Subject:
Oyster Creek Nuclear Generating Station Docket No. 50-219 Technical Specification Change Request No.164 Pursuant to 10CFR50.90, GPU Nuclear Corporation, operator of the Oyster Creek Nuclear Generating Station (0CN3S), Provisional Operating License No. OPR-16, requests a change to Appendix A of that license.
The attached Technical Specification Change Request proposes to delete safety limit 2.1.E.
This safety limit requires at least two recirculation loops to be fully open except when the reactor vessel head is off and vessel water level is above the main steam nozzles.
The purpose of the safety liinit is to ensure adequete fluid comunication between annulus and core regions in the reactor vessel so that water level sensed %n the annulus is indicative of water level in the core.
We Delieve that this limitation is more appropriately a limiting condition for operation which would be incorporated in Technical Sper'fication Section 3.3.F.
We also propose to revise this limitation to require that at least one recirculation loop instead of two be fully open during applic#ia plant conditions.
Analysis has shown that one fully open recircula ~ )n loop provides adequate hydraulic comunication during the limiting transient.
In addition, a revised specification to allow isolation of all recirculation loops is proposed.
This specification would incorporate limitations on reactor coolant temperature and level in the vessel to ensure that hydraulic communication between annulus and core regions exists above the core. Witt, hydraulic comunication established above the core region, adequate core region water level monitoring is assured and all recirculation loops can be isolated. These changes are requested so that requirements for recirculation loop operation are consistent with the safety limit and limiting condition for operation definitions in 10CFR50.36, are appropriate for different plant conditions and reflect the results of analysis performed.
In addition to the proposed cha,1ges summarized above, we are proposing changes to specifications 3.3.F.1, 3.3.F.2 and 3.3.F.3.
The changes to specifications 3.3.F.1 and 3.3.F.2 are editorial and are intended to f 00 I 8804190274 880331

provide greater clarity regarding the plant condition during which they apply.
Specification 3.3.F.3 is an action requirement which requires the plant to be placed in the cold shutdown condition within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> if less than four recirculation loops are operating during power operation.
Our proposed change for specification 3.3.F.3 would require the plant to be placed in a hot shutdown condition within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. A basis is provided for specifications 3.3 F.1, 3.3.F.2 and 3.3.F.3 because it is not l
currently incorporated. A typographical error has been identified in tha basis for specification 2.1.0 and will be corrected.
We request the NRC staff to place an appropriate priority for a timely review of these proposed Technical Specification changes.
If approved, we would be prepared to implement the changes upon issuance of the license amendment.
This change request has been reviewed in accordance with Section 6.5 of the OCNGS Technical Specifications, and using the standards in 10CFR50.92
+
we have concluded that these proposed changes do not constitute a significant hazards consideration.
Pursuant to 10CFR50.91(b)(1), a copy of this change raquest has been sent to the State of New Jersey Department of Environmental Protection.
In addition, a check for $150.00, pursuant to 10CFR170.12, is enclosed for the application fee.
