Dear Mr. Carns:
SUBJECT:
ARKANSAS NUCLEAR ONE, UNIT 1 FIFTEENTH YEAR REACTOR BUILDING TENDON SURVEILLANCE REPORT DATED JULY 20,1988(TACNO.69073) g The NRC staff has reviewed the subject report and the supplemental information provided by letter dated September 13, 1989, regarding the fifteenth year tendon l
L surveillance. The staff concurs with Arkansas Power and Light Connany's C
(AP&L's) conclusion that no abnormal degradation has occurred in tie reactor building post-tensioning system. Our detailed safety evaluation is enclosed, i
The staff suggests, however, that to further ensure the material condition and
' integrity of the post-tensioning system, AP&L should consider acceptance i
r criteria for free water content and grease void, and' establish actions _to be
'j taken when the criteria are not inet. An example of an action would be to perform an internal engineering evaluation of the containment and verify that containment integrity is maintained within 30 days of discovery that the acceptance criteria are not met.
Sincerely,
/s/
