e REACTIVITY CONTROL SYSTEM POSITION INDICATION SYSTEM-SHUTDOWN LIMITING CONDlTION FOR OPERATION 3.1.3.3 The group step demand counter and at least two analog rod position indication channels per group shall be OPERABLE for each group of shutdown or i control rods not fully inserted.

APPLICABILITY: Modes 3*#, 4*# and 5*J ACTION:

With less than the above required position indicator (s) OPERABLE, immediately insert all rods or, immediately open the reactor trip system breakers.

SURVEILLANCE REQUIREMENTS

4.1.3.3 Each of the above required position indicator (s) shall be determined to i

be OPERABLE by performance of Specifications 4.1.3.2.1 and 4.1.3.2.2.

• With the reactor trip system breakers in the closed position.

1. The accuracy requirements of the analog rod position indication system are not applicable below Tavg of 547F due to known shif t of the calibration of the analog rod position indication system at reduced plant temperatures. At plant temperatures below Tavg = 547F, the analog rod position indicators shall be used to provide general guidance in determining rod position and the group demand indicators shall be used to determine exact rod positions. The requirements set forth in 4.1.3.2.2b must be performed at a nominal average coolant temperature of 547F. Durinb preparations for startup, the requirements of 4.1.3.2.2b may be waived until a nominal coolant temperature of 547F is reached. This exclusion for monitoring the analog to demand accuracy within the Rod Position Indication I

System at temperatures below 547F is applicable pending resolution of the analog RPI drif t between Duquesne Light and the NRC. This issue is expected to be resolved during July 1982.
