Dear Dr. Murley:
In 1990, Quad Cities Station initiated a formal program to enhance the Station's performance in various aspects of plant eration. The Performance Enhancement Program
- (PEP) was developed by assessing exist improvement plans, Identifying potential
- weaknesses and prioritizing irr.piovement tions. Nocessary improvements to the Technical Specifications were identified as one of tho Station's top priority issues. Details of the goal and methodology for the Technical Specification Upgrade Program are provided in the Executive Summary section of the proposed amendment. The program has been previously discussed with members of the NRR staff, j
i Pursuant to 10 CFR 50.90, Commonwealth Edison Company (CECO) proposes to 1
- amend Appendix A, Technical Specifications to Facility Operating Licenses DPR 29 and DPR 30. The osed amendment deletes existing Technical Speelfication Section 3.11/4.11,
- High Energy Integrity (Outside Containment)". Section 3.11/4.11 was placed in the Quad Cities U and 2 Technical Specifications on March 8,1976, by Amendments 24 and 23, respectivel and was intended to remain in effect only until modifications which would-l acceptably m;t ate the effects of postulated high energy line breaks outside the containment were complet. The moulfications proponed for the high energy piping and accepted by the i
NRC in the Safety Evaluation accompanying the issuance of Amendments 24 and 23 to Quad Cities Units 1 and 2,,espectively, were completed in 1979. Consequently, Section 3.11/4.11 of i
the Quad Cities Technical Specifications can be deleted.
The proposed amendment request for this Technical Specification section is provided as -
follows:
1.
An Executive Summary of the Technical Specification Upgrade Program and the proposed amendment; 2.
A summary of the changes; 3.
A detailed description of the changes; 4.
CECO's evaluation pursuant to 10 CFS 50.92(c) and 10 CFR 51.21; and, S.

The proposed amendment has been reviewed and approved by CECO's on site and j
off site review in accordance with Company procedures.
The Technical Specilication Upgrade Program pro >oses changes to each section of the existing Technical Speelfications. As such, CECO reques:s that the proposed amendments be approved and issued no one document rathat than as individual sectfons. A'! proaosed 1
changes to the Technical Speelfications which are developed under this program wil be submitted to the Commission no later than September 30,1991. CECO respectfully requests-the NRC's approval of the upgraded Technical Specifications by July 1,1992.

EXECUTIVE
SUMMARY
Proposed Deletion of TS 3.11/4.11
'HIGH ENERGY PIPING INTEGRITY'
EXECUTIVE REHM&BY QUAD CITIES TECHNICAL SPECIPICATION UPGPADE PROGRAM The Quad Cities Technical Specification Upgrade Program was conceptualized in response to lessons learned from the Drooden Diagnostic Evaluation Team inspection and the frequent need for Technical Specification interpretations.
A comparison of the existing Quad cities Technical Specification and Standard Technical Specifications and later operating plants' Technical Specification provisions was conducted to identify potential improvements in clarifying requirements and to identify requirements which are no longer consistent with current industry practicos.
The comparison review identified approximately one-hundred and fifty suggested improvements.
The Technical Specification Upgrade Program was not intended to be a complete adoption of the Standard Technical Specifications.
Overall, the Quad cities custom Technical Specifications provide for safe operation of the plant and, therefore, only a upgrade was deemed appropriate.
The comparison study revealed a mix of recommended upgrades which included the relaxation of certain existing Technical Specification requirements, the addition of su rveillances, the removal of allowances which would no longer be allowed under new plant licensing, and better definition of appropriate action requirements in the event a Limiting Condition for Operation cannot be met.
The Technical Specification Upgrade Program also implements NRC recommended line item improvements to the Technical Specifications which were issued under Generic Letters.
In response to an NRC recommendation, the Unit 1 and Unit 2 Technical Specifications are combined into one document.
To accomplish the combination of the Units' Technical Specifications, a comparison of the Unit 1 and 2 Technical Specifications was performed to identify any technical differences.
The technical differences are identified in the proposed amendment package for each section.
l The Technical Specification Upgrade Program was identified as a Station top priority during the development i
of Quad Cities Station's Performance Enhancement Program (PEP). The Technical Specification Upgrade Program's goal is to provide a better tool to Station personnel to implement their responsibilities and to ensure Quad Cities Station is l
operated in accordance with current industry practices.
The upgraded specifications provide for more safe and reliable operation of the plant.
The program improves the operator's ability to use the Technical Specifications by more clearly defining Limiting Conditions for Operations and required actions.
EXECUTIVE H)(MARY (continued)
Proposed Changes to Technical specification Section 3.11/4.11 Heigh Energy Piping Integrity" The addition of Section 3.11/4.11 (through amendmont 24 and 23, renpectively) was intended to remain in effect only until modifications which would acceptably mitigate the effects of postulated high energy line breaks outside of tt containment were completed.
Since the modifications propt i
for the high energy piping have been completed, the propose amendment deletes the section.

DESCRIPTION QE PROPOSXQ M(EEDHEHT BEQRESI PROPOSED DELETION OF SPECIFICATION 3.11/4.11 HIGH ENER: v PIPING INTEGRITY The changes proposed in this amendment request are made to delete the temporary provisions of Section 3.11/4.11.
A description of the proposed change requested is provided below.
The Summary of Changes section can be referred to in order to reference bacx to a given change and its affected page.
Item 1 Present Section. 11/4.11, High Energy Piping Integrity (Outside Containment) was placed in the Quad Cities Units 1 and 2 Technical Specifiestions on March 8, 1976, by Amendments 24 and 23, respectively.
The addition of Section 3.11/4.11 was intended to remain in ef fe.c only until modifications which would acceptably mitigate the effects of postulated high energy line breaks outside the containment were completed.
The additional Surveillance Requirements added to the Technical Specifications in Table 4.11-1 affected portions of piping in the Main Steam System, Reactor Feedwater Piping,'HPCI Steam Piping and RCIC Steam Piping.
The Safety Evaluation accompanying the 1asuance of Amendments 24 and 21 to Quad Cities Units 1 and 2, respectively, evaluated and accepted the modifications to be made to the piping.
Since the modifications proposed for the high energy piping were completed in IV 7, Section 3.11/4.11 of the Quad Cities Technical Spec._ications can be deleted.
