ATTENTION: James G. Keppler Director, Region lli Office of Inspection and Enforcement

Dear Mr. Keppler:

On March 26,1991, Connex Pipe Systems, Inc. discovered that we had fumished to Tennessee Valley Authority (TVA), Browns Ferry Nuclear Plant, twelve (12 each) 1 1/2" -

3000# Socket Weld Unions, ASTM B247 Alloy 6061 T6 on their order number 90NJS-825570 and three (3 each) 3"- 150# Pipe Flanges, ASTM B62 Cast Brass on their order 91NJA 82667C which fail to comply with their purchase order requirements.

Their Purchase Order required the material to be supplied following an ANSI N45.2 Cuality P ugram. The material was actually supplied following a ecmmercial program.

Connex cannot verity the quality of the items; therefore, our Manager of Quality Assurance is working with Mr. Robert Bradley of TVA to have all of the material on these orders retumed to Connex. We hope to have the material returned by April 5,1991.

Please contact us, should additional information be required.

Sincerely, CONNEX PIPE SYSTEMS, INC.
