. REACTIVITY CONTROL SYSTEMS MODERATOR TEMPERATURE COEFFICIENT LIMITING CONDITION FOR OPERATION 3.1.1.3 -The moderator temperature coefficient (MTC) shall be:
-4 a.
Less positive than 0.5 x 10 delta k/k/*F whenever THERMAL POWER is < 70% RATED THERMAL POWER, and
-4 b.
Less positive than 0.0 x 10 delta k/k/*F whenever THERMAL POWER is > 70% RATED THERMAL POWER, and
~4 c.
Less negative than -3.3 x 10 delta k/k/*F at all levels of thermal power.
APPLICABILITY: MODES 1 and 2*#
ACTION:
1 With the moderator temperature coefficient outside any one of the above limits, be in at least HOT STANDBY w.ithin 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
SURVEILLANCE REQUIREMENTS 4.1.1.3.1 The MTC shall be determined to be within its limits by confirmatory measurements. MTC measured values shall be extrapolated and/or compensated to permit direct comparison with the above limits.
4.1.1.3.2 The MTC shall be determined at the following frequencies and THERMAL POWER conditions during each fuel cycle:
Prior to initial operation above 5% of RATED THERMAL POWER, after a.
each fuel loading.
b.
At greater than 15% of RATED THERMAL POWER, prior to reaching 40 EEPD core burnup.
At any THERMAL POWER, within 7 EFPD of reaching two-thirds o'f c.
expected core burnup.
i "With K,ff greater than or equal to 1.0.
