LIMITING CONDITION FOR OPERATION 3.6 PRIMARY SYSTEM B0UNDARY Apolicability:
Applies to the operating status of the reactor coolant system.
Obiective:
To assure the integrity and safe operation of the reactor coolant system.
Soecification:
A.
Thermal limitations 1.
The average rate of reactor coolant temperature change during normal heatup or cooldown shall not exceed 100*F in any one-hour period.
2.
At all times, the shell flange to shell temperature differential shall not exceed 140*F.
SURVEILLANCE REQUIREMENT 4.6 PRIMARY SYSTEM B0UNDARY Apolicability:

LIMITING CONDITION FOR OPERATION 3.6 PRIMARY SYSTEM BOUNDARY 3.6.B.2.
Normal Heatuo and Cooldown and low-level Physics Tests During heatup by non-nuclear (mechanical) means, cooldown following nuclear shutdown, and low-level physics tests, the reactor vessel shell and fluid temperatures at the locations stated in Specification 4.6.A.1 shall be at or to the right of the curve shown in Figure 3.6.2.
3.
Core Criticality i
During all operation with a critical core, except for low-level ohysics tests, the reactor vessel shell and fluid temperatures at the locations stated in Specification 4.6.A.1 shall be at or to l
the right of the curve shown in Figure 3.6.3.
4.
Reactor Vessel Head Stud Tensionina The reactor vassel head bolting studs shall not be under tension unless the temperature of the vessel head flange and the head is greater than 86'F.
j SURVEILLANCE REQUIREMENT 4.6.B.2.
Normal Heatuo and Cooldown and Low-level Physics Tests During heatup by non-nuclear means, cooldown following nuclear shutdown, and low-level physics tests, the reactor vessel shell and flyid temperatures at the locations stated in Specification 4.6.A.1 l
shall be permanently recorded every 15 minutes.
3.
Core Criticality During operation with a critical core (except for low-level physics tests), the reactor vessel sh_qll and fluid temperatures at the 1
locations stated in Specification 4.6. A.1 shall be permanently recorded, except for periods of maintenance on the monitoring equipment not to exceed 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, provided that no heatup or cooldown evolution is in progress.
4.
Reactor Vessel Heat Stud Tensionina When the reactor vessel head bolting studs are tightened or loos-ened, the reactor vessel head flange and head temperatures shall be permanently recorded.
