| | l On July 9,1981, your office "as provided with an interim report of a potential 10CFR50.55(e) concerning pipe hanger stiff clamps. Addi-tional evaluation was required to resolve design questions encountered during the course'of the e.gineering study. - |
| | The architect / engineer's intended final report, which addresses major points of the subject and includes the program to be implemented for final resolution of the deficiencies identified, was submitted for Supply System review on September 15, 1981. The Supply System has re-viewed the report; however, prior to forwarding it to your office, we have requested the architect / engineer and stiff clamp supplier to per-form additional technical cvaluations./ It is anticipated that one month will be required to obtain and review this evaluation. |
| | We will provide the final report on this hubject by November 4, 1981. |
