Dear Sirs:
Three Mile Island Nuclear Station, Unit 2 (TMI-2)
Operating License No. DPR-73 Docket No. 50-320 Deep-Bed Filter as Canister Dewatering Filter This is to inform you of GPU Nuclear's plan to test the effectiveness of a deep-bed filter as the filter in the Defueling Canister Dewatering System (DS-F-1).
Previously, filter canisters have been used in this mode.
The use of a filter canister as DS-F-1 has not been efficient. While filtrar. ion has been acceptable, throughput has been extremely low. As a result, the use of an alternate filter is necessitated. GPU Nuclear is proposing to use a modified knockout canister with diatomaceous earth (DE) and sand as the filter media for this purpose. The knockout canisters to be used will be those modified as " deep-bed" filters previously addressed in GPU Nuclear letter 4410-86-L-0173 dated September 26, 1986. The use of DE has previously been evaluated in GPU Nuclear letters 4410-86-L-0104 dated June 30, 1986, and 4410-86-L-0203 dated December 1,1986, 8702260369 870220 PDR ADOCK 05000320 P

Document Control Desk February 20, 1987 4410-87-L-0024 The System Description for the Dewatering System will be updated if the
" deep-bed" filters prove effective as dewatering system filters.
