Enclosure Technical Specification 3.8.A.4 should be revised to read as follows:
"3.8.A.4 With the reactor vessel head closure bolts less than fully tensioned or with the head removed, the more restrictive of the following reactivity conditions shall be met:
- a. A shutdown margin greater than 5% a K/K
- b. A boron concentration greater than or equal to 2,000 ppm."
The first paragraph of the Basis for Technical Specification 3.8 should be revised as follows:
"Basis During refueling, the reactor refueling cavity is filled with approximately 240,000 gallons of borated water whose concentration is sufficient to maintain the reactor subcritical by greater than 5% A K/K or to a boron concentration greater than or equal to 2,000 ppm, whichever is more restrictive. Operation of one method of decay heat removal is provided to assure continuous mixing flow of refueling water through the reactor vessel during the refueling period.(1) Borated water injection capability is provided as per Specification 3.2 Part A in the unlikely event there is any need during the refueling period."
