Dear Mr. Farrar:
This letter acknowledges receipt of your response dated April 19, 1994, to NRC Bulletin 93-02, Supplement 1 (Bulletin). The Bulletin was issued February 18, 1994, to all Boiling Water Reactor (BWR) licensees for action and to all Pressurized Water Reactor (PWR) licensees for information.
The purpose of the Bulletin was to inform BWR and PWR licensees about the vulnerability of ECCS suction strainers in BWRs and containment sumps in PWRs to clogging during the recirculation phase of a loss-of-coolant accident (LOCA), to request that BWR licensees take the appropriate actions to ensure reliability of the ECCS in view of the information discussed in this Bulletin Supplement, and to require that BWR licensees report to the NRC on the requested actions taken.
Your response adequately addressed the actions you have taken to assure the operability of ECCS recirculation. Please retain any records of your actions in response to this Bulletin, as subsequent inspection activities may be conducted in regard to this issue.
Should you have any questions, please contact me at (301) 504-3016 or the lead Project Manager for this. issue, M
.. David Lynch, at (301) 504-30~3.
