Dear Mr. Campbell:
We are continuing our review of your letter of October 17, 1986, concerning the compliance of the reactor coolant system leak detection systems of Arkansas Nuclear One, Unit 1, with the guidelines of Regulatory Guide 1.45 for the purpose of exemption from the pipe break criteria of GDC 4 on the basis of leak-before-break. We have determined the need for additional information which is identified in the enclosed Request for Additional Information. We request your response within 45 days from receipt of this letter.
The information requested by this letter affects fewer than 10 respondents; therefore, OMB clearance is not required under P.L.96-511.
Sincerely,
/S/
John F. Stolz, Director PWR Project Directorate #6 Division of PWR Licensing-B
