3.0 STEP BASES STEPS LPC-1 and LPC-2 LEVElJPOWER CONTROL LPC-l

• A REACTOR SCRAM IS REQUIRED AND REACTOR POWER IS ABOVE 2',4 OR CANNOT BE DETERMINED

• REACTOR WATER LEVEL IS LESS THAN 1G61NCHES

• REACTOR PRESS IS ABOVE 1060 PSIG

• ORYWELL PRESS IS ABOVE 1.7 PSIG

• REACTOR SCRAM REQUIRED BY EOP- 02* pcep, EOP* 03-secp, OR EOp* 04-RRCP LPC-2 STEP BASES:

The Level/Power Control procedure (LPC) is entered from the Reactor Scram Procedure (RSP). The LPC is entered from the Primary Containment Control Procedure, Secondary Containment Control Procedure, or Radioactivity Release Control Procedure when Emergency Depressurization is required. In addition, the Reactor Flooding Procedure returns the operator to the LeveVPower Control procedure when reactor water level can be determined, and the reactor is not shutdown on control rods alone.

The conditions which require entry to Level/Power Control procedure are symptomatic of an emergency or conditions which, if not corrected, could degrade into an emergency. The entry conditions relate directly to the key parameters controlled in the RPV Control Guideline. The low reactor water level and high reactor pressure entry conditions are directly related to the sections for controlling these same two parameters. The high drywell pressure entry condition is indicative of a line break occurring in the drywell and thus relates to reactor water level control. A condition which requires a reactor scram coincident with the reactor not shutdown is indicative of a failure to scram, and thus relates directly to reactor power control. The reactor scram required by the Primary Containment Control Procedure, the Secondary Containment Control Procedure, or the Radioactivity Release Control Procedure, entry condition, 1001-37.5 Rev. 8 Page 5 of 90 I

STEP LPC-5 IF A REACTOR SCRAM HAS NOT BEEN INITIATED THEN INSERT A MANUAL SCRAM I

STEP BASES:

LPC*5 This step specifically addresses the potential for multiple sensor and sensor relay failures in the automatic RPS logic where an automatic reactor scram should have initiated but did not. A manual scram is inserted to verify an automatic action which should have taken place.

STEPS LPC-6 through LPC-9 TERMINATE BORON INJECTION LPC*7 GO TO "REACTOR VESSEL CONTROL PROCEDURE" IEOP* 01* RVCPI LPC*8 YES YES TABLE 5 ARE ALL CONTROL RODS INSERTED TO OR BEYOND POSITION 00 SHUTDOWN WITHOUT BORON ONLY ONE CONTROL ROO NOT FULLY INSERTED NO MORE THAN 10 CONTROL RODS WITHDRAWN TO POSITION 02 AND NO CONTROL ROD WITHDRAWN BEYOND POSITION 02 AS DETERMINED BY REACTOR ENGINEERING STEP BASES:

Positive confirmation that the reactor will remain shutdown under all conditions is best obtained by determining that no control rod is withdrawn beyond position 00 (Maximum Subcritical Banked Withdrawal Position). The Maximum Subcritical Banked Withdrawal Position is defined to be the lowest control rod position to which all control rods may be withdrawn in bank and the reactor will, nevertheless, remain shutdown under all conditions. The reactor will also remain shutdown under all conditions with any control rod full-out and all other control rods full-in.

Other criteria may be employed to determine that the reactor will remain shutdown, such as compliance with the Technical Specification requirements governing control rod position and the allowable number of inoperable control rods, etc. The Nuclear Engineers are contacted in order to make this determination. Design calculations have determined that the reactor will remain shutdown under all conditions with 10 control rods withdrawn to position 02 and no control rod withdrawn beyond position 02. Table 5 has been added to the flow chart to provide an easy method of listing items which can be used to determine that the reactor will remain shutdown under all conditions without boron.

1001-37.5 Rev. 8 Page 9 of 90I

STEP LPC-10 EXECUTE RCIL, RCfP AND RC/Q CONCURRENTLY LPC-10 STEP BASES:

Concurrent control of the three identified key reactor parameters is required when taking action to control and stabilize anyone, Reactor water level cannot be stabilized and maintained within a specified band if reactor pressure is oscillating. Reactor pressure cannot be stabilized and adequately controlled if reactor power is varying.

The thermodynamic and neutronic interrelationships between reactor power, reactor pressure, and reactor water level require that these three parameters be controlled concurrently.

The symptomatic approach to emergency response, upon which the EPGs are based, precludes being able to establish in advance a priority for executing any of the parallel action paths of the Level/Power Control procedure. Rather, current values and trends of parameters and the status of plant systems and equipment dictate the relative importance of individual Level/Power Control procedure steps and the relative priority with which each should be accomplished.

1001-37.5 Rev. 8 Page 11 of 90 I

STEPS RC/Q-01 and RC/Q-02 RClQ*01 AFTER STEAM FLOW IS LESS THAN 3X10' LBlHR PLACE REACTOR MODE SWITCH TO SHUTDOWN RC/Q*02 STEP BASES:

When the reactor mode switch is placed in the SHUTDOWN position, a diverse and redundant reactor scram signal is generated by the RPS logic. Sets of contacts momentarily open which trip the RPS logic in the same manner as sensor or sensor relay contacts. However, placing the mode switch to the SHUTDOWN position can also produce an adverse plant response, i.e., if the mode switch is taken out of the RUN position prior to reactor pressure decreasing to 835 psig, the MSIV closure due to low main steam line pressure is prevented. However, if the mode switch is taken out of the RUN position when the steam flow is above 33%, (on Unit 2) the MSIVs will close.

Therefore, the operator is required to place the mode switch to the SHUTDOWN position after steam flow has decreased to less than 3 x 106 Ib/hr on Unit 2 only. This equipment design does not apply on Unit 1.

1001-37.5 Rev. 8 Page 77 of 90I

STEP RCtO-03 IF ARI HAS NOT BEEN INITIATED THEN MANUALLY INITIATE ARI I

RC/Q*03 STEP BASES:

Initiating ARI is an additional redundant means of inserting a scram. This may be sufficient to terminate the ATWS and shut down the reactor.
