r" ENCLOSURE RE UEST FOR ADDITIONAL INFORMATION REACTOR PROTECTION SYSTEM SETPOINTS (1)
Has FPL verified that the bases document used by Westinghouse to determine the instrument allowances (uncertainties) is correct and applicable to Turkey Point as configured?
In addition, please provide the following:
a.
What are the inputs for the bases document?
b.
Were there any "generic" allowance (uncertainty) values used by Westinghouse when plant-specific information was not available or not based on Turkey Point specifications and procedures?
If so, what confidence level does FPL have that these values reflect (or bound) the as-configured condition of the plant?
c.
Are the allowance (uncertainty) values used applicable and conservative with respect to the as-configured plant' (2)
Recently approved Amendments 135 and 140 approved specific values in the OTbT and OPbT equations (table notes 1,3).
The amendment under current review proposes some of those values in a different form, i.e, from note 1:
proposed p~
R 2235 I
from note 3:
prop'osed K4 5 1.09 K
>.02/
F t(Tau)7 R 10 secs.
Are these new proposed values conservative (in the conservative direction) with respect to the existing TS (Amendments 135 and 140)?
