1.0 DEFINITIONS (Cont'd)

H. Reactor power Operation - Reactor power operation is any operation with the mode switch in the "Startup" or "Run" position with the reactor critical and above 1 percent rated power.

I. Hot Standby Condition - Hot standby condition means operation with coolant temperature greater than 212 0F, system pressure less than 1,055 psig, the main steam isolation valves closed and the node switch in the Startup/ Hot Standby position.

J. Cold Condition - Reactor coolant temperature equal to-or less than 2120F.

K. Hot shutdown - The reactor is in the shutdown mode and the reactor coolant temperature greater than 212 0F.

L. Cold Shutdown - The reactor is in the shutdown mode and the reactor coolant temperature equal to or less than 212 0F.

M. Mode of Operation - A reactor mode switch selects the proper interlocks for the operational status of the unit. The fc11owing are the modes and interlocks provided:

1. Startup/ Hot Standby Mode - In this modo the reactor protection scram trips initiated by condenser low vacuum and main steam line isolation valve closure, are bypassed when reactor pressure is less than 1,055 psis, the reactor protection system is energized with IRM neutron monitoring system trip, the ApRM 15 percent high flux trip, and control rod withdrawal interlocks in service. This is of ten referred to as just Startup Mode. This is intended to imply the Startup/ Hot Standby position of the node  ;

switch. ]

2. Run Mode - In this mode the reactor system pressure is at or above 825 psis and the reactor protection system is I energized with ApRM protection (excluding the 15 percent high flux trip.) and the RBM interlocks in service.

)

3. Shutdown Mode - placing the mode switch to the shutdown position initiates a reactor scram and power to the control rod drives is removed. After a short time period (about 10 sec), the scram signal is removed allowing a scram reset and restoring the normal valve lineup in the  ;

control rod drive hydraulic system; also, the main steam line isolation scram and main condenser low vacuum scram are bypassed if reactor vessel pressure is below 1,055 ,

psis.

4. Refuel Mode - With the mode switch in the refuel position, interlocks are established so that one control rod only may be withdrawn when the Source Range Monitor indicates at least 3 cps and the refueling crane is not over the l reactor; also the main steam line isolation scram and main l condenser low vacuum scram are bypassed if the reactor i l

vessel pressure is below 1,055 psig. If the refueling crane is over the reactor, all rods nust be fully inserted and none can be withdrawn.

1.0 DEFINITIONS (Cent'd)

N. Rated power - Rated power refers to. operation at a reactor power of

  • 3,293 MWt; this is also termed 100 percent power and is the maxinum power level authorized by the operating license. Rated steam flow, rated coolant flow, rated neutron flux, and rated nuclear system pressure refer to the values of these parameters when the reactor is at rated power. Design power, the power to which the safety analysis applies, corresponds to 3,440 MWt.

O. Primary Containment Intentrity - primary containment integrity means that the drywell and pressure suppression chamber are intact and all of the following conditions are satisfied:

1. All nonautomatic containment isolation valves on lines connected to the reactor coolant systems or containment which are not required to be open during accident conditions are closed.

These valves may be opened to perform necessary operational' activities.

2. At least one door in each airlock is closed and sealed.
3. All automatic containment isolation valves are operable or each line which contains an inoperable isolation valve is isolated as required by specification 3.7.D.2.
4. All blind flanges and manways are closed.
