SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 164 TO RENEWED FACILITY OPERATING LICENSE NO. DPR-22 NORTHERN STATES POWER COMPANY - MINNESOTA MONTICELLO NUCLEAR GENERATING PLANT DOCKET NO. 50-263
1.0 INTRODUCTION
By letter dated May 29, 2009 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML091690575), Northern States Power Company of Minnesota (NSPM, the licensee) requested changes to the Technical Specifications (TSs) for Monticello Nuclear Generating Plant. The licensee proposed to revise the applicability for isolation of the Reactor Water Cleanup (RWCU) system on a Standby Liquid Control (SLC) system initiation (Function 5.d, in Table 3.3.6.1-1, "Primary Containment Isolation Instrumentation") to align with the modes stated in Specification 3.1.7.
2.0 BACKGROUND
On September 15, 2005, the licensee submitted an application for a full-scope alternative source term (AST) amendment (Accession No. ML052640366), which was approved by the Nuclear Regulatory Commission (NRC) staff on December 7,2006, by Amendment No. 148 (Accession No. ML062790015). With adoption of the full-scope AST, the SLC system became credited for control of suppression pool pH to mitigate the radiological consequences of the design-basis accident loss-of-coolant accident in which fuel is damaged.
The licensee submitted a supplement to the AST full-scope License Amendment Request, dated August 21,2006 (Accession No. ML062350046), translating the proposed AST changes from the custom Technical Specifications (CTS) format to the corresponding improved Technical Specifications (ITS) format. The applicability of the SLC system in Specification 3.1.7 was revised in this supplement to reflect the addition of Mode 3 to the previously existing modes of applicability for the SLC System, i.e., Modes 1 and 2, which had been carried over from the CTS to the ITS. However, the applicability for isolation of the (RWCU) system on a SLC system initiation (Function 5.d in Table 3.3.6.1-1) was not changed to include Mode 3.
3.0 TECHNICAL EVALUATION
The SLC System is designed to provide the capability of bringing the reactor, at any time in a fuel cycle, from full power and minimum control rod inventory (which is at the peak of the xenon transient) to a subcritical condition with the reactor in the most reactive xenon free state without taking credit for control rod movement. The SLC System satisfies the requirements of 10 CFR 50.62 on anticipated transient without scram.
-2 The Bases for Specification 3.1.7 and Table 3.3.6.1-1 for Function 5.d state that isolation of the RWCU system on SLC system initiation is necessary to prevent dilution and removal of the boron solution by the RWCU system. In addition, Section 5.4.8 "Reactor Water Cleanup System (BWR)," of the Standard Review Plan states that design should include:
"Provisions to automatically terminate flow to the RWCS following liquid poison injection into the reactor water."
This provision was included in the SLC system design. Later this provision was captured in the applicable TS requirements. Therefore, the proposed change merely serves to restate the system design requirements in the applicable portions of the TS.
The NRC staff agrees that the proposed change will continue to assure that the SLC system and RWCU system design requirements and assumptions of the AST analysis are met. Based on this, the NRC staff finds that the proposed change is acceptable.
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.
5.0 ENVIRONMENTAL CONSIDERATION
The amendment changes a requirement with respect to the use of a facility component located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration and there has been no public comment on such finding (74 FR 37248). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.
6.0 CONCLUSION
The NRC staff has concluded, on the basis of the considerations discussed above, that (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
