Eu:r.ary :
Representatives from !; MSS visited TMI on June 5,1973 to discuss with i-!RR t epreser tatives, Metrcpolitan Edison's plar.s for processing the T111-2 facility wastes.
Specific emphasis was placed on vaste dispsal and transportation.
Tne fiRR representatives noted that.their on-site operation at TMI involved procedure revicis with their attention directed to health, safety and protection of the environment.
These reviews are the saae as what uould normally be7 ene 7 d -) by ETSG in Bethesda.. Ji! Seven (7) liners of filter r:edium and resin from credominantly Unit 1 processing and 4Du steel 65 gallon drums of compacted lo.!-level waste.was prepared for shipmnt. This was te was 7.9080'70 stated to be typical of any other utility waste and would be i~ shipped accordingly. c=* ..Al '..shipnants..le ving..the-si to a re..i n spe c te -.by ILE..for ..-...

l " ;i iW s t u (p. s. ,c _ c Ui th res,w.t to Tl11-2 waste, planning is proceeding in three i separate steps: a) decontamination of approximately 200,000 l gallons of contaminated water frgthe auxiliary building (the limiting radionuclide); which has less than 40 pCi/ml Cs b) decontamination of approximately 800,003 gallons of water in the primary containment which is contaminated to a higher but j not well characterized level and c) cmc removal Only the I first step is well defined at this time. !'etropolitan Edison is seeking contractors for processing equipment for handling i the uaste in tSe containrnant. BechtEl Corp. has been selected i. to study cora removal. j l With regard to the planned first step to clean-up the 200,000 { ~ gallons of Ucter from the auxiliary building, a system (Epicor-II) has been desigr,ed and installed in a facility originally designed for chemical cleaning of the steam gen, tors. This system is now being checked out but will not be nude operational until completion of an environmental assessment and delivery of a shield bell for handling of the processing units when they are depleted. ~ The shield bell will be delivered in approxirately five weeks. The system for processing the contaminated water involves three i processing units in series. The processing unit: are: 75 l) an ini tial prefilter using silver impregnated charcoal',
- 2) a demineralizer; and 3) a polisher.
The prefilter is i 1 4' diameter by 4' high carbon steel cylinder. The dem r 'lizer l is also 4' by 4'. The polisher is 6' diameter by 6' hi, Thcse t units will be operated until activity on contact reaches 2,bJO r/h, t 400 r/h and from 20 to 30 r/h, respectively, or until the m.edium lor s its capability. These units when depleted and when dewatered I wili be rer.oved and replaced with identical new units. The units l will be stored temporarily on site in an interim carthern embankment and subsequently in an engir,eered storage facility. All cnits are t. pla ned to be shipped to Richland for burial. Present plans call fo. the 4' by 4' units to be shipped in accident resistant packaging (Type B) and the 6' by 6' units to be shipped as LSA naterial~ in Type A packaging. Type B package designs are not available for shipment of the Type B wastes. The fiRR representatives requested prompt fiMSS action on any requests for iiRC certification for, ) Type B packaging for TMI wastes. Jli 324 t It was i.oted that Metropolitan Edison's plans for processing the waste are consistent with present practice follo. led in older plants but are not consistent with the Effluent Treatment Systems Branch (i RR) Technical Position ETSB,ll-3 uhich has resulted in neu U.'R plants installing capability to place all wastes in a solid irrobile L__. form prior to shicment of f-site.
