Dear Mr. Haynes:

SIGNIFICANT CONSTRUCTION DEFICIENCY DAMAGED BELLOWS ASSEMBLY NO. 2 UNIT, 50-355 HOPE CREEK GENERATING STATION On November 4, 1981, a telephone report was made to Region I representative, Mr. E. Greenman, advising him of damage to a bellows in the Unit #2 primary containment. The following interim report is submitted in accordance with 10CFR50.55e.

Description of the Deficiency The Hope Creek containment is a " Mark I" drywell and torus with eight (8) vent lines connecting the drywell to the torus. Each vent line contains two expansion bellows as-semblies. During testing of the bellows by the installation contractor, Pittsburgh-Des Moines Steel Company (PDM), a hole was detected through both plies of the outer bellows in ventline 8A.

Safety Implications The perforation of both plies of a ventline bellows, if left uncorrected, would result in a breach of containment during accident conditions.

Corrective Action Our Architect Engineer, Bechtel Power Corporation, has in-structed PDM to perform the following:

1. Inspect all other Unit #2 ventline bellows assemblies for similar damage.

2. Repair or replace the damaged bellows.

3. Determine the cause of the perforation and actions nec-essary to prevent recurrence.

We anticipate completion of the inspection and investigation (Items 1 and 3 above) in early January, 1982. We will re-port the results to you at that time.

Very truly yours,
