Docket No. 50-320 Mr. Robert Flick 427 E. Elizabeth Street New Castle, PA 16105
Dear Mr. Flick:
Your letter to Mr. William J. Dircks regarding the femation of krypton and entry into the reactor building and other contaminated areas in the plant has been referred to me for resconse.
Regarding your statements about reversing the process (i.e., fission) which leads to the formation of krypton and other fission products, at present, there does not exist the technical capability for reversing the process to recombine the high atomic number fission products of the uranium-235 fission event. The practical means for processing noble gases such as krypton are discussed in detail in NUREG-0662, " Final Environmental Assessment for De-contamination of the Three Mile Island Unit 2 Reactor Building Atmosphere",
which was forwarded to you in previous correspondence.
Regarding entry into the reactor building, three such entries have been made since the completion of the reactor building purge. Prior to each entry, the reactor building is purged of the residual krypton in the building atmos-phere to ensure a safe working environment for the entry team members. Small amounts of krypton accumulate in the building atmosphere from the source of krypten dissolved in the 600,000 gallons of waste water in the reactor building sump.
Regarding your question about other contaminated areas of the plant, the licensee is continuing the effort of decontaminating the affected areas of the auxiliary and fuel handling buildings. To date, approximately 65% of the contaminated areas in those buildings have been decontaminated and the majority of the remaining work is in cubicles housing contaminated equipment.
I trust that this infomation adequately responds to your concerns.
Sincerely, cc:: :. n :;y
