SUBJECT:

MONTICELLO NUCLEAR GENERATING PLANT - ISSUANCE OF CORRECTED PAGES FOR AMENDMENT NO. 135 RE: BOILING WATER REACTOR VESSEL AND INTERNALS PROJECT REACTOR PRESSURE VESSEL INTEGRATED SURVEILLANCE PROGRAM (TAC NO. MB6460)

Dear Mr. Forbes:

This letter corrects minor editorial errors in Amendment No. 135, dated April 22, 2003, to Facility Operating License No. DPR-22 for the Monticello Nuclear Generating Plant.

Specifically, Technical Specification (TS) pages 122 and 146 were shown with the page numbers crossed out and the number "135" on the wrong line. These TS pages should have had "135" on the "Amendment No." line to reflect this as the new amendment number for these pages. Also, BWRVIP-86-A was mistakenly shown as BWRVIP-86 on page 4 of the safety evaluation.

Please replace the pages that were issued with Amendment No. 135 with the enclosed corresponding corrected pages. I regret any inconvenience this may have caused you.

Sincerely,

/RA/

L. Mark Padovan, Project Manager, Section 1 Project Directorate III Division of Licensing Project Management Office of Nuclear Reactor Regulation Docket No. 50-263

uncertainty bounds. In addition, NMC provided the following commitment in its February 28, 2003, submittal regarding when it will perform an updated RPV fluence analysis for the MNGP RPV:

The NMC commits to performing fluence calculations using [a] methodology in accordance with the RG 1.190 within 12 months following the final approval by the NRC for use of the RAMA [Radiation Analysis Methodology Application]

Code.

The RAMA Code is a discrete-ordinates neutron transport calculational code being developed by the EPRI to evaluate BWR vessel and internals fluences. Based on the NRC staffs discussions with EPRI, the NRC staff expects EPRI to submit complete RAMA Code documentation by no later than December 2003 for NRC staff review and approval. Therefore, allowing adequate time for NRC staff review of the RAMA Code, the NRC staff found this commitment by NMC to be acceptable. This is because the current RPV fluence calculations for MGNPs RPV are expected to remain conservative with respect to the actual, accumulated RPV neutron fluence through the expected date of fluence recalculation consistent with the commitment above.

NMCs license amendment request is consistent with the NRC staffs understanding of the decision given in Commission Memorandum and Order CLI-96-13. Accordingly, NMC provided the following revised Section 4.2.3.2 of the MGNP USAR incorporating the BWRVIP ISP into the MGNP licensing basis:

Additional surveillance specimens will be removed from the Monticello RPV in accordance with the Boiling Water Reactor Vessel [and] Internals Project (BWRVIP) Integrated Surveillance Program (ISP). The removal schedule developed by the BWRVIP ISP is included in the BWRVIP-86-A document. The l technical basis for the ISP is discussed in BWRVIP-78 . . . .

The NRC staff concludes that the information provided in the revised MNGP USAR is adequate to document NMCs intent to appropriately implement the BWRVIP ISP as the method for MNGP complying with the requirements of Appendix H to 10 CFR Part 50. As part of the implementation and documentation of NMCs intent to utilize the BWRVIP ISP for this purpose, NMC shall modify the MNGP USAR as noted in Section 3.0 of this SE and as stated in its February 28, 2003, submittal.

Deleting TS SR 4.6.B.2 from the TSs is acceptable since the SR 4.6.B.2 does not meet the minimum requirements of 10 CFR 50.36(c)(3), Surveillance requirements, for inclusion in the TSs. The SR pertains to RPV material test specimens and the associated program for monitoring RPV embrittlement and for establishing pressure-temperature curve limitations.

In addition, the licensee made associated changes to the TS Bases. The NRC staff has no objection to the licensees changes to the TS Bases.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Minnesota State official was notified of the proposed issuance of the amendment. The State official had no comments.
