1.0 INTRODUCTION
By application dated May 8, 2007 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML071370312), as supplemented by letter dated March 27, 2008 (ADAMS Accession No. MLxxxxxxxxx1), Entergy Operations, Inc. (the licensee), requested changes to the Technical Specifications (TS) for Arkansas Nuclear One, Unit No. 2 (ANO-2).
The proposed changes would revise TS 3.1.1.4, Moderator Temperature Coefficient (MTC).
Specifically, the change will modify the surveillance frequency to be based on effective full power days (EFPD) instead of boron concentration.
The supplemental letter dated March 27, 2008, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the staff's original proposed no significant hazards consideration determination as published in the Federal Register on June 5, 2007 (72 FR 31099).
2.0 REGULATORY EVALUATION
In Section 50.36, Technical specifications, of Title 10 of the Code of Federal Regulations (10 CFR), the Commission established the requirement that each applicant for a license authorizing operation of a production or utilization facility shall include proposed TSs. Pursuant to 10 CFR 50.36(d), TSs are required to include items in the following five specific categories related to station operation: (1) safety limits, limiting safety system settings, and limiting control settings; (2) limiting conditions for operation; (3) surveillance requirements (SR); (4) design features; and (5) administrative controls. This amendment is within the safety limits, limiting safety system settings, and limiting control settings category (10 CFR 50.36(d)(1)).
The proposed changes have been evaluated against the following to determine whether applicable regulations and requirements continue to be met.
General Design Criterion 11 of Appendix A to 10 CFR Part 50, the reactor core and its interaction with the Reactor Coolant System (RCS) must be designed for inherently stable power 1
As of the date of issuance of this amendment, document has not yet been placed into ADAMS.
operation, even in the possible event of an accident. In particular, the net reactivity feedback in the system must compensate for any unintended reactivity increases.
3.0 TECHNICAL EVALUATION
The MTC relates a change in core reactivity to a change in reactor coolant temperature. A positive MTC means that reactivity increases with increasing moderator temperature; conversely, a negative MTC means that reactivity decreases with increasing moderator temperature. The reactor is designed to operate with a negative MTC over the largest possible range of fuel cycle operation. Therefore, a coolant temperature increase will cause a reactivity decrease, so that the coolant temperature tends to return toward its initial value. Reactivity decrease that causes a coolant temperature increase will thus be self limiting and stable power operation will result.
The RCS boron concentrations associated with the current SRs were included in the original ANO-2 TS. The fuel cycle length was 12 months at that time with a beginning of cycle (BOC)
RCS boron concentration of approximately 1000 ppm (parts per million). The 800 ppm RCS boron concentration corresponded to a BOC measurement of the MTC. The 300 ppm RCS boron concentration corresponded to reaching approximately two-thirds of the expected core burnup. When the cycle length was changed to 18 months, the 800 ppm RCS boron concentration still provided an MTC measurement early in the cycle and the 300 ppm RCS boron concentration still provided a middle of cycle measurement. The proposed change will continue to require MTC measurement at approximately the same intervals.
MTC values are predicted at selected times during the safety evaluation analysis and are confirmed to be acceptable by measurement. The intent of the SRs is to assure the MTC response is as predicted. The SRs for measurement of the MTC are required prior to entering Mode 1 and at the beginning and middle of each fuel cycle for confirmation of the limiting MTC values. The SR 4.1.1.4.2(a) prior to Mode 1 is unchanged. The proposed change will associate the interval for the SRs 4.1.1.4.2(b) and (c) with EFPD rather than RCS boron concentration.
The interval of the surveillances will not change but the timing of SRs 4.1.1.4.2(b) and (c) may change slightly. The MTC changes smoothly from the most positive (least negative) to the most negative value during fuel cycle operation, as the RCS boron concentration is reduced to compensate for fuel depletion. The requirement for measurement prior to operation greater than 5 percent rated thermal power (RTP) satisfies the confirmatory check on the most positive (least negative) MTC value.
The licensee originally proposed TS Action 4.1.1.4.2.b to be performed "prior to reaching" 40 EFPD to be consistent with the Waterford Steam Electric Station, Unit 3 TSs. However, the Standard Technical Specification (STS) wording is "within 7 EFPD" of reaching 40 EFPD.
Following a teleconference discussion of this difference with the licensee, the licensee agreed that adoption of the STS wording was acceptable. Therefore, by letter dated March 27, 2008, the licensee proposed to change TS 4.1.1.4.2.b to use the STS wording of "within 7 EFPD of reaching 40 EFPD." This is an administrative change from the originally proposed TS and has no impact on the intent of MTC testing requirements.
The revised SRs 4.1.1.4.2(b) and (c) provide for measurements of MTC, within 7 EFPD of reaching 40 EFPD and two-thirds of expected core burnup. This provides the confirmatory check of the most negative MTC value. The licensee proposes to perform these measurements
at any thermal power level greater than 5 percent, so that the projected end of cycle (EOC) MTC may be evaluated before the reactor actually reaches the EOC condition. MTC values may be extrapolated and compensated to permit direct comparison to the specified MTC limits. The STS are worded to allow a plant to perform these tests at any power; however, the licensee stated that it is not prudent to perform these tests or induce plant transients at low-power levels because such testing could result in entering/exiting Modes 1 and 2 inadvertently. Mode 2 governs plant operation at less than or equal to 5 percent power with the reactor critical. Mode 1 governs plant operation at all power levels above 5 percent. Oftentimes, there are different TS requirements depending on which mode of operation a plant is in; therefore, the 40 EFPD and two-thirds core-life MTC tests are modified to be performed at greater than 5 percent RTP to avoid unnecessary mode changes and/or performing the tests during relatively unstable, lower power levels of operation. The licensee has proposed that the current TS 5 percent limitation be maintained in the proposed SR revisions, which is more restrictive than the STS.
The TS change continues to provide assurance that the MTC is measured at specific intervals in the fuel cycle regardless of the fuel design (i.e., at the beginning and middle of the fuel cycle).
The measurement is performed at any RTP level greater than 5 percent which is consistent with the current TS applicability statement. In addition, the proposed surveillances are consistent with NUREG-1432. The proposed change assures the original intent of the current SRs. With the addition of Integral Fuel Burnable Absorbers (i.e., zirconium diboride) fuel design, peak RCS boron concentration occurs later in the fuel cycle. As such, the proposed change is necessary to ensure the MTC measurement is performed at the appropriate intervals. The nuclear design of the core ensures that the combined response of all reactivity coefficients in the power operating range to an increase in reactor thermal power yields a net decrease in reactivity. Therefore, the intent of the current TSs are met and the NRC staff concludes that the proposed TS changes are acceptable.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Arkansas 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 installation or 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 published in the Federal Register on June 5, 2007 (72 FR 31099). 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 Commission has concluded, based on 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 amendment will not be inimical to the common defense and security or to the health and safety of the public.
