With a PDMS inoperability, the following 4 TSs are impacted because they utilize PDMS for auto calculations:
3.2.1 Heat flux hot channel factor
3.2.2 Nuclear enthalpy rise hot channel factor
3.2.4 QPTR
3.2.5 DNBR spec not applicable when PDMS inoperable
MODE 1 with THERMAL POWER >= 50% RTP when Power Distribution
Monitoring System (PDMS) is OPERABLE.
PDMS readings are color coded as follows:
Green TS satisfied
Yellow <2% of TS limit
Red exceeding TS limit
Safety functions in order;
Subcriticality (s) Core cooling (c) Heat removal (h) Rcs integrity (p) Containment integrity (Z) Inventory (I)
RTP=_____MwT
