In cecordance with Specifications 6.6.C.1 and 6.9.C of the Technical Sp:cifications, Dresden' Station has changed from using the station liquid r;dwaste processing equipment to using CNSI's equipment as the normal means fcr dewatering and colidifying liquid radwaste as described in CNSI's Topical R:pretl which was approved.by the NRC on April 11, 1983.

Dresden Station has rivided its Process Control Program to reflect the fact that vendor carvices have become the primary means of processing liquid rad waste rather thin the permanently installed Station system (Stock System).

This change was On-Site Reviewed in accordance with Station procedures.

Use of CNSI's NRC cppesved process control program and equipment will continue to assure that w cto processing at Dresden Station is performed in accordance with applicable critsela and requirements. This change was implemented as a more cost cffective manner of processing waste as well as reducing radiation exposure to ctition personnel. Additionally, the revised PCP requires that the topical r:ptet for the vendor services must be submitted to the NRC and the colidification/ stabilization media must be approved by the licensed burial sites prior to use at Dresden. The PCP (Revision 1, February,1988) is cttached.
