, 't Proposed Change E '

The proposed change eliminates paragraph' 4.0.2.b which defines the maximum 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.

t 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 -

forced shutdown or performing surveillances during unsuitable plant b(. 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.
