Dear Mr. Rouse:

Please refer to our request for an amendment to Teense SNM -1174, Docket 70-1193 requesting an authorization to use an ion exchange column for removing Plutonium contamination from waste cleanup solutions.
As you know, there are two ion exchange glove boxes in the Plutonium plant and it was our intention to include both in this amendment.
The second box was inadvertently omitted.
Would you please revise the attachment to our letter of January 11 to read:
" Paragraph F The operation of the ion exchange columns Iccated in glove box 31 A, Room 127 and glove box 40 in Room B01..."
Your letter of March 18 on this subject asked for some additional information which is provided below.
The ion exchange systems were a part of the processing sequence during tha oporntton of the Plutealum feel plant. Tbc JX syst w are made up of 3 columns located in glove box 31A and two columns located in box 40.
Each system will consist of a feed tank, either a mop water container or a " pencil" tank in Room 127, to which a soda ash solution will be added and the resulting mixture pumped through an in-line filter fu the glove box and subsequently through the ion exchange columns with the effluent solution returning to an empty " pencil" tank.
The " pencil" tanks are comprised of an array of eighr 5-inch tanks (schedule 80, steel).
The rece i ving t.mk wili 1, samp! M i or piutoniea and re teaced only If IL o
contains 0.1 Mpc for unrestricted ielease or less.
In the event this level is exceeded, the solution ulll be again passed through an ion exchange column.
Excessive plutonium concent ration would only occur in case the column was breaking through or the rate of flow was excessive.
p.g 1.,
In no event will the effluent from the ion exchange be discharged to 20429 Dl6 kh
e X
L. C.' Rouse, Chief March 24, 1982 Page 2-4 the lagoon in excess of 0.1 MPC for unrestricted release.
The ion exchanc.e column and tanks are 5" diameter and geometrically safe.
Specific nuclear safety analysis have been made in.the past for these nystems. Based-on previous process and scrap operations, the tanks are spaced and snounted according to proven nuclear safety practices.
Your prompt response would be appreciated.
