ENCLOSURE PROPOSED CHANGE NPF-38-09 1.
Provide the amount of margin credited during CPC monitoring for each of the following:
a) reduced modeling uncertainty over a narrower LC0 ASI Band b) credit for transient offset terms c) credit for additive power measurement uncertainty d) credit for conservatism of neutron flux power relative to thermal power e) credit for dynamic pressure uncertainty in CPC f) credit for the Update penalty factor in CPC 2.
Explain how the COLSS out-of-service DNBR limit line is derived (Fig. 3.2-2 and Fig. 3.2-3).
3.
Why is there no difference between Fig. 3.2-2 (for COLSS out-of-service and CEACs operable) and Fig. 3.2-3 (for COLSS out-of-service and CEACs inoperable)?
4.
The Bases for LHR states that a penalty factor of 57% is applied in CPC when COLSS is out-of-service and both CEACs are inoperable. How is this penalty determined and how is it applied in the CPC? Is the penalty cycle dependent?
5.
Should Surveillance Requirement 4.2.1.2 refer to Figure 3.2-a rather than 3.2-1?
PROPOSED CHANGE NPF-38-12 1.
Please comment on whether present or future cycles may contain MTC values which are not necessarily most positive at BOL.
If so, the surveillance requirement?should be worded so as to perform a con-firmatory measurement near the cycle time of maximum positive MTC.
