Subject:

Oconee Nuclear Station Docket Numbers 50-269, 270, and 287 Technical Specification Bases (TSB) Change Please see attached corrected version of Bases Page B 3.3.8-12 which was inadvertently changed when TS Bases Change 2003-05 was implemented on July 22, 2003.

Attachment 1 contains the new TSB pages and Attachment 2 contains the markup version of the Bases pages.

If any additional information is needed, please contact Larry E icholson, at (864-885-3292).

Reyes, Regional Administrator U. S. Nuclear Regulatory Commission - Region II Atlanta Federal Center 61 Forsyth St., SW, Suite 23T85 Atlanta, Georgia 30303 Mel Shannon Senior Resident Inspector Oconee Nuclear Station Mr. Henry Porter Director Division of Radioactive Waste Management Bureau of Land and Waste Management Department of Health & Environmental Control 2600 Bull Street Columbia, SC 29201 PAM Instrumentation B 3.3.8 BASES LCO 19. LP System Row (continued)

LPI System Flow Instrumentation Is a Type A, Category 1 variable provided to support action for long term cooling requirements, to prevent LPI and Reactor Building Spray pump runout. The Indication Is also used to Identify an LPI pump operating at system pressures above Its shutoff head. Flow measurement Is provided by one channel per train with readout on an indicator and recorder. There are two LPI trains. The LPI channels provide flow Indication over a range of 0 to 6000 gpm.

20. Reactor Building Sprav Flow For Unit 1, Reactor Building Spray Flow Instrumentation Isa Type A, Category 1 variable provided to support action for long term cooling requirements and iodine removal and to prevent Reactor Building Spray and LPI pump runout. For Units 2 and 3, Reactor Building Spray Flow instrumentation Isa Type D, Category 1 variable provided to support action for long term cooling requirements and Iodine removal. For Units 2 and 3, no operator action Is required for throttling Reactor Building Spray flow. Flow measurement Is provided by one channel per train with readout on an Indicator and recorder. There are two RBS trains.

The channels provide flow Indication over a range from 0 to 2000 gpm (for Unit 1) and 0 to 1500 gpm (for Units 2 and 3).'

Category 1 non-Type A Instruments must be retained in the Technical Specifications because they are Intended to assist operators In minimizing the consequences of certain events.

21. Emeraency Feedwater Flow EFW Flow instrumentation Is a Type D, Category 1 variable provided to monitor operation of RCS heat removal via the SGs.

Two channels provide indication of EFW FRow to each SG over a range of approximately 100 gpm to 1200 gpm. Redundant monitoring capability Is provided by the two Independent channels of instrumentation for each SG. Each flow transmitter provides an Input to a control room Indicator. One channel also provides Input to a recorder.

EFW Flow Isthe primary indication used by the operator to verify that the EFW System Is delivering the correct flow to each SG.

However, the primary Indication used by the operator to ensure an adequate Inventory Is SG level.

LPI System Flow instrumentation is a Type A, Category 1 variable provided to support action for long term cooling requirements, to prevent LPI and Reactor Building Spray pump runout. The A indication is also used to identify an LPI pump operating at system ,

For Units 2 and 3, pressures above its shutoff head. Flow measurement is provided Reactor Building by one channel per train with readout on an indicator and Spray Flow recorder. There are two LPI trains. The LPI channels provide instrumentation is a flow indication over a range of 0 to 6000 gpm.

Type D, Category I variable provided to 2 F For Unit 1 support action for 20. Reactor Building SDrav Flow long term cooling 4Jeactor Building Spray Flow instrumentation is a Type A, requirements and Category 1 variable provided to support action for long term iodine removal. For cooling requirements and iodine removal and to prevent Reactor Units 2 and 3, no operator action is Building pray and LPI pump runout. Flow measurement is required for throttling provided by one channel per train with readout on an indicator and Reactor Building recorder. There are two RBS trains. The channels provide flow Spray flow. indication over a range from 0 to 2000 gp (for Unit 1) and 0 to 1500 gpm (for Units 2 and 3).

21. Emergency Feedwater Flow EFW Flow instrumentation is a Type D, Category 1 variable provided to monitor operation of RCS heat removal via the SGs.

Two channels provide indication of EFW Flow to each SG over a range of approximately 100 gpm to 1200 gpm. Redundant monitoring capability is provided by the two independent channels of instrumentation for each SG. Each flow transmitter provides an input to a control room indicator. One channel also provides input to a recorder.

EFW Flow is the primary indication used by the operator to verify that the EFW System is delivering the correct flow to each SG.

However, the primary indication used by the operator to ensure an adequate inventory is SG level.
