SUBJECT:
SEVENTl! RSI CAPSULE AND SITE REC 0VERY INFORMAT 1 1 On January 25, 1990, I-attended the Seventh Radiation Sterilizers', Inc. (RSI) Capsule and Site' Recovery Meeting held in Decatur, Georgia, and chaired by John Rothrock of the Department of Energy's (DOE's) Oak Ridge Operations (OR O f fice. is the agenda for the meeting. i STATUS OF CASKS 0 BUSS Cask for Shipping Special Form (SF) Waste Encapsulation and Storage-Facility (WESF) Sources: Dick Chitwood-from DOE Headquarters-said that 00E is keeping up the pressure to get BUSS approved within 00E soon and L to get an application to NRC soon, However, based on my discussions with i-Bob Burnett and Nancy Osgood of NRC's Division of Safeguards and Transportation, HRC has not yet received an application and has no information on when an application can be expected. O GE-1500 Casks: Bill Bowen from Westinghouse Hanford Corporation (WHC), the DOE contractor responsible for shipping, visited GE recently and in a private conversation, indicated that he believes that, if an emerge,ncy exists (e.g., RSI-1500 casks fall testing again), GE will make its 2 casks available for shipping WESF sources, after it repairs one of the casks. GE either has submitted or will submit a plan to NRC regarding repair of Information in this record was deleted in accordance with the Freedom of Information Act, exemptions 0A h A*A* A fM3f G.\\ t l F01A-fd - 29 9006050026 900409 PDR FOIA-GI LBER T90--29 PDR
e. h: h [w Dr. John E. Glenn' L the defective GE-1500 cask. has discussed use of the GE-1500 casks with a high official had promised to do at the December 6, 1989, meeting with NRC and the Stat of Georgia. O GE-1500 Cask from Neutron Products, Inc. (NPI): WHC is trying to deve I a schedule for use of NPI's cask; NPI is using the cask to meet prior commitments. O RSI-1500 Casks: Allan Chin reported on the status of the repair of his casks. He explained that in December before the casks were repaired, he and/or his contractor decided that one part of the NRC-approved repair l= procedure was potentially hazardous and proposed an alternative that was i approved orally by the NRC staff. Repairs proceeded and RSI submitted the modified repair plan to NRC for formal approval, which was granted. o nine casks have been repaired and passed the required tests. All The first v set of three casks have already been used to ship 12 WESF sources to the WESF Facility in Washington State. The second set of three casks were to be loaded with 12 sources on the day before the meeting; however, heavy rains in the Atlanta area caused a postponement. The second set of casks should have been loaded within a few days of the January 25 meeting. last set of three casks was due to arrive at RSI(Decatur) on January 25 - The l and should be loaded shortly after the second set of casks are loaded. Dr. Chin expressed appreciation to the NRC staff for their timely support of RSI's applications that allowed prompt completion of the needed repairs. Bill Bowen indicated that he visited the facility at which the casks were repaired and commented on the high quality of engineering and repair work done there. 'Dr. Chin also mentioned that his shipment of the repaired casks for use by WHC was done "in good faith" because he does not have a current, valid contract with WHC. Bill Bowen acknowledged this and said that he was working with WHC procurement / contract personnel to resolve the matter.. O RSI-1500-C'ask Modifications (with Liner): with Nancy Osgood before leaving Washington.I reported that I had spoken I indicated that since the last meeting,-another issue had arisen and had been addressed and that all that remained was administrative work to issue the approval. Nancy expected that would occur in late January or early February, assuming that no new issues arose. I also mentioned that the approval (based on more than 30 days, as)would permit WESF sources to remain in the casks a revised application l contrasted to the original application that would have permitted 60 days. shipping, and receiving schedules.This aspect needs to be considered in the loadin l
a. E, 'I Ort John E. Glenn. O GE-2000 Cask: In a private conversation with Bill Bowen, he indicated that in his visit to GE he learned that GE had recently obtained certification of a new cask, GE-2000. The Certificate of Compliance could be changed fairly easily to increase the heat load so as to allow the shipment of up to 10 normal form WESF sources. This cask is very large and can be used at RSI (Decatur) without facility modification. It cannot be used at RSI (Westerville). This cask could be a backup, if problems develop with the RSI-1500 casks with liners. STATUS OF HOT CELLS AND CAPSULE TESTING Dick Chitwood reported that 00E is considering sites other than Oak Ridge National Laboratory (ORNL) for the destructive testing of Capsules 1502 and 1504. An alternative site being considered is Pacific Northwest Laboratories (PNL), which was visited recently by Sylvia Wolfe (0RO), Mr. Chitwood, and other 00E personnel. A final decision is expected by the end of January. The decision-makers include Messrs. Chitwood and Erb of the DOE staff; Mr. Bill Young, the Assistant Secretary for Nuclear Energy; and the acting Assistant Secretary for Environmental Restoration and Waste Management (currently, Leo Ouffy). One factor in the decision-making is when each facility can begin destructive testing and the other analyses (e.g., testing 1 of non-radioactive or " surrogate" salt). In a separate meeting, DOE personnel indicated that regardless of which location is selected, preliminary information on cause of failure should be available within 6-12 months. They also said that from the time the decision )_ is made with regard to. location for destructive testing, it will take 2 months l
- to bring ORNL "on line," and 3 months for PNL.
l-Since the last meeting, there has not been any work done on cause of failure 4 other thantgamma scans done at PNL and that data, given by Bill Bowen later in the meeting, is discussed below. l SHIPPING SCHEDULE AND STATUS OF WESF FACILITY Bill Bowen provid d a handout (Enclosure 2) showing the status of sources and a draft schedule as of January 15, 1990. The draft schedule indicates that shipment of special form sources from RSI(Decatur) will be completed by mid-April 1990; shipment of normal form sources from RSI(Decatur) will be completed by early August 1990; and RSI(Westerville) will be unicaded by early October 1990. This information will be needed by NRC Region III with respect to RSI's Westerville license that needs to be amended. Note that the schedule calls for sending 18 normal form sources to France. Mr. Bowen explained that these would be shipments by air using an RSI-1500 cask with liner and would benefit the project because the WESF facility would not have to process these 18 sources.
Fr 1 I Dr. John E. Glenn' 3 ; Mr. Bowen also provided an update on the status of the WESF facility at Hanford; see Enclosure 3. a few days of the January 25 meeting.The WESF hot cell should be operational within However, there are a number of WESF sources awaiting processing in that hot cell (i.e., 11 capsules in the hot cell; 12 in 3 RSI-1500 casks on the " pad" outside the building; 2 capsules in a GE-600 cask). 24 WESF sources in six RSI-1500 casks at RSI(Decatur).In addition, note should be in transit within one week (or so), These 24 sources The capabilities of the WESF facility now seem to be on the critical path. t Mr. Bowen explained that while the WESF facility had been shut down or.in. a " standby" condition, some operators were " laid off." Now WHC is under a hiring freeze and cannot hire new people. a minimum of 2 years of training / experience to work in WESF.In addition, WESF opera With the current staff (i.e., one shift), WESF can process 8 WESF sources per week. -If WHC gets additional staff to man two shifts, then WESF can process 12 sources per week. Note that the throughput does not double with the addition of a second shift because of the need to process a large volume (1 cask) of liquid waste for each 16 sources processed. In a separate meeting between 00E and NRC personnel, I urged the DOE staff to take whatever action is needed to allow WHC to hire additional staff so as . operate two shifts at WESF. i It would be most desirable to rehire or transfer back to WESF-operators who are already trained in WESF procedures, so that the 2 year training / experience requirement would not delay operations there. t TESTING 0F WESF SOURCES AT APPLIED RADIANT ENERGY COR 10 TECH This is the first meeting attended by representatives of the other two commercial facilities. respectively. Mr. Myron and Mr. Oart attended from ARECO and Iotech, WESF sources at ARECO in February 1990.As. shown in Enclosure 2, WHC plan If WHC gets its underwater television equipment in time, it plans to do intcgrity testing at ARECO over the weekend of February 3-4. The alternative dates are February 10-11. Further details were discussed ~fn a separate meeting among DOE, NRC, and Mr. Myron. of NRC Region II indicated that he would probably have an NRC inspector presented McA for the testing and that it may be the Resident Inspector at the Babcock and Wilcox Navy facility in Lynchburg. In response to a question from Mr. Myron, Sylvia Wolfe indicated that DOE would NOT provide a replacement source if one of ARECO's sources fails the integrity testing. Similar testing of the WESF sources at Iotech is tentatively scheduled for April 1990 during a time that the facility is scheduled to be " dawn." private conversation, Mr. Dart told me that WHC estimates that testing can be In a completed in 30 days, but he believes that more time will be needed. He also I 1 l
4 + b a- .Dr. John E. Glenn ) expressed concern'about the financial impact on his conipany by being shutdown for that period of time. In spite of these comments, he did not seem to be suggesting that Iotech would fail to cooperate with WHC with regard to testin RESULTS 0F GAMMA SCANNING OF WESF SOURCES As he did at the December meeting, Bill Bowen presented the.results of gamma scans of various WESF sources. See information in Enclosure 3 that includes the results of scans of three sources and a summary of data obtained on the. WESF sources subjected to gamma scanning. One of the potential program benefits is to provide a system for " periodic nondestructive surveillance of capsule condition to evaluate salt stability." In light of this, I asked if a portable gamma scanning system had been developed or was to be developed. Mr. Bowen indicated that equipment used for other projects had been "surplussed" and was available to this project. Thus, Mr. Bowen hoped that portable equipment could be available without much capital cost. He did not indicate when such a system might be available. i STATUS OF DECATUR SITE Kelly Dagenhart provided an update on this issue; see Enclosure 4. that the schedule in Enclosure 4 was prepared before seeing the draft schedule Note shown in Enclosure 3. six months can be taken off the Enclosure 4 schedule.If the Enclosure 3 s MEDIA AND LOCAL INTEREST Jim Setser from the State of Georgia reported that since the December meetin there has been increased media interest with a long article in the Atlanta Journal-Constitution newspaper;-an editorial he characterized as " ugly"; calls from at least three " interested parties" who said they were individuals but who Mr. Setser suspects represent various organizations; and reports in local papers and on radio stations. Mr. Setser repe~a'ted the concerns he has expressed in previous meetings, i.e., ~ the need to remove all the WESF sources as quickly as possible (consistent with safety requirements).and to complete work at the RSI(Decatur) facility. Mr. Setser-indicated that the State has received inquiries from staff members of three different members of Congress, the Government Accounting Office, and the offices of the Governors of Colorado and Virginia. He reminded the participants'that this is an election year and the RSI incident may become a -campaign issue. including Mr. Setser, who, after the elections, may no longer of this matter. He urged that obstacles be cleared so that the process can be speeded up and thus save money, but he emphasized that safety cannot be sacrificed for speed or economy.
l Dr. John E. Glenn OTHER MATTERS 1 This was the last meeting chaired by John Rothrock. The new chairperson will be Sylvia Wolfe. The next meeting will be in Decatur on March 1. The following meeting will be April 4 or 5 with the location to be determined later. The meeting may be in Decatur, but could be at PNL or ORNL, depending on where the destructive testing will be conducted.

emme OAK RfDOE NATIONAL LABORATORY Post omes aox aoos - r.,, - -., -,,,. - ~ = ~ nssac = \\ January 25,1990 i SITE SCHEDULE BASIS AS A BASIS FOR SITE Pt.ANNING, WE HAVE ESTIMATED THE SCHEDULE FOR RELEAS DECATUR SITE BASED ON PAST SHIPPING EXPERIENCE AND ON T TASKS This document provdes us with a site schedule for planning purposes in the days ahead, whi l Incorporates all of t1e slow downs that have been experienced. The complete shipping ex date has been used in this calculation. The shipping schedule provided at the 8/28/89 RSI 1 information Meeting by WHO is now obsolete and we will use the one provided herein. As new shipping schedules are produced by WHC we will adopt them. The attached graph gh/es a plot of WNORMAL + SP5CIAL FORM CAPSULES versus day shipment. WNORMAL is computed from.the 75 normal form capsu!es multiplied by 4/3 to a for tne tact that or.!y 3 capsules can be shippGd pst cask whereas 4 special form caps j l can be shipped. Note that there are significant second order effects not accounted for it' this l i calculation, such as the normal form overpackina complications The SPECIAL FORM CAPS weighted by unity. Note that the special feim capsulas are all to be shipped first befor the hormal form capsAs commences. To be po' tted on this graph the normai form capsuler I shipped w,ll havu to be rnultiplied by 4/3 also. This method takes into account the fact that.ibs shipment rate fci tho normal form c&psu!ss wil! be 3/4 that cf the special terms and lets both b represented by the sam 6 straight line. i From a linear least squares fit of the shipping data so far experienced, the results are that the completion of the shipping campaign will occur about 580 days from 6/28/89, the day when the first special form shipment was made. This results in a shipping completion date of ab 1 29,1991. The completion of the decontamination and the site release will take another 147 d (21 weeks) after the shipping is completed. This gives a final site release date of about June 1991. There are many things which can significantly affect the site release schedule. Some of them will delay release and some can speed it up. Unfortunately we have been experiencing only slow down variety so far in this program. schedule, we will use the above dates for site planning purposes.Until we can The choke point in the shipping campaign is now the decontamination rate of the Cs 137 cap WESF. If this rate could be speeded up (e.g. by going to three shift operation at WESF) then th shipping schedule would be shortened by about 6 months. This would move the site release date i earlier by approximately 6 months and would result in a project savings of between $12 M to DOE.
