y 1.1 The purpose of this procedure is to provide methods for 4
determining SHUTDOWN MARGIN to verify it is greater thr.n the limits of Technical Specifications 4.1.1.1.1 I
c; 4.1.1.2 as applicable.
l 1.2 Verification of SHUTDOWN MARCIN
- .s required:
a.
When in Modes 1, 2, 3, 4 or 5 within one hour after detection of an inoperable Control Rod and each 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> thereafter while the control Rod is
)
b.
Trior to initial operation above 5% Rated Thermal Power after each fuel loading.
i
(*
c.
When in Modes 3, 4, or 5 at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
~
1.3 This procedure also provides instructions for determining the Kaff of the reactor in its present state or predicting its value at future plant conditions.
2.0 APPLICABILITY This procedure.is applicable in Operational Modes 1, 2, 3, 4, 5 and 6.
t 3.0 PRECAUTIONS AND LIMITATIONS 3.1 Xenon Worth provided by refirence curves assumes equilibrium conditions prior to shutdown.
If plant was in a transient condition, obtain Xenon Worth from plant computer or calculate Xenon Power using the form provided by PTDB TAB 1.4.3.
3.2 If boration or dilution evolutions are or have been occurring, care shall be taken to ensure representative RCS boron samples are used for chemical analysis.
3.3 No credit is taken for Samarium reactivity since the negative reactivity introduced by Samarium 149 buildup is offset by an equal positive reactivity introduced by the buildup of Plutonium 239.
