ATTAClefENT B DESCRIPTION AND SUMMA 9Y CF PROPGC~,0 CHANGES, The proposed changes involve Technical Specification Tables 3.3-13, and 4.3-9 for the Byron and Braidwood Stations. These changes are being requested to separate the Gaseous Waste Manager.ent Syst * ?xygen Analyzer into two separate oxygen analyzers based upon how these ote operated.

The Oxygen Analyzer (OAT-GW8003) is capable of centinuously analyzing the oxygen concentration from the various source tanks lined up to the Waste Gas Compressor suction and any one of the Gas Decay Tanks, since the system has an inline pump that provides continuous flow. The Waste Gas Compressor Oxygen Analyzer (OAIT-GW004) is located on the discharge side of the Waste Gas Compressor and is capable of continuously analyzing the oxygen concentration in the Waste Gas Compressor discharge as long as one compressor is running. The proper operation of each analyzer is dependent upon adequate gas flow past the detector.

Based upon this separation of operation, the minimum of one (1) channel being operable will need only to apply during the operation of the Waste Gas Compressor for Analyzer OAIT-GWOO4. Also, a change to ACTION Statement 38 is requested to cover individual operation of each analyzer for less than the stated channels operable.

ATTACHMENT C EVALUA*fION OF SIGNIFIC13T HAZ.V?3 CONSTDERATIONS Commonwealth Edison has evaluated this proposed amendment and determined that it involves no significant hazards considerations.

According to 10 CFR 50.92(c), a proposed amendment

,an operating license involves no significant hazards considerations if operatien of the facility in accordance with the proposed amendment would not:

1)

Involve a significant increase in the probability or consequences of an accident previously evaluated; or 2)

Create the possibility of a new or different kind of accident f om any accident previously evaluated; or 3)

Involve a significant reduction in a margin of safety.

This change separates the Gaseous Waste Management System oxygen analyzers intu two analyzers based upon their application. The OAT-GW8003 analyzer is capable of continuously analyzing oxygen concentration from the various source tanks and any one of the Gas Decay Tanks. The OAIT-GWOO4 analyzer requires the Waste Gas Compressor to be in operation fcr it to function. The proposed change clarifica the functional requirements and revises the Action Statement to reflect th's change.

The changes to Table 3.3-13 made to isnarate the two oxygen analyzers into individual monitors, based on ti.wir separate application in the system does not ir-pact tne Accident Analysis of the Byron /Braidwood FSAR. Rather it more clearly defines the application and function of the two oxygen analyzers. As a result, the changes do not involve a significent increaso in the probability or consequences of an accident previously evaluated.

No physical change or modification to the Gaseous Vaste Managermont System is being made, and its intended operation as described in the FSAR will remain unchanged. The application of the two oxygen analyzers will be

.nore clearly defined by these changes. As such, the changes do not create the possibility of a new or different kind of accident from any previously analyzed.

Since, the Gaseous Waste Management System operation is not affected by this change, which is made to more clearly define the application of the two oxygen analyzers, this change does not affect the margin of safety.

Therefore, based on the above evaluation e 9onwealth Edison believes that these changes do not irivolve signifis. a hazards considerations.
