ENCLOSURE REQUEST FOR INFORMATION SEP TOPIC IV-2 General Design Criterion 25 requires that the reactor protection system be designed to assure that specified acceptable fuel damage limiks are not exceeded in the event of any single failure of the reactivity control systems, such as accidential rod withdrawals.
1.
Describe the single failures within systems used for reactivity control which can:
a) Cause an inadvertent reactivity insertion.
b) Cause a single or combination of rods to be positioned in other than the design sequence.
For PWRs this should include consideration of single rod withdrawal / insertions which can result from a single equipment component failure.
7 2.
Delineate those design features which limit reactivity insertion rates and rod malpositions resulting from a single failmu. Provide the appropriate circuit schematics showing these design features.
3.
Provide or reference appropriate analyses to demonstrate that specified acceptable fuel damage limits are not exceeded in the event of any of the single failures identified in Item 1 above.
4.
Identify the operating procedures, alarms, interlocks, or protection system actions which must be used in limiting the consequences following a single failure within systems used for reactivity control. ~Whem equipment actions are required, indicate whether the equipment meets the' criteria of IEEE-279.
