3/4.l REACTIVITY CONTROL SYSTEMS 3/4.1.1 BORATION CONiROL SHUTDOWN MARGIN - Tavg > 200°F LIMITING CONDITION FOR OPERATION 3.1.1.1 The SHUTDOWN MARGIN shall be!. 1.6% Ak/k.
APPLICABILITY:
MODES 1.,
~'*, 3, and 4.
ACTION:
With the SHUTDOWN MARGIN*< 1.6% Ak/k, ilTIT1ediately initiate and continue boration at > 10 gpm of 20~00 ppm boric acid solution or equivalent until the required SHUTDOWN MARGIN is restored.
SURVEILLANCE REQUIREMENTS 4.1.1.l.l The SHUTDOWN MARGIN shall be determined to be!. l.6% ~k/k:

If the inoperable control rod is irrmovable or untrippable, the above required SHUTDOWN MARGIN shall be increased by an amount at least equal to the withdrawn worth of the ilTIT1ovable or untrippable con~rol rod(s).
