ATTACHMENT 1 LAR H08-06 RAI LR-N09-0122 REQUEST FOR ADDITIONAL INFORMATION REGARDING PROPOSED LICENSE AMENDMENT MODE CHANGE LIMITATIONS HOPE CREEK GENERATING STATION DOCKET NO. 50-354 By application dated January 5, 2009 (Agencywide Documents Access and Management System (ADAMS) Accession 'No. ML090130384), PSEG Nuclear LLC (PSEG or the licensee) submitted a license amendment request for the Hope Creek Generating Station (HCGS). The proposed amendment would modify Technical Specifications (TS) requirements for mode change limitations in accordance with Revision 9 of Nuclear Regulatory Commission (NRC)-approved TS Task Force (TSTF) change TSTF-359, "Increase Flexibility in-Mode Restraints."

In a Federal Register notice dated April 4,.2003 (68 FR 16579), the NRC staff issued a.

notice of availability of a model application for proposed license amendments adopting TSTF-359 using the consolidated line item improvement process (CLIIP). The notice also included a model safety evaluation (SE). In its application dated January 5, 2009, the licensee affirmed the applicability of the model SE.

The NRC staff has reviewed the information the licensee provided that supports the proposed amendment and would like to discuss the following issues to clarify the submittal.

QUESTION I

1)

Licensees interested in increasing flexibility in mode restraints by implementing Revision 9 of TSTF-359 must, as applicable, delete pre-existing limiting condition for operation (LCO) 3.0.4 exceptions in the current TSs. Deletion.of pre-existing LCO 3.0.4 exceptions that contain plant-specific non-standard LCO 3.0.4 exceptions may result in TS requirements that are different from those justified by the CLIIP model SE (i.e., CLIIP SE is based onTSTF-359 changes to the Standard Technical Specifications (STS)).

HCGS LCO 3.6.3 provides the operability requirements for primary containment isolation valves (PCIVs). ACTION a.4 in LCO 3.6.3, which contains a plant-specific non-standard LCO 3.0.4 exception, would be deleted by the proposed amendment. ACTION a.4 states:

The provisions of Specification 3.0.4 are not applicable provided that within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> the affected penetration is isolated in accordance with ACTION a.2, or a.3, above, and provided that-the associated system, if applicable, is declared inoperable and the appropriate ACTION statements for that -system are performed.

  • ;Pro-vide.-further justification for-the;:propose.d-deletion.ofLACTION :a4 in LCO 3.6-63:-,*Specifically-demonstrate that the proposed iamendment:

QUESTION 2

2).Section

.- 1.1, "Temporary -Risk lncreases4"of the model 'SE for theECLIIP,states, in part, that:

A major element that limits,;the risk of the-proposed mode'change flexibility isýthe exclusion, cif"erainssystemsýand ;associated LCOs for-the mode'change. allowance. T*e'chnicahspecifications~allow

ATTACHMENT 1 LAR H08-06 RAI LR-N09-0122 The SE identified -the following systems and -components, applicable.to BWR/4 plants, as higher-risk systems and components, when the plant is entering a new

-mode (excluding entering Mode 4).

High Pressure Coolant Injection System Reactor Core Isolation Cooling System Diesel Generators (including other Emergency/Shutdown AC Power Supplies)

Hardened Wetwell Vent System Provide a plant-specific evaluation of the risk-importance of the Hardened Wetwell Vent System and the Emergency/Shutdown AC Power Supplies to show that they are not higher risk systems which should be excluded from the scope of LCO 3.0.4(b) to meet the SE-findings contained in Section 3.1.3, "Risk Assessment and Risk Management of Mode Changes."

RESPONSE TO QUESTION 2 The EDGs in Modes 1, 2 and 3 are excluded from the scope of LCO 3.0.4.b in accordance with TSTF-359 as documented in LAR H08-06 (there are no other Emergency/Shutdown AC Power Supplies).

TS Actions do not apply to the Hardened Torus (Wetwell) Vent; this is acknowledged in the NRC response to Comment #9 in the Notice of Availability of the CLIIP (Federal Register Notice 68 FR 16579). The requirements of 10 CFR 50.65(a)(4) and guidance of NUMARC 93-01 would provide the appropriate considerations for determining the acceptability of, and risk management actions necessary to support the use of LCO 3.0.4.b with the Hardened Torus Vent System out of service.

QUESTION 3

3)

Please address the following comment provided by the New Jersey (NJ) Bureau of Nuclear Engineering (BNE):

The proposed changes to the Bases pages (Attachment 4) state on the third page that 'The LCO 3.0.4.b risk assessments do not have to be documented." The position of the NJ BNE is that documentation of these risk assessments is necessary in order to provide a method for verifying that these risk assessments address all risk concerns, are performed and reviewed correctly, are approved by the proper level of management, and will become a permanent record. Without documentation, any future inquiries as to a specific operational condition change that required a risk

-assessment would be severely hampered. Therefore, we suggest that.the above quoted sentence be deleted from the proposed Bases pages.

ATTACHMENT 1 LAR H08-06 RAI LR-N09-0122 RESPONSE'TO QUESTION 43'.

The TSTF-359 proposed Bases correctly state that there is no regulatory requirement for

.documentation of each individual use of the risk assessment and risk management actions-for use of LCO 3.0.4.b.

A licensee adopting this CLIIP change is required to commit in the Bases to the Technical Specifications to follow Regulatory Guide 1.182. Regulatory Guide 1.182, "Assessing and Managing Risk Before Maintenance Activities at Nuclear Power Plants,"

endorses NUMARC 93-01 Section 11. NUMARC 93-01, Section 11 requires that the risk assessment process -be proceduralized. Section 11.3.9 states that the normal work control process suffices as a record that the assessment was performed and that it is not necessary to document the basis of each assessment. Normal PSEG practice is to document 3.0.4.b risk assessments, but adoption of the CLIIP does not create a new regulatory requirement for documentation of risk assessments.performed to comply with the requirements of 10 CFR 50.65(a)(4).

However, PSEG will remove the quoted sentence from the HCGS Bases (under the TS

QUESTION 4

4)

Section 3.1.1, "Temporary Risk Increases," of themodel SE for the CLIIP states, in part, that:

If a licensee identifies a higher-risk system for only some of the

-modes of applicability, the TS for that system would be-modified by a note that reads, for example, "LCO 3.0.4(b) is not:applicable when entering MODE 1 from MODE 2." Systems identified as higher riskfor Modes 4 and 5 for BWRs, are also excluded from transitioning up to-the mode of higher risk.... In addition, mode

-transitions for Modes 4 :and 5-for BWRs, will be addressed.by administrative controls.

The SE identified the Residual Heat Removal System-for BWR/4 plants, :as a

.higher-risk systems, when-the plant is entering Mode 4. Address-the use of administrative controls when entering Mode 4 for this system.

RESPONSE TO QUESTION 4 Entry into Mode 4 from Mode 5 is controlled by the Shutdown Safety Management Program (SSMP). The SSMP (PSEG Procedure OU-AA-1 03) is designed to meet the applicable requirements of 10CFR50.65(a)(4) and NUMARC 93-01, " Industry Guidance for monitoring the -Effectiveness of Maintenance at Nuclear:Power'Plants ". 'This is consistent with the TSTF analysisthat expansion of the -applicability of LCO 3.04 and SR 3.0.4 to the refueling and :shutdownMODES and -other specified conditions is

.considered acceptable, without explicit analysis jand identification of higher risk systems,

ATTACHMENT 1 LR-N09-0122 LAR H08-06 RAI because the risk in these MODES and other specified conditions -are adequately assessed and -managed by 10CFR50.65 (a)(4) and NUMARC 93-01.
