- M i 09 1979 L.fY 23 Analysis of Three-Mile Island Charcoal Filter Samples suaa.cT:
To: John M. Deutch, Acting Assistant Secretary for Energy Technology NRC recently requested the assistance of Dr. V. Dietz, Na a x"3J2 n' Laboratory, in analyzing samples of charcoal filter media from Three-Mile Island. This 1ddt~ed'irioFt'," short-term work relates to work Dr. Dir.tz has done under an ETW/P supported contract.
The necessary arrangements were made and the analyses are underway (no impact on ETW/P program). We will receive a copy of the NRL report prepared for NRC.
The attached memorandum to me from Goetz Oertel provides additional information.
We are notifying you of this because of your interest in DOE support efforts related to Three-Mile Island.

SUBJECT:
ETW/NRC Cooperation on Three-Mile Island Iodine Release Measurements To: Sheldon Meyers, Program Director Office of Nuclear Waste Management Informal discussions with NRC personnel at Three-Mile Island (TMI) have determined that much of the iodine leakage during and af ter the accident was due to faulty charcoal filter media (KIx impregnated activated char-coal). It passes the current NRC efficiency test satisfactorl.ly, but the organic iodine bleeds off slowly after th. initial capture, a phenom-enon which the test does not measure.
This phenomenon was revcaled in an ETR/P-supported paper presented by Dr. V. Deitz (NRL) at the August 1978 "15th DOE Nuclear Air Cleaning Conference." The responsible NRC staff participated in this Conference.
NRC recently asked us to permit Dr. Deitz to carry out iodine " bleed off" tests on samples of the TMI charcoal. Results to date confirm previous
- results, i.e., they do bleed off as much as 70-80% of the organic iodine initially absorbed.
Backup beds impregnated with TEDA (a proprietary amine compound patented in England), now in place at TMI, are retaining the iodine satisfactorily.
It is our understanding that most power reactors now in service also utilize the KIx charcoal.
DOE has used the TEDA treated media at SR for several years. About three years ago our legal department received a request from Sutteliffe-Speakman (a UK charcoal company) indicating they were the sole licensee of Harwell and requesting an exorbitant license fee. At that time, we embarked on a program -- also with Dr. Deitz -- to find a competitive product. Another amine compound HMIA proved adequate and it cost less, as well. This new product (a DOE patent is in place) may now find wide-scale use.
