.55a(f)(4) for pumps and valves which are classified as ASME Code Class 1, Class 2, and Class 3.
The proposed changes incorporate revisions to the ASME Code that result in a net improvement in the measures for testing pumps and valves.
The proposed changes do not impact any accident initiators, analyzed events, or assumed mitigation of accident or transient events. They do not involve addition or removal of any equipment, nor any design changes to the facility.
Based on the above, NPPD concludes that the proposed changes do not involve a significant increase in the probability or consequences of an accident previously evaluated.
NLS2006044 Attachment I Page 4 of 4
- 2. Do the proposed changes create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No The proposed changes revise the CNS TS for the IST Program to be consistent with the requirements of 10 CFR 50.55a(f)(4) for pumps and valves which are classified as ASME Code Class 1, Class 2, and Class 3.
The proposed changes incorporate revisions to the ASME Code that result in a net improvement in the measures for testing pumps and valves.
The proposed changes do not involve a modification to the physical configuration of the plant (i.e., no new equipment will be installed) or a change in the methods governing normal plant operation. The proposed changes will not introduce a new accident initiator, accident precursor, or malfunction mechanism. There is no change in the types or increases in the amounts of any effluent that may be released off-site, and there is no increase in individual or cumulative occupational exposure.
Based on the above, NPPD concludes that these proposed changes do not create the possibility of a new or different kind of accident from any previously evaluated.
- 3. Do the proposed changes involve a significant reduction in a margin of safety?
Response: No The proposed changes revise the CNS TS for the 1ST Program to be consistent with the requirements of 10 CFR 50.55a(f)(4) for pumps and valves which are classified as ASME Code Class 1, Class 2, and Class 3.
The proposed changes incorporate revisions to the ASME Code that result in a net improvement in the measures for testing pumps and valves.
The safety function of the affected pumps and valves will be maintained.
Based on the above, NPPD concludes that these proposed changes do not involve a significant reduction in a margin of safety.
Based on the responses to the above questions, NPPD concludes that the proposed amendment presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c) and, accordingly, a finding of "no significant hazards consideration" is justified.
