Enclosure I PG&E Letter DCL-03-118 EVALUATION

1.0 DESCRIPTION

The proposed amendment would modify Technical Specification (TS) requirements for mode change limitations in Limiting Condition for Operation (LCO) 3.0.4 and Surveillance Requirement (SR) 3.0.4.

The changes are consistent with Nuclear Regulatory Commission (NRC) approved Industry/Technical Specification Task Force (TSTF) Standard TS (STS) change TSTF-359 Revision 8, as modified by the notice in the Federal Register published on April 4, 2003. That Federal Register Notice (FRN) announced the availability of this TS improvement through the Consolidated Line Item Improvement Process (CLIIP). TSTF-359, Revision 8, was subsequently revised to incorporate the modifications discussed in the April 4, 2003, FRN and other minor changes, and was submitted to the NRC on April 28, 2003, as TSTF-359, Revision 9.

2.0 ASSESSMENT

2.1 Applicability of Published Safety Evaluation Pacific Gas and Electric Company (PG&E) has reviewed the safety evaluation dated April 4, 2003, as part of the CLIIP. This review included a review of the NRC staffs evaluation, as well as the information provided to support TSTF-359 Revision 8, and included the updates made in TSTF-359, Revision 9. PG&E has concluded that the justifications presented in the TSTF proposal and the safety evaluation prepared by the NRC staff are applicable to Diablo Canyon Power Plant (DCPP) Units I and 2, and justify the incorporation of the changes in the DCPP TS.

2.2 Optional Changes and Variations PG&E is not proposing any variations or deviations from the TS changes described in TSTF-359 Revision 9 and the NRC staffs model safety evaluation dated April 4, 2003.

Due to differences between DCPP TS and TS Bases and the model STS in NUREG-1431, Revision 2, "Standard Technical Specifications, Westinghouse Plants," in several cases variances from the TSTF mark-up changes are made.

These variances are discussed below and do not affect the adoption or application of TSTF-359, Revision 9.

In TS 3.1.1, "Shutdown Margin (SDM)," the Applicability Note stating, 'While this LCO is not met, entry into MODE 5 from MODE 6 is not permitted," is I

Enclosure I PG&E Letter DCL-03-118 deleted. Prior to approval of TSTF-359, LCO 3.0.4 and SR 3.0.4 contained a Reviewer's Note which required a plant-specific evaluation and, if necessary, application of specific restrictions on mode changes or Required Actions in individual LCOs. This plant-specific restriction added as a result of the evaluation described in the Reviewer's Note to LCO 3.0.4 is therefore deleted.

In TS 3.3.1, "Reactor Trip System (RTS) Instrumentation," the Note in Condition C stating, "While this LCO is not met for Function 19, 20 or 21 in MODE 5, making the Rod Control System capable of rod withdrawal is not permitted," is deleted. Prior to approval of TSTF-359, LCO 3.0.4 and SR 3.0.4 contained a Reviewer's Note which required a plant-specific evaluation and, if necessary, application of specific restrictions on mode changes or Required Actions in individual LCOs. This plant-specific restriction added as a result of the evaluation described in the Reviewer's Note to LCO 3.0.4 is therefore deleted.

In TS 3.4.8, 'RCS Loops - MODE 5, Loops Not Filled," the Applicability Note stating, "While the LCO is not met, entry into MODE 5, Loops Not Filled, from MODE 5, Loops Filled, is not permitted," is deleted. Prior to approval of TSTF-359, LCO 3.0.4 and SR 3.0.4 contained a Reviewer's Note which required a plant-specific evaluation and, if necessary, application of specific restrictions on mode changes or Required Actions in individual LCOs. This plant-specific restriction added as a result of the evaluation described in the Reviewer's Note to LCO 3.0.4 is therefore deleted.

In the TSTF mark-ups, STS 3.5.3, "ECCS - Shutdown," an ACTIONS Note is added to indicate that the new LCO 3.0.4b provisions are not applicable to the emergency core cooling system (ECCS) high head subsystem. In the DCPP TS, an ACTIONS Note is added using DCPP-specific terminology of ECCS Centrifugal Charging Pump subsystem.

In the TSTF mark-ups, STS 3.6.9, "Hydrogen Mixing System (HMS)," is modified. DCPP TS do not include this TS, so no changes are needed.

In TS 3.9.1, 'Boron Concentration," the Applicability Note stating, "While this LCO is not met, entry into MODE 6 from MODE 5 is not permitted," is deleted.

Prior to approval of TSTF-359, LCO 3.0.4 and SR 3.0.4 contained a Reviewer's Note which required a plant-specific evaluation and, if necessary, application of specific restrictions on mode changes or Required Actions in individual LCOs. This plant-specific restriction added as a result of the evaluation described in the Reviewer's Note to LCO 3.0.4 is therefore deleted.

2 PG&E Letter DCL-03-118 In TS 3.9.6, 'Residual Heat Removal (RHR) and Coolant Circulation - Low Water Level," the Applicability Note stating, 'While this LCO is not met, entry into a MODE or other specified condition in the Applicability is not permitted,"

is deleted. Prior to approval of TSTF-359, LCO 3.0.4 and-SR 3.0.4 contained a Reviewers Note which required a plant-specific evaluation and, if necessary, application of specific restrictions on mode changes or Required Actions in individual LCOs. This plant-specific restriction added as a result of the evaluation described in the Reviewers Note to LCO 3.0.4 is therefore deleted.

3.0 REGULATORY ANALYSIS

3.1 No Significant Hazards Consideration Determination PG&E has reviewed the proposed no significant hazards consideration determination published in the Federal Register as part of the Consolidated Line-Item Improvement Process. Pacific Gas and Electric Company has concluded that the proposed no significant hazards consideration determination presented in the Federal Register Notice is applicable to Diablo Canyon Power Plant and is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91 (a).

3.2 Verification and Commitments As discussed in the notice of availability published in the Federal Register on April 4, 2003, for this TS improvement, plant-specific verifications were performed as follows:

PG&E has established TS Bases for LCO 3.0.4 and SR 3.0.4, which state that use of the TS mode change limitation flexibility established by LCO 3.0.4 and SR 3.0.4 is not to be interpreted as endorsing the failure to exercise the good practice of restoring systems or components to operable status before entering an associated mode or other specified condition in the TS Applicability.

The modification also includes changes to the bases for LCO 3.0.4 and SR 3.0.4 that provide details on how to implement the new requirements. The bases changes provide guidance for changing modes or other specified conditions in the Applicability when an LCO is not met. The bases changes describe in detail how: LCO 3.0.4.a allows entry into a mode or other specified condition in the Applicability with the LCO not met when the associated actions to be entered permit continued operation in the mode or other specified condition in the Applicability for an unlimited period of time; LCO 3.0.4.b allows entry into a mode or other specified condition in the Applicability with the LCO not met after performance of a risk assessment addressing inoperable systems and components, consideration of the results, determination of the acceptability of 3

PG&E Letter DCL-03-118 entering the MODE or other specified condition in the Applicability, and establishment of risk management actions, if appropriate; and LCO 3.0.4.c allows entry into a MODE or other specified condition in the Applicability with the LCO not met based on a note in the specification, which is typically applied to specifications which describe values and parameters (e.g., Containment Air Temperature, Containment Pressure, MCPR, Moderator Temperature Coefficient), though it may be applied to other specifications based on NRC plant-specific approval. The bases also state that any risk impact should be managed through the program in place to implement 10 CFR 50.65(a)(4) and its implementation guidance, NRC Regulatory Guide 1.182, "Assessing and Managing Risks Before Maintenance Activities at Nuclear Power Plants," and that the results of the risk assessment shall be considered in determining the acceptability of entering the mode or other specified condition in the Applicability, and any corresponding risk management actions. In addition, the bases state that upon entry into a mode or other specified condition in the Applicability with the LCO not met, LCO 3.0.1 and LCO 3.0.2 require entry into the applicable Conditions and Required Actions for no more than the duration of the applicable Completion Time or until the LCO is met or the unit is not within the Applicability of the TS. The bases also state that SR 3.0.4 does not restrict changing modes or other specified conditions of the Applicability when a surveillance has not been performed within the specified frequency, provided the requirement to declare the LCO not met has been delayed in accordance with SR 3.0.3.

The TS Bases will be revised to reflect the changes to the affected TS and will be implemented in accordance with TS 5.5.14, "Technical Specification (TS) Bases Control Program," as part of the implementation of this amendment, upon NRC approval of this amendment application.

4.0 Environmental Evaluation PG&E has reviewed the environmental evaluation included in the model safety evaluation dated April 4, 2003, as part of the C[IIP. PG&E has concluded that the staffs findings presented in that evaluation are applicable to DCPP and the evaluation is hereby incorporated by reference for this application.
