(66) The halon system will not maintain the required design concen-tration within room 2235 due to leakage through fire dampers. The t
fire dampers automatically close upon operation of the halon
-
system but apparently do not close tightly.
The fire damper
!
,
manufacturer has recommended that the existing spring closing device be replaced with a different type spring.
This change.
should correct the problem. The licensee advised that this change t
will be made and system retested prior to fuel load. This item is identified as Inspector Followup Item 364/81-08-05), inadequate

(117) An inspection was made of all fire damper installations by the
contractor's QC group.
This inspection was audited by the l
,
licensee's construction QA group.

(119) The licensee is currently re-evaluating 18 doors installed
j throughout Unit 2 to determine if they meet the commitments to the i
NRC and are satisfactory or need to be changed.
These doors
,
include a total gof 13 security and water tight doors and 5 doors
.
provided with a removable transus. The existing doors provide a
!
!
l fire stop in the fire barriers but the exact fire resistance
!
rating of these doors is not known.
This ' item is identified as
!
Inspector Followup Item (364/81-08-04), licensee's evaluation of l
unlisted or approved fire doors, and will be inspected during a
subsequent NRC inspection.
j
.
l (122) The service water pumps are provided with an automatic closed head j
water spray system. This system will probably be of slow response
in the event of a motor or pump fire since the sprinkler heads are j
'
located an excessive distance below the ceiling or roof of the
building and are not provided with heat collectors as required by l
NFPA-13. This problem was identified to the licensee in IE Report i
!
Nos. 50-348/80-03 and 50-364/80-03 and to NRP by NRC/IE interof-fice memorandum.
NRR's memorandum response af August 18, 1980, i
from V. Benarcya to S. E. Bryan, IE:HQ advised that the existing i
'
system was satisfactory and was recommended during NRR's fire j
protection site visit.
Since this item is acceptable to NRR no i
further action will be taken by NRC Region II to correct this
discrepancy.
