Docket No. 50-277 Paech Botton Ur.its 2 and 3 Technical Cpectrication Referenr.e:
3.7.C.d Report No. 2-80-9/IP Occwrence Date:
May 2,1990 Identification of Occurrence:
Tallure to maintain secondary contairment integrity during survenent of irradiated fuel within the spend risol pool.
Conditions Prior to Occurrence:
Unit 2 shutdown: all fuel renoced fYocs the reactor.
Apparent Cause of Occurrence:
Failure to adequately specify required conditions under which modification to secondary conteirunent boundary could be perfor: sed.
Analysis of Occurrence:
On %e riorning of May 2,1954), an irradiated fuel bundle was relocated in the spent ruel pool for the purpose of lead test assembly inspection.
The accondary contaireient leak rate test perfoM on 5/2/eo indicated tnat the contairrsent boundary passed flow in excess or that listed in the i
Technical Spectrication surveillances requirement paragraph 4.C.7.
This secondary contatrosent test was performed to verify that secondary contalement naa been re-established following the mval or an FRR ptaus notar- (Poe the Peactor Buildirug on May T.
1960.
An investtgation revealed tnat tne probable cause fbr failwe of the esecondary contairment leek rate test was the removal of steam and feedemater a
line Reactor Building penetration boots on May 1, f960. These boots were
(
removed so that they may be replaced with an improved caterial : sore suited 9g!
to the temperature and radiation envLrorrient that exist.s at fnall power.
t DTD D ]1 k f
n u
e a
. CorrectEve Actton:
411 fuel movement within the Reactor susadina km* suspended on 5/2/40 until secondary containment lategrity can be reverified. The boots will be replaced with improved material as soon as pp.=31ble.
A procedure which delineates the conditions tander which ressavat of these boot seats is permitted will be prepared so thin type of error will he prevented in the future.
AdditIoneI cecrectiwe metion may be regskred after evaluation of this occurrence is completed.
