Attachment:

Changes to the Technical Specifications Date of Issuance: April 4, 1984

ATTACHMENT TO LICENSE AMENDMENT AMENDMENT NO.

79 FACILITY OPERATING LICENSE NO. DPR-23 DOCKET NO. 50-261 Revise Appendix A as follows:

Remove Pages Insert Pages 3.6-1 3.6-1 3.6-2a 3.6-2a

3.6 CONTAINMENT SYSTM Analicability Applies to the integrity of reactor containment.

Obective To define the operating status of the reactor containment for plant operation.

Soecification 3.6.1 Containment Integrity

a.

The containment integrity (as defined in 1.7) shall not be violated unless the reactor is in the cold shutdown condition.

b.

The containment integrity shall not be violated when the reactor vessel head is removed unless a shutdown margin greater than 10% Ik/k is constantly maintained.

c.

Positive reactivity changes shall not be made by rod drive mction when the containment incagrity is not intact except for rod drop tests or disconnecting part length rods, in which case the shutdown margin is maintained >1. dk/k.

d.

Positive reactivity changes shall not be made by boron dilution when the containment integrity is aot intact unless the shutdown margin is maintained >L k/k.

3.6.2 Tternal ?ressure If the interal pressure exceeds I psi or the internal vacuum exceeds 1.0 psi, the condition shall be corrected within eight (3) hours or the 3.6-1 Amendment No. 79

Regarding internal pressure limitations, the containent design pressure of 42 psig would not be exceeded if the internal pressure before a major loss-of-coolant accident were as much as 2 psig.

The containent is designed to withstand an internal vacuum of 2.0 pai. (2)
