Proposed Change The proposed change eliminates paragraph' 4.0.2.b which defines the maximum E '
s combined interval for any. three consecutive surveillances as 3.25 times the-specified surveillance interval.
{
.6 L.
Basis:
The intent of the 3 25 limit was to preclude extending surveillance intervals-by 25 percent on a routine basis. The removal of the 3 25 limit provides 1
greater flexibility in use of the provisions for extending ' surveillance.
p Lintervals reduces the administrative burden on the licensee,- and has a l
L positive. effeok on safety.
This is a Technical Specifloation line-item
[
improvement consistent with NRC policy.

REMOVAL OF THE 3 25 SURVEILLANCE INTERVAL LIMIT I
10CFR50.92 EVALUATION j
The-Commission has provided standards in 10 CFR 50.92(c) for determining-whether a significant hazards consideration exists.
A proposed amendment to an operating license for a facility involves no significant hazards considera-j tion if operation of the facility in accordance with the proposed amendment i..
would not:. (1) involve a significant increase in the probability or conse.
.j quences of an accident previously evaluated, (2) create the possibility' of a
(,.
new or different-kind of accident from any accident previously evaluated, or (3) involve a significant reduction in a margin of safety. Carolina Power &.
Light Company has reviewed this proposed license amendment request and deter-mined that its adoption would not involve a significant hazards considera-tion.
The bases for this determination are as follows:
Proposed Change The proposed change eliminates paragraph 4.0.2.b which defines the maximum
[
combined interval-for any three consecutive surveillances as 3 25 times the
[
specified surveillance interval.
i Basis' t
The change does not involve a significant hazards consideration for the p
following reasons:
- 1. : The proposed amendment does not involve a significant increase in the probability.or consequences of an accident previously evaluated because p>
there is no physical change or alteration to the facility that could cause the probability of an accident to increase. - In addition, removal of the
'3 25. combined interval enhances safety by reducing the potential. of-a -
b(.
forced shutdown or performing surveillances during unsuitable plant conditions.
2.
.The proposed amendment does not create the ' possibility of a new or
'different kind of accident from any accident previously evaluated because the design of the ~ facility and system operating parameters are not changing. Surveillance intervals are not changing and will continue to ~be limited to the 25% extension.
. 3.
The proposed amendment does not involve a significant reduction in the margin of safety because surveillance frequencies will retain the 25%
extension limit which is an acceptable extension tolerance, as documented in Generic Letter 89-14, sufficient to ensure the reliability of equip-ment. Maintaining equipment in a reliable condition does not introduce a reduction;in any margin of. safety.
