Subject:

Response to Notice of Violation on Containment High Range Radiation Monitor Gentlemen:

In Reference (d) you transmitted to Maine Yankee a Notice of Violation concerning the placement of our containment high range radiation monitors.

This letter is in response to that Notice of Violation. Below is stated the violation from Appendix A of your letter and our response:

In an " Order Confirming Licensee Commitments on Post-TMI Related Issues", dated March 14, 1983, the Nuclear Regulatory Commission ordered the licensee to implement and maintain specific items, as described in the attachments to the Order, in the manner described in the licensee's submittals noted in Section III of the Order, and no later than the dates in the attachments to the Order.

Attachment 1 to the Order indicated that the actions pertaining to the installation of containment high range radiation monitors were completed (pursuant to the criteria specified in NUREG-0737, Item II.F.1) on January 1,1982.

Contrary to the above, as of October 10, 1984 the licensee's installation of high range radiation monitoring channels in the containment was insufficient in that the detector assemblies were not widely separated, did not view a large fraction of the containment volume, or view widely separated spaces within the containment.

This is a Severity Level IV violation, gg/ 0 8509090078 850026 qG 1 6315L-FWS PDR ADOCK O y9 .
