Public Service Electric and Gas Company Joseph J. Hagan Public Service Electric and Gas Company P.O. Box 236, Hancocks Bridge, NJ 08038 609-339-1200 Vice President - Nuclear Operations MAY 0 3 1994 NLR-N94048 LCR 94-08 United States Nuclear Regulatory Commission Document Control Desk Washington, DC 20555 Gentlemen:
REQUEST FOR AMENDMENT COMBUSTIBLE GAS CONTROL AND AUXILIARY FEEDWATER SYSTEM SALEM GENERATING STATIONS UNIT NOS. 1 AND 2 DOCKET NOS. 50-272 AND 50-311 In accordance with the requirements of 10CFR50.90, Public Service Electric & Gas Company (PSE&G) hereby transmits a request for amendment of Facility Operating Licenses DPR-70 and DPR-75 for Salem Generating Station Units Nos. 1 and 2 respectively.
In accordance with 10CFR50.91(b) (1) requirements, a copy of this request has been sent to the State of New Jersey.
The proposed amendment modifies two Technical Specifications.
First, the proposed amendment modifies Technical Specification 3/4.6.4.1 for Combustible Gas Control.
This change modi'f~es the surveillance frequency for performing the channel functional test to once per quarter and the channel calibration to once per~,
refueling.
The proposed amendment also modifies Technical Specification 3/4.7.1.2 for ~uxiliary Feedwater system.
This change modifies the surveillance frequency for performing the pump operability test to once per quarter on a staggered test basis.
This change was approved for Virginia Power Corporation's North-Anna Power Station on February 7, 1994.
The requested changes are consistent with Generic Letter 93-05, Line-Item Technical Specifications Improvements to Reduce Surveillance Requirements For Testing During Power Operation and NUREG-1366, Improvements to Technical Specification Surveillance Requirements.
Operating experience at Salem Units 1 and 2 is compatible with the requested changes in surveillance frequencies.

Description of Change A.
Change Surveillance Requirement 4.6.4.1 to read:
LCR 94-08
"*** a CHANNEL FUNCTIONAL TEST at least once per 92 days, and at least once per refueling by performing a CHANNEL CALIBRATION using sample gases containing:"
B.
Change sur\\reillance:Requirement 4.7.1.2 as follows:
- 1.
Re-number 4.7.1.2.a.3 as 4.7.1.2.a.1 and 4.7.1.2.a.4 as
- 4. 1. 1~ 2'.. a*. 2 _,
- Place. these. surveillances after 4.7.1.2.a.
- 2.
Insert new 4.7.1.2.b to read:
"At least once per 92 days on a STAGGERED TEST BASIS by:".
Re-number 4.7.1.2.a.1 as 4.7.1.2.b.1 and 4.7.1.2.a.2 as 4.7.1.2.b.2.
Place these surveillances after 4.7.1.2.b.
- 3.
Change the number for 4.7.1.2.b to 4.7.1.2.c.
- II.
Justification A.
Technical Specification 4.6.4.1 Hydrogen analyzers are used to monitor hydrogen concentration in the containment following a Loss of Coolant Accident (LOCA) and are designed to be consistent with NUREG-0737, Clarification of TMI Action Plan Requirements.
These monitors are used only after a LOCA to tell the operator when to initiate the hydrogen recombiners.
The hydrogen recombiners are not required for a period of hours to days after a large-break LOCA.
The current Salem Unit Nos. 1 and 2 Technical Specifications require a channel check at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, *a channel functional test at least once per 31 days, and a channel calibration at least once per 92 days using two sample gases one containing two volume percent hydrogen and one containing six volume percent hydrogen.
The monthly tests check only the electronics.
The quarterly test check calibration.
NLR-N94048
- 2 LCR 94-08 There are other operability checks of the system.
There are alarms to indicate electronic and power failures.
In addition, Operations personnel monitor the indications daily and would note any changes.
Operating experience at Salem Unit Nos. 1 and 2 for the hydrogen analyzers is compatible with the proposed surveillance frequency change.
This change is consistent with Generic Letter 93-05, Line-Item Technical Specification Improvements to Reduce Surveillance Requirements For Testing During Power Operation and NUREG-1366, Improvements to Technical Specification surveillance Requirements.
B.
Technical Specification 4.7.1.2.a:
The current Salem Unit Nos. 1 and 2 Technical Specifications require monthly testing of the Auxiliary Feedwater Pumps.
The Boiler and Pressure Vessel Code of the American Society of Mechanical Engineers (ASME Code),Section XI, Paragraph IWP-3400, requires the testing of Class 1, 2*, and 3 centrifugal pumps "normally every three months."
Auxiliary Feedwater Pumps are theoilly pumps required by Technical Specifications to be tested more frequently than the ASME Code.
The Technical Specifications.do not.require testing to be as thorough. as.the ASME Code. *The.Technical Specifications only require flow rate and discharge pressure to be monitored.
The ASME Code Test requires the following parameters to be monitored:
inlet pressure, differential pressure, flow rate, vibration amplitude, and bearing temperature.
In both the Technical Specification test and the ASME Code test, the Auxiliary Feedwater pump takes a suction from a Auxiliary Feedwater Storage Tank and returns the water to the tank through a recirculation line.
The ASME Code test will provide more detailed information regarding pump condition.
Changing the test from a monthly to a quarterly test will reduce wear on the Auxiliary Feedwater pumps*.
The test to be performed will satisfy the current Technical Specification requirements as well as those identified in the ASME Code. By testing the pumps on a staggered test basis, at least one Auxiliary Feedwater Pump will be tested each month.
This testing frequency will be sufficient to maintain a consistent degree of reliability.
NLR-N94048
- 3 LCR 94-08 The proposed changes to the surveillance requirements for the Auxiliary Feedwater system are consistent with the intent of Generic Letter 93-05, Line-Item Technical Specification Improvements to Reduce Surveillance Requirements for Testing During Power Operation, and NUREG-1366, Improvements to Technical Specification Surveillance Requirements.
Operating experience at Salem Unit Nos. 1 and 2 for the Auxiliary Feedwater pumps is compatible with the proposed surveillance frequency change.
The re-numbering of surveillance requirements is necessary to incorporate the new quarterly testing frequency.
All changes associated with re-numbering are editorial.
III. In accordance with 10CFR50.92, PSE&G has reviewed the proposed changes and concluded the proposed changes do not involve a significant hazards consideration because the changes would not:
- 1.
Involve a significant increase in the probability or consequences of an accident previously analyzed.
The proposed changes to the surveillance requirements for the hydrogen analyzers and the Auxiliary Feedwater pumps are consistent with the intent of Generic Letter 93-05, Line-Item Technical Specification Improvements to Reduce Surveillance Requirements for Testing During Power Operation, and NUREG-1366, Improvements to Technical Specification Surveillance Requirements.
The proposed changes will* modify surveillance frequency for both the hydrogen analyzers and the Auxiliary Feedwater Pumps.
Changing the surveillance frequency for the hydrogen analyzers and the Auxiliary Feedwater pumps does not affect the probability of occurrence or the consequences of accidents identified in the UFSAR.
No accident precursors are being generated by the proposed increase in surveillance frequency.
Therefore, the proposed changes do not involve a significant increase in the probability or consequences of a previously analyzed accident.
NLR-N94048
- 4 LCR 94-08
- 2.
Create the possibility of a new or different kind of accident.
The proposed changes to the surveillance requirements for the hydrogen analyzers and the Auxiliary Feedwater pumps are consistent with Generic Letter 93-05 and NUREG-1366. There are no modifications or changes in operating conditions associated with the proposed changes.
Therefore, the proposed changes will not increase the possibility of a new or different kind of accident from any accident previously identified.
- 3.
Involve a significant reduction in a margin of safety.
The Technical Specification operability requirements for the hydrogen analyzers and the Auxiliary Feedwater pumps are not being changed.
Surveillance testing will still be performed on a routine frequency.
The proposed frequency will be capable of performing its intended function and ensuring a consistent degree of reliability.
Therefore, the changes to the surveillance frequencies do not involve a significant reduction in any margin of safety.
IV.
Based upon the preceding information, PSE&G has concluded that the proposed changes meet the requirements of 10CFR50.92(c) and does not involve a significant hazards consideration.
