3/4.15 SPECIAL TEST EXCEPTIONS SHUT 00WN MARGIN LIMITING CONDITION FOR OPERATION 3.10.1 The SHUT 00WN MA'RGIN requirement of Specification 3.1.1.1 may be suspended for measurement of CEA worth and shutdown margin provided reactivity equivalent to at least the highest estimated CEA worth is available for trip insertion from OPERABLE CEA(s).
APPLICABILITY: MODE 2.
ACTION:
a.
With any full length CEA not fully inserted and with less than the above reactivity equivalent available for trip insertion, imsdiately initiate and continue baration at > 40 gpm of 2300 l
ppm boric acid solution or its. equivalent untiT the SHUT 00WN MARGIN required by Specification 3.1.1.1 is restored.
b.
With all full length CEAs inserted and the reactor subcritical' by less than the above reactivity equivalent, imediately

initiate and continue boration at > 40 gpm of 2300 ppm boric l
acid solution or its equivalInt until the SHUT 00WN MARGIN re-quired by Specification 3.1.1.1 is restored.
