LIMITING CONDITION FOR OPERATION 3.1.1.4 The moderator temperature coefficient (MTC} shall be:
- a. < 0.5 x 10-4 Qk/k/oF below 70 percent RATED THERMAL POWER 0.0 x 10-4 gk/k/oF at or above 70 percent RATED THERMAL POWER.
- b. Less negative than -3.9 x 10 ak/k/'F for the all rods withdrawn, end of cycle life (EOL), RATED THERMAL POWER condition.
APPLICABILITY: Specification 3.1.1.4.a - MODES 1 and 2>>
3.1.1.4.b - MODES 1, 2 and 3only'pecification only'CTION:
- a. Mith the MTC more positive than the limit of 3.1.1.4.a above:
