The reactor shall not be made critical unless the two pressurizer safety /alves are operable with their lift settings adjusted to ensure valve opening between at 2500 psia ib.L5 and 2545 psia 11E("
(2)
Whenever there is fuel in the reactor, and the reactor vessel hcad is installed, a minimum of one operaole safety valve shall be installed on the pressurizer, llowever, when in at least the cold shutdown conditlen, safety valve noules may be open to containment atmospherc during performance of safety valve tests or maintenance to satisfy this specification.

Specif&caftens To provide adequate overpressure protection for the reactor coolant systcm and steam system, the following safety valve requirements shall be met:
(1)
The reactor shall not be made critical unless the two pressurizer safety valves are operable with their lift settings adjusted to ensure valve opening at 2500 psia 1% and 2545 psia il%.*
(2)
Whenever there is fuel in the reactor, and the reactor vessel head is installed, a minimum of one operable safety valve shall be installed on the pressuriter.
