SAN ON0FRE UNIT 1 STEAM GENERATOR TUBE LICENSING ACTIONS Date M 07/18/74 Letter transmitting Regulatory Guide 1.83 and requesting proposed change to the Technical Specifications (TS).

04/01/77 Amendment No. 25 to license requires steam generator to be reinspected within 12 months '

from the date of the amendment.

10/06/77 Order r quiring that the licensee submit information needed to ' confirm the rate of growth of steam generator tube degradation in the vicinity of the old anti-vibration bars.

12/20/77 Amendment No. 29 pertains to eddy current test on steam. generator tube degradation and requires steam generator inspections.

1 03/24/78 Amendment No. 32 clarifies when the twelve-month s/ inspections of steam generators must be made, which is in reference.to Amendment No. 25.

04/20/78 Amendment No. 34 acknowledges that the results of the steam generator denting inspection program satisfy license requirements and, therefore, approved resumption of power operation, in reference to Amendment Nos. 25 and 32.

10/31/82 Amendment No. 37 acknowledges that inspection results indicate that the steam generator tube denting and support plate cracking have been connected.

We, therefore, found performance of subsequent steam generator inspections in accordance with ISI, TS 4.16 acceptable. .

06/08/81 Amendment No. 55 approves steam generator tube sleeving.

    • This column contains some repetitive defects in subsequent inspections. Dented tubes which will not pass a size 0.700 inch probe are included in this column.

However, by definition they are not defectin tubes. Sey are simply tubes of concern. A degraded tube is one which has g nater than 20% thinning of the wall from its original dimensions. A defective tube has > 40% of the, tube wall thickness removed. A dented tube which will not pass a 07610 inch probe Wil generally be plugged.

(b) Denting is described as extensive, moderate, or minor as follows:

extensive denting - (a) presence of tube denting that is widespread throughout whole steam generator in which the average total reduction in tube diameter equals to or exceeds twice the tute wall thickness; (b) measurable support plate in-plane deformations, such as hour 11assing of flow slots in Westinghouse plants; (c) damage has caused leaking from dents.  ;

moderate denting - (a) presence of tube denting that is widespread throughout whole steam generator in 'which the average total reduction in tube diameter exceeds 20% of the tube wall thickness; (b) no measurable support plate in-plane deformation; (c) damage has g caused leaking l

from dents.

l minor denting - (a) presence of tube denting is spotty to widespread,*but the average total reduction in tube diameter is less than 20% of the

- tube wall thickness; (b) no visible support plate deformation; (c) damage has n$tt caused leaking from dents.
