4.2.3.2 The combination'of indicated RCS total flow rate and R, R, shall be' 3

i determined to be within the region of acceptable operation of Figurn 3.2-3:

a.

Prior to operation above 75% of RATED THERMAL POWER after each fuel loading, and b.

At least once per 31 Effective Full Power Days.

4.2.3.3 The indicated RCS total flow rate shall be verified.to be within the region of acceptable operation of Figure 3.2-3 at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> when the most recently obtained values of R and R, obtained per Specification y

2 4.2.3.2, are assumed'to exist.
