" Reactor Coolant System Criticality Report" dated March 15, 1985 Reference (a) submitted the Safety Evaluation Report (SER) for the THI-2 i
Temporary Reactor Vessel Water Filtration System (TRVWFS) to the NRC staff for i
approval. The NRC staff safety evaluation and approval were docuwnted.in reference (b). Reference (c) forwarded a revised SER for the system for review and approval.
4 We have reviewed the revised SER and we approve continued operations of the i
system with certain restrictions and administrative controls as discussed below. Following further discussions between our staffs, information transfer j
regarding fission product transport assumptions and dose conversion factors and NRC staff review of this area we may remove these restrictions.
i The only sources of water passing through or contained in the TRVWFS including the waste storage drum are horated to greater than' 4350 ppm B.
These sources, t
the reactor coolant system (RCS) and borated water storage tank BWST, are t
maintained at a nominal 5000 ppm B with a technical specification minimum of 1

References (d) and (c) provide a bounding criticality safety evaluation and f1RC approval of a configuration nuch more restrictive than any attainable by the TRVWFS, provided that the greater than 4350 ppm B condition is met.
The following restrictions apply to the continued operation of the TRVUFS:
(1) Only sources of water containing 2: 4350 ppa B may be processed through or stored in the TRVHFS.
(2) The waste storage drua must be sampled and analyzed for fissile material content prior to solidification or transfer to another container or systen.
System aparating procedures and procedures delineating waste storage drum sampling and analysis are subject to approval per Technical Specification 6.8.2.
