DPR-25 EXELON GENERATION COMPANY, LLC DRESDEN NUCLEAR POWER STATION, UNITS 2 AND 3 DOCKET NOS. 50-237 AND 50-249
1.0 INTRODUCTION
By application to the U. S. Nuclear Regulatory Commission (Commission, Staff, NRC), dated August 16, 2002, Exelon Generation Company, LLC, (the licensee) requested changes to the Technical Specifications (TSs) for the Dresden Nuclear Power Station, Units 2 and 3.
The proposed changes would revise the specified function description, surveillance requirements (SRs) and allowable value (AV) that apply to Unit 3 in TS Table 3.3.1.1-1, Reactor Protection System Instrumentation, Function 7, Scram Discharge Volume Water Level-High. These proposed changes support the licensees plan to upgrade to the Unit 3 scram discharge volume (SDV) water level-high instrumentation with more reliable instrumentation. In addition, the proposed changes add an SR to the existing Unit 2 and 3 SDV water level differential pressure switches specified in Function 7.b of TS Table 3.3.1.1-1.
Specifically, the licensee has proposed changes that would revise TS Table 3.3.1.1-1, Function 7, as follows:
- a. Function 7.a, change the term Float Switch to Level Indicating Switch.
- b. Function 7.a, add SRs 3.3.1.1.1 and 3.3.1.1.12 to each SR listing (i.e., listing for Modes 1, 2, and the specified condition in Mode 5) followed by new table footnote designator d.
- c. Add a new footnote (d), Specified SR performance only required for Unit 3.
- d. Function 7.b, add SR 3.3.1.1.12 to each SR listing (i.e., listing for Modes 1, 2, and the specified condition in Mode 5).
- e. Functions 7.a and 7.b, revise the AV for Unit 3 from # 39.1" to #38.7" gallons in four locations.
2.0 REGULATORY EVALUATION
The current instrumentation for the SDV high-level trip, Function 7.a of TS Table 3.3.1.1-1, Reactor Protection System Instrumentation, utilizes locally mounted, non-indicating Magnetrol level float switches for Unit 3 and non-indicating thermal probes for Unit 2 which initiate a reactor scram when the monitored parameter exceeds its specified limit. If the SDV were filled to a point where there was insufficient volume to accept the water from the control drives that are displaced during scram, control rod insertion would be hindered. This scram is required to be functional in Modes 1, 2, and 5 with any control rod withdrawn from a reactor core cell containing one or more fuel assemblies. The licensee has applied all requirements for the existing instruments to the new instruments and has proposed SRs based on the new instruments.
The staff finds that the licensee in Section F of Attachment A of its submittal identified the applicable regulatory requirements. The regulatory requirements on which the staff based its acceptance are in Section 50.55a(h)(2) of Title 10 of the Code of Federal Regulations (10 CFR), which encompasses the detailed requirements discussed by the licensee in its submittal.
3.0 TECHNICAL EVALUATION
The staff has reviewed the licensees regulatory and technical analyses in support of its proposed license amendment which are described in Sections A through F of the licensees submittal. Based on the review of the licensees submittal, the staff concludes that the proposed TS changes are acceptable. The detailed evaluation below will support the conclusion 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.
3.1 Proposed Change: TS Table 3.3.1.1-1 Function 7.a - Change the term Float Switch to Level Indicating Switch.
Evaluation: This change is necessary to reflect the new SDV level-monitoring instrumentation and is administrative in nature; therefore, the staff finds it acceptable.
3.2 Proposed Change: TS Table 3.3.1.1-1 Function 7.a - Add SR 3.3.1.1.1 and SR 3.3.1.1.12 to each SR listing (i.e., listing for Mode 1, 2, and 5) followed by new table footnote designator d.
Evaluation: The licensee has added SR 3.3.1.1.1, channel check, and SR 3.3.1.1.12, trip unit calibration requirements, for the Unit 3 SDV water level instrumentation. Neither the existing instruments (thermal switches for Unit 2 and the float switches for Unit 3) nor the differential pressure instrumentation channel used for Function 7.b provide SDV water level indication. However, the new Unit 3 instruments provide indication and, therefore, allow for performance of the channel check. The thermal switches used in Unit 2 do not contain analog trip units and, therefore, do not require calibration.
The licensee has added calibration requirements for the trip units at the frequency of 92 days both for the Unit 3 replacement instrumentation and for the existing differential pressure instrumentation used for Function 7.b, which also has analog trip units. The licensee has based the 92-day calibration frequency on the General Electric Company and the Boiling Water Reactor Owners Group topical reports which were previously approved by NRC (NRC letter to O. D. Kingsley, Dresden Issuance of Amendments Changing Allowable Out-of-Service Times and Surveillance Test Intervals, dated August 2, 2000). The licensee has further stated that the 24-month channel calibration for the new instruments continues to be allowed provided that the analog trip units are calibrated every 92 days. The licensee has used drift values in accordance with the setpoint methodology described in Nuclear Standard NES-EIC-20.4, Analysis of Instrument Channel Setpoint Error and Instrument Loop Accuracy, which was approved by NRC in Dresden Amendments 185/180 dated March 30, 2001. Since the addition of SR 3.3.1.1.1 and SR 3.3.1.1.12 make the TSs more comprehensive and is consistent with a previously approved NRC methodology, the proposed change is acceptable.
3.3 Proposed Change: TS Table 3.3.1.1-1 Function 7.a - Add new footnote (d),
Specified SR performance only required for Unit 3.
Evaluation: Since the footnote clarifies that the particular SR is only required for Unit 3 equipment as discussed in item b above, this change is administrative in nature and, therefore, is acceptable to the staff.
3.4 Proposed Change: TS Table 3.3.1.1-1 Function 7.b - Add SR 3.3.1.1.12 to each SR listing (i.e., listing for Modes 1, 2, and the specified condition in Mode 5).
Evaluation: The addition of trip unit calibration provides appropriate SRs for the existing instrumentation for this function as discussed in item c earlier. Although SR 3.3.1.1.12 is not currently specified for this function, Dresden calibrates the trip units every 92 days. Since the addition of SR 3.3.1.1.12 for this function makes the TSs more comprehensive, the staff finds the proposed change acceptable.
3.5 Proposed Change: TS Table 3.3.1.1-1, Functions 7.a and 7.b - Revise the AV for Unit 3 from #39.1" to #38.7" gallons in the four printed locations.
Evaluation: The licensee had used the previously NRC-approved setpoint methodology to determine the AV for these instruments. There is no change to the analytical limit for these functions. On this basis, the staff finds the new AV acceptable.
4.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Illinois State official was notified of the proposed issuance of the amendment. The State official had no comments.
5.0 ENVIRONMENTAL CONSIDERATION
The amendments change 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 amendments involve 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 amendments involve no significant hazards consideration, and there has been no public comment on such finding (67 FR 68737). Accordingly, the amendments meet 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 amendments.
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 Commissions 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.
