SUSQUEHANNA STEAM ELECTRIC STATION, UNITS 1 AND 2 DOCKET NOS. 50-387 AND 388

1.0 INTRODUCTION

By application dated March 4, 2004 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML040710865), PPL Susquehanna, LLC (PPL, the licensee),

requested changes to the Technical Specifications (TSs) for Susquehanna Steam Electric Station, Units 1 and 2 (SSES 1 and 2).

The proposed changes would revise the SSES 1 and 2 TSs by changing Table 3.3.5.1-1 to clarify that four low-pressure coolant injection (LPCI) pump discharge pressure-high channels are required for each automatic depressurization system (ADS) trip function.

2.0 REGULATORY EVALUATION

The Nuclear Regulatory Commission (NRC) finds that PPL, in its March 4, 2004, submittal, identified the applicable regulatory requirements. The regulatory requirements and guidance which the NRC staff considered in its review of the application are as follows:

1. Title 10 of the Code of Federal Regulations (10 CFR) establishes the fundamental regulatory requirements with respect to the reactivity control systems. Specifically, General Design Criterion (GDC) 13, Instrumentation and control, states, in part, that instrumentation shall be provided to monitor variables and systems over their anticipated ranges for normal operation, for anticipated operational occurrences, and for accident conditions as appropriate to assure adequate safety.
2. Section 50.36, Technical specifications, provides the regulatory requirements for the content required in a licensees TSs. Section 50.36 states, in part, that the TSs will include surveillance requirements to assure that the quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation (LCO) will be met.

3.0 TECHNICAL EVALUATION

3.1 Background The ADS control system is designed to reduce reactor vessel pressure during a loss-of-coolant accident in which the high-pressure coolant injection system is not available so that the core spray (CS) system or LPCI system can inject water into the reactor vessel. ADS monitors the discharge pressures of the four LPCI pumps and the four CS pumps. Each ADS trip system receives a discharge pressure permissive either from: (a) both CS pumps in the division or (b) from either of the two LPCI pumps in the associated division. The signals are used as a permissive for ADS actuation, indicating that there is a source of core coolant available once the ADS has depressurized the vessel. With operation of both CS pumps or one of the two LPCI pumps in a division, sufficient flow is available to permit automatic depressurization.

The SSES 1 and 2 bases for TS 3.3.5.1 describe that the ADS pressure permissive logic for CS has one pressure channel for each pump. Since it takes both CS pumps associated with that ADS Division (2-of-2 logic) to provide the permissive, the "Required Number of Channels Per Function" is specified as "2." Each LPCI pump has two pressure channels arranged in a 2-of-2 logic (for each pump) to provide the ADS permissive. As such, the current requirements stating "2" required channels is interpreted as "2 per pump." With two pumps supporting each division, as described in the bases, this presentation requires all "4" channels to be operable. These bases and the supporting intent are based on the amendment request associated with conversion to the Improved Standard TSs, Amendment Nos. 178 (Unit 1) and 151 (Unit 2)

(Reference 1).

On January 31, 1985, PPL requested an Amendment (Reference 2) that was the basis for approval of TS Amendments Nos. 44 for Unit 1 and 11 for Unit 2 (Reference 3). These amendments provided the requirement for the minimum required channels per trip system in Table 3.3.3-1 for the ADS-LPCI pressure permissive as "2", and included a footnote allowance to have either residual heat removal (RHR) pump satisfy the requirement. Amendments Nos.

44 and 11 also approved requirements which allowed for two CS pump discharge pressure channels to satisfy the required ADS logic channels. As such, Amendments Nos. 44 and 11 requirements stating "2" required channels were interpreted for CS as "2 per loop" (one for each pump in that loop supporting one Division of ADS). For RHR, the interpretation was "2 per pump" with two pumps supporting each Division. Footnotes provided with this amendment allowed for only 1-CS or 1-RHR pump to meet the minimum requirements.

Amendments Nos. 178 for Unit 1 and 151 for Unit 2 (Reference 1) approved a more restrictive operability requirement by requiring all channels to be operable. In the Improved TS (ITS)

Table 3.3.5.1-1, the required number of ADS-LPCI pressure permissive channels continued to reflect "2" for each trip system. However, the bases and documentation associated with the ITS conversion clearly relates the intent to require both the channels for both LPCI pumps for each ADS trip system, which is all four channels in each trip system.

3.2 Proposed Change The proposed editorial change revises SSES 1 and 2 TSs, Section 3.3.5.1, "Emergency Core Cooling System (ECCS) Instrumentation," specifically Table 3.3.5.1-1, Functions 4.f and 5.f, "Low Pressure Coolant Injection Pump Discharge Pressure - High," for ADS trip systems A and

B. The "Required Channels Per Function" is revised from "2" to "4." For each ADS trip system the LPCI function is applied to each LPCI pump. Therefore, to satisfy the operability requirements, each LPCI pump must have the "2" discharge pressure permissive channels associated with that trip system operable. As such, the requirement stating "2" required channels is interpreted as "2 per pump" with two pumps supporting each trip system, for a total of four channels required for each trip system.

3.3 Conclusion Based on the results of the review, the NRC staff finds the proposed editorial changes to TS Table 3.3.5.1-1 acceptable. The proposed changes will more clearly present the requirement that is consistent with the typical definition of channel (e.g., each discharge pressure sensor is part of a unique "channel"), minimizing the potential for misinterpretation and operator error in implementation of the requirements. The TS Actions for inoperable channels apply consistently to any number of inoperable channels and are not impacted by this change. Since there is no change in the actual channels required operable, this is an editorial change only.

4.0 STATE CONSULTATION

In accordance with the Commissions regulations, the Pennsylvania State Official was notified of the proposed issuance of the amendments. 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 (69 FR 22881). 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.
