Dear Hr..Standerfer:
h Subjecti Recovery Operations Plan Change Request No. 41 x.
MR By letter dated May 20, 1987 you submitted Recovery Operations Plan Change
?!c Request-(ROPCR) No. 41. The R0PCR proposed modifying Sections 4.9.12.1.e and C
4.9.12.2.e of the Recovery Operations Plan (ROP) to allow use of local y 'J differential pressure indicators as well as those in the control room for r
verifying operability of the Auxiliary Building Air Cleanup Exhaust System and X$
the Fuel Handling. Building Air Cleanup Exhaust System. The current R0P only allows use of the contro? room instruments to verify system operability.
I We have completed our review of your submittal and have determined that the alternate instrumentation described in your evaluation is acceptable for
.J s verifying the Fuel Handling Building and Auxiliary Building Air Cleanup
,i
. Exhaust Sy:;tems' operability. Allowing use of the alternate instrumentation does not relax currently imposed surveillance requirements since the alternate instruments perform the same. function as the control room instruments and will G
be monitored on the same required minimum time interval.
The use of alternate
@it instrumentation does not increase the probability or consequences of i
.previously analyzed accidents, does not create the potential for additional J
.r accidents not previously analyzed, nor does '+, reduce margins of safety.
j j
g",
We therefore approve your request for modification of R0P sections 4.9.12.1.e j
and 4.9.12.2.e.
The revised Recovery Operations Plan pages are enclosed. Our i
?
approval of your R0PCR No. 41 is designated as change approval No. 38. These i
m changes are effective as of the date of this letter.
