Liquid effluents from the TMI site released to the Susquehanna River after i processing, were made within the regulatory limits and in accordance with NRC ' requirements and City of Lancaster Agreement dated February 27, 1980. l During the period August 21, 1981 through August 27, 1981, the effluents contained no detectable radioactivity at the discharge point although - individual efflue'n't sources which originated within Unit 2 contained l minute amounts of radioactivity. Calculations indicate that less 1 ten thousandths (0.0001) of a curie of tritium was discharged. d, I 9

1 2. En_vironmental Protection Agency (EPA) Environmental Data. Results from EPA monitoring of the environnent around the TMI site were as follcws: 3 The EPA measured V,r-85 concentrations (pCf /m ) at several - ' +- - environmental monitoring stations and reported the following ^ resul ts : Location n July 31 - August 14, 1981 -- _ (pCi/m ) 4 Gol dsboro 32 Observation Center 27 Middletown 28 4 Yorkhaven 27 All of the above levels of Kr-85 are considered to be background level s. No radiation cbove normally occurring background levels was - detected in any of the samples collected from the EPA's air and gamma rate networks during the period from August 19, 1981, through August 27, 1981. 3. NRC Environmental Data. Results from NRC monitoring of the environment around the TMI site were 'as follows: The following are the NRC air sample analytical results for the onsite continuous air sampler: I-1 31 ' Cs-137 Sample Period (uCi/cc) (uCi/cc) j ' ^ I HP-282 August 19, 1901 - August 26, 1981 <9.2 E-14 <9.2 E-14 U j a 4. Licensee Radioactive Material and Radwaste Shipments. 3 On Monday, August 24,1981, a 40 ml Unit 2 reactor coolant 2 sample was sent to Babcock and Wilcox:(B&W), Lynchburg, Virginia. On Monday, August 24,1981, one 6' x 6' EPICOR I dewatered resin liner (liner P-7) from 'Jnit 1 was shipped to Chem-Nuclear Systems, Incorporated, Barnwell, South Carolina. On Tuesday, August 25, 1981, 107 drums c0ntaining Unit 1 and 4 ) Unit 2 contaminated laundry were shipped to Tri-State Industrial Laundries, Utica, New York.- i s + ,f

Y On Thursday, August 27, 1981, 70 drums containing Ursit 1 and Unit 2 contaminated laundry were shipped to Tri-State industrial' Laundries, Utica, New York. 7; ..s On Friday, August 28, 1981, 41 drums and 7 metal boxes of Unit ~ ~ ~ ~ ^^- ~ - - - 1 LSA compacted a'nd noncompacted waste were shipped to Chem-Nuclear Systems, Incorporated, Barnwell, South Carolina. On Friday, August 28,1981, one 6' x 6' EPICOR I dewatered ~ ^ resin liner (liner P-5) from Unit 1 was shipped to Chem-Nuclear Systems, Incorporated Barnwell, South Carolina. 5 TMI Occupational Exposure. - Licensee records Lindicate that the cumulative Unit 2 occupational 7 radiation exposure (bj thermoluminescent and self-reader dosimef Jes) ' for 1981 (as of July 31,1981) is 84 man-rem. The station total (Unit 1 and Unit 2) for 1981, which represents thut of 5,932 monitored individuals, is 180 man-rem (as of July 31, 1 981). Major Activities , Submerged Demineralizer Systan. Start r, testing is in prngress following ai outage to incorporate minor system modifications. Of, 27 procedures to be updated,19 have been received by the site THI:PO. Of there,12.have been approved, 3 have been returned to i the licen ee to resolve (eyar:Ots, and 4 are undergoing review. A r trial period of processing intermediate water is expected to begin during the week of August 30, 1981, and staging hnd processing.of a small be+.ch (approximately 15,000. gallons) of reactor building sump water is expected to begin shortly thereafter. 4 2. Reactor Building Entry. Five teats, a total of eleven people, entered the Unit 2 reactor building during entry number fifteen on - 4 August 27, 1981. The first team entered the building at approximately 9:30 a.m. The last team exited the building at 4:30 p.m. The following tasks were successfully completed. Measurements using a portable gamma spectrometer. Closed circuit television maintenance. Air cooler inspection and survey. RB tool remeval, clean-up, and inspection. ) The sixteenth reactor building containment entry in order to continue. accident related data aquisition, is scheduled for September 24,1981.: 1 ^ l'1 is t ~
3. U. S. Departmen of Energy __to take EPICOR II Wastes for Research and Development In July, the NRC and Department of Energy (6ET) signed a Memorandum of Understanding to help ensure that TMI does not become a long-term waste disposal facility (see Weekly m Status Report, August 3,1981).. Discussions between DOE, NRC and, GPU have led to the DOE decision to take, for research and' development l.. ' : r;. C, (R&D) purposes, the 49 highly radioactive EPICOR II frefilter liners c. - e: rt ~ . that are currently stored at TMI. The liners. contain approximately tsy: - ~ 50,000 curies of radioactive cesium and strontium that were removed ~7 ~" by the EPICOR II system from 500,000 gallons of radioactiva water from the Unit 2 auxiliary bui1~ ding. DOE's R&D program will evaluate the different materials in the liners to answer various generic questions regarding treatment and disposition of ion exchange media including:
- 1) What is the appropriate method of disposal for such resins',
~ considering both economics and safety of disposal? 2) How much radioactivity is being retained in the organic portion of the liner' versus the inorganic portion? 3) What changes occur in physical. state of these media with time? 4) What is the effect of dewatering? and 5) What is the extent of gas buildup in the various liners and how much is due to radiolytic decomposition of water versus breakdown of the organic resin? GPU Nuclear will reimburse DOE for shipping and ultimate disposal costs. It is expected that the first of these liners will be shipped s in early 1982. l 4 w 9 k al ~ u 4
2 I ~ i -s_ Past Meetings I' l. On Friday,~ August 28, 1981, Lake Barret met wit' h the Middletown mothers to discuss the Unit I administrative hearing process and. the Unit 2 cleanup. They expressed their opinion that Unit.1 should not start up prior to the completion of Unit 2 cleanup. Future Meetings; l. On Tuesday, September 1,1981, the Advisory Panel for the Decon-tamination of TMI Unit 2, will meet from 7:00 p.m. to 10:00 p.m. at the lloliday Inn, 23 South Second Street, Harrisburg, to discuss current activities at TMI. This meeting will be open for oublic; observation. 2. On Wednesday, September 2,1981, Lake Barrett will address the York Rotary Club to give an update on the decontamination and cleanup efforts at TMI. 3. On Thursday, September 3,1981, Lake Barrett will address the Middletown Rotary Club to give an update on the decontamination and cleanup efforts at TMI. i 'J e 4 6 / ~. l f 't - s: 7 ' .y g'}}
