Office of Inspection and Enfomement RII: JP0 Region II - Suite 3100 50-321/50-366 101 Marietta Street, NW I&E Bulletin Atlanta, Georgia 30303 81-03 ATTENTION: Mr. James P. O'Reilly GENTLEMEN:
Georgia Pcwer Company hereby submits the following information as a supplement to our letter dated May 22, 1981 which responded to I&E Bulletin 81-03, " Flow Blockage of Cooling Water to Safety System Components By Corbicula Sp. (Asiatic Clam) and Mytilus Sp. (Mussel)":
Our May 22, 1981 response indicated that the Rm heat exchangers and some service water piping were awaiting examination and that NRC would be notified if any clams were detected.
Unit 1 Rm Heat Exchanger "A"
was inspected and in the small pile of debris found, twenty percent (2(R) was identified as asiatic clam shell fragments which varied from 1/4 to 1 inch in length.
This does not present any significant problem and the debris was not consioered unusual.
Five pement (5%) of the debris found during the inspection of the Unit 1 Rm Heat Exchanger "B" was also identified as asiatic clam shell fragments which varied from 1/4 to 1/2 inch in length.
Unit 2 Rm Heat Exchanger "A" was inspected and one percent (1%) of the debris found was identified as asiatic clam shell fragments which varied in length from 1/4 to 1/2 inch in length.
Inspection of the Unit 2 Rm Heat Exchanger "B" did not reveal any asiatic clam shell fragments.
Please be advised that there was not any tube blockage, any live clams, or whole clam shells discovered during the inspections of the heat exchangers.
All debris found in the four heat exchangers totalled 1 to 3 pounds in weight and consisted primarily of steel fragments, rocks, and gravel.
The service water piping was also inspected and no evidence of clams or clam shells was found.

O GeorgiaPower d United States Nuclear Regulatory Comission Office of Inspection and Enforcement Region II - Suite 3100 Page Two June 15, 1982 In summary, Plant Hatch does not have a clam infestation problem.
Continued chlorination of our service water along with regular maintenance and inspection should preclude any clam problems in the future.
The Mytilus Sp. (Mussel) was not addressed in this supplement as it is a salt water species and is not present in the Altamaha River in the Plant Hatch vicinity.
If you have any questions in this regard, please contact my office.
J. T. Beckham, Jr. states that he is Vice President of Georgia Power Company and is authorized to execute this oath on behalf of Georgia Power Company, and that to the best of his knowledge and belief the facts set forth in this letter are true.
