1 GPU NUCLEAR CORPORATION OYSTER CREEK NUCLEAR GENERATING STATION (DOCKET NO. 50-219)

PROVISIONAL OPERATING LICENSE NO. DPR-16

- Applicant hereby requests the commission to change Appendix A of the above captioned license as follows:

1. Sections to be changed:

a. Section 3.5 b..Section 3.5 Bases

c. Section 4.5 Bases

2. Extent of changes:-

a. Section 3.5 Containment Specification 3.5.A.6 for primary containment atmosphere is being revised to reflect an oxygen concentration of less than 5% within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and less than 4% within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> after the reactor mode switch is placed in the run mode,

b. Section 3.5 Bases The bases are being revised to reflect the 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> overall inerting time interval and the origin of the 4% 02 limit. The appropriate reference has been added.

c. Section 4.5 Bases These bases are being revised to correct a typographical error.

3. Change requested:

The requested change is on the attached revised Technical Specification pages 3.5-3, 3.5-5, 3.5-6, 3.5-7 and 4.5-10.

4. Discussion:

Specification 3.5.A.6 cites the requirements for the oxygen concentration limits for the primary containment atmosphere. The purpose of this Technical Specification change request is to reduce the limit for oxygen concentration in the primary containment '

atmosphere from less than 5% 02 to less than 4% 02 and to increase the overall inerting time interval from 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.

This change request results from an analysis performed by General Electric on the Generation and Mitigation of Combustible Gas Mixtures in Inerted BWR Mark I Containments. This analysis, General Electric NEDO 22155 June 1982, was prepared for the BWR Owner's Group in response to 100FR50.44, the final Interim Requirements Related to Hydrogen Control which was published in the Federal Register on December 2, 1981.

OYSTER CREEK NUCLEAR GENERATING STATION PROVISIONAL OPERATING LICENSE N0. DPR-16 DOCKET N0. 50-219 TECHNICAL SPECIFICATION CHANGE REQUEST N0. 112 Pursuant to 10CFR30.91, an analysis concerning significant hazards considerations is provided below:

1. Section to be changed:

3.5, 3.5 Bases and 4.5 Bases

2. Extent of change:

a. Section 3.5 Containment Specification 3.5.A.6 for primary containment atmosphere is being revised to reflect an oxygen concentration of less than 5% within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and less than 4% within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> after the reactor mode switch is placed in the run mode,

b. Section 3.5 Bases The bases are being revised to reflect the 48 hour5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> overall inerting time interval and the origin of the 4% 02 limit. The appropriate reference has been added.

c. Section 4.5 Bases These beses are being revised to correct a typographical error.

3. Change requested:

The requested change is on the attached revised Technical Specification pages 3.5-3, 3.5-5, 3.5-6, 3.5-7 and 4.5-10.

4. Discussion:

Specification 3.5.A.6 cites the requirements for the oxygen concentration limits for the primary containment atmosphere. The purpose of this Technical Specification change request is to reduce the limit for oxygen concentration in the primary containment-atmosphere from less than 5%

02 to less than 4% 02 and to increase the overall inerting time interval from 24 hc vs to 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />..

This change request results from an analysis perfonned by General Electric on the Generation and Mitigation of Combustible Gas Mixturei in Inerted BWR Mark I Containments. This analysis, General Electric NEDO 22155 June 1982, was prepared for the BWR Owner's Group in response to 10CFR50.44, the final Interim Requirements Related to Hydrogen, Control which was published in the Federal Register on December 2, 1981.

5.: Detennination:

We have determined that this proposed amendment involves a change that constitutes.an additional limitation, restriction, or control not presently included in the technical specifications. Specifically, this

~

requested change will revise the oxygen concentration in the primary containment atmosphere from the present limit of less than 5% 02 to a more stringent limit of less than 4% 0 2-1 Based on the above, operation of-the Oyster Creek Nuclear Generating Station in~accordance with Technical Specification Change Request No. 112 would not:

1. Involve a significant increase in the probability or consequence of an

. accident previously.eva?'ated; or

2. Create the possibility of a new or different kind of accident froni any

accident previously evaluated; or

3. Involve a significant reduction in a margin of safety.
