SUMMARY

OF MEETING HELD ON SEPTEMBER 11, 1996, TO DISCUSS THE TROJAN SPENT FUEL P0OL DEBRIS RECOVERY PROGRAM On September 11, 1996, the NRC held a meeting with Portland General Electric (PGE) at NRC Headquarters in Washington, DC. The meeting was open to the public. No members of the public attended. Members of the NRC and the licensee that attended the meeting are listed in the attached attendance roster (Attachment 1). A copy of the licensee's handout is also attached (Attachment 2).

The purpose of the meeting was to inform the NRC staff of the licensee's plans ,

to separate a category of material called spent fuel pool debris. This j material consists of damaged spent fuel, welding dross from previous core 1 barrel modifications, other non-fuel bearing components, and organic (plastic) l filter materials. The spent fuel pool debris is stored in specially designed

" garbage" cans at a number of locations in the spent fuel pool. The purpose i of this effort is to separate the fuel and core debris from materials that I could potentially produce gas, primarily hydrogen. The licensee plans to package this material in canisters that would be suitable for storage in an ISFSI. Material that produces gas due to any phenomenon, including radiological decomposition, would be unacceptable for storage in an ISFSI.

The licensee proposes to use a steam reformer resulting in the pyrolysis of the organic compounds. The fuel debris and filter material will be packaged in canisters and subjected to a low flow (1 to 3 cfm) high temperature (1100 degrees F) steam under approximately atmospheric pressure for a number of hours. The effluent stream is subjected to higher temperatures

(>2000 degrees F) in a proprietary quartz chemical reactor. Discharge gases will be cooled, HEPA filtered, and discharged to the plant ventilation system at ambient temperature. The canister containing the material remaining after 4 the steam reforming would be packeged in capsules and then sealed into the ISFSI canisters.

September 24, 1996 The licensee has determined that this activity has the potential for a new and different accident than any evaluated in the Defueled Safety Analysis Report.

Therefore, the licensee has concluded that the activity involves an unreviewed safety question. The licensee plans to submit a Safety Analysis Report on the spent fuel pool debris recovery program in October 1996. The licensee hopes to begin processing the fuel debris by the end of calendar year 1996.
