Dear Dr. Murley:

Technical Specification 3.12.1 requires certain capabilities for Environmental Sample Analysis. These Lower Limits of Detection (LLD) for various radioisotopes are listed in Table 4.12.1-1. The Technical Specification also recognizes that occassionally uncontrollable circumstances may render the LLD's unachievable. In such cases, the contributing factors shall be identified and described in the Annual Radiological Environmental Operating Report.

For the samples collected in 1984 and reported in the Annual Report submitted to the NRC on April 30, 1985, the required LLD was not achieved for Ba-140 and/or La-140 on 16 required samples. PP&L recently noted that list the factors which caused the missed sensitivities. The 16 samples are it failed to listed in Attachment 1. The reason for the missed sensitivities was that the samples were not counted promptly enough at the vendor laboratory.

We have taken st:eps to assure that the analysis of the samples arriving at the laboratory will not be delayed. All analysis to date in 1985 have met the Technical Specification LLD requirement. contains revised pages for the 1984 Annual Radiological Environmental Monitoring Report. The revised copy footnotes those samples with missed LLD's and identifies the factors which caused the missed sensitivity. J If you have any questions, please contact us.
