A3175 . Analyses of Special Waste Problems Task Order No. 7 - Statement of Effort Evaluation of Decontamination Waste Characteristics
1.0 BACKGROUND
The NRC is reviewing Topical Reports on cement solidification of low-level radioactive wastes submitted by vendors to demonstrate that the I solidified waste products described have the 300-year structural stability required by 10 CFR Part 61. One of the waste streams described in these Topical Reports is wastes from decontamination of nuclear reactor components and systems. These reviews are complicated by recent developments in the !
solidification of all waste streams with cement, and by recent problems with ,
degradation of solidified waste forms that contained waste streams that have i characteristics similar to decontamination wastes. There is a need for better characterization of decontamination waste streams'through available literature in order to ensure that the reviews of these Topical Reports consider all of the technical considerations necessary to make the proper findings on whether cement solidified decontamination wastes will have the required structural stability.
The NRC is conducting laboratory research at Brookhaven National Laboratory (BNL) under FIN No. A3246, Decontamination Impacts on Solidification and Waste Disposal on several aspects of decontamination reagants and waste streams. It has been determined that testing that will be conducted under Tasks 3 and 4 of FIN No. A3246, as described in the FY89 S0W, can benefit from the characterization of the decontamination waste streams that will be conducted under this Task Order. Therefore, the results of this Task Order are to be produced in such a way that the information can be. utilized by the investigators doing the research under FIN No. A3246 for FY89 for development of the proposed test plans in Tasks 3 and 4, as well as being useful for review of Topical Reports on decontamination waste streams, as described above TM reforming organization (BNL) is providing technical assi' ance to the NRC m two other FI!+s (A3174 and A3951) on the reviews of the cement ic 3.dification Topical Reports described above, and has provided assistance in tri recent past on curing of waste forms made with portland cement binders and bitumen, on incidences involving degradation of cement waste forms, on waste form technical position testing criteria, and on cement solidification of wastes at the West Valley Nuclear Services Center at West Valley, NY. The NRC requires technical assistance from BNL under Task 3 of the S0W for FIN No.
A3175 - LLW Stability Problems and Guidance Development with characterization.
and evaluation of decontamination wastes.

i 2.0 WORK REQUIRED I l
The performing organization (BNL) shall provide facilities, technical staff, #
and support personnel to' perform the required work within the schedules and levels of effort defined in each of the following subtasks.
2.1 Subtask 1: Characterization of Decontamination Wastes BNL shall characterize decontamination wastes from available information. The characterization shall cons fder the physical and chemical behavior of decontamination wastes, including the chelating agents, complexing agents, and organic acids known to be used in decontamination processes. The characterization shall include information about the characteristics of decontamination solutions before processing and following processing in order to evaluate the significant chemical and physical properties of the final waste stream that is solidified. The characterization should lead to a better understanding of the complicated behavior of these waste streams in such a way l that it (1) will assist in determining the correct testing plan that should.be l developed under Task 3 of FIN No. A3246, and (2) will assist in the review of l Topical Reports on cement solidification of decontamination waste streams currently under review by BNL under FIN Nos. A3174 and A3951. BNL shall make recommendations on (1) what considerations to include in the testing to be conducted in Task 3 under FIN No. A3246 and (2) what technical aspects of i decontamination wastes should be important considerations in the review of Topicals for cement solidification of decontamination wastes. The results of this subtask shall be submitted to the NMSS PM as a draft technical letter ,
report in accordance with Section 3.3.1 of the S0W by August 1, 1989.
2.2 Subtask 2: Identification and Evaluation of Process Control Parameters for l Decontamination Waste Streams {
l BNL shall identify process control parameters which may be utilized to ,
effectively control waste processing of decontamination waste streams and l
obtain a final waste product that will meet Part 61 waste structural stability !
requirements. The process control parameters shall be identified using available information and the results of Subtask 1 of Task Order No. 6 of this FIN No. A3175. The identification of process control parameters shall include, but not be limited to, chemical composition, quantity of waste relative to binder, type and quantity of additives, pH, and temperature. BNL shall evaluate the identified process control parameters and determine a range of values, if possible, or sets of boundary conditions for parameters that will usually result in assurance of a final waste product that will meet the structural stability requirements. The results of this subtask shall be developed in such a way that the information can be utilized in the development of the proposed test plan for Task No. 3 under FIN No. A3246. The results of this subtask shall be submitted to the NMSS PM as a draft technical letter report in accordance with Section 3.3.1 of the S0W by September 1, 1989.
2.3 Subtask 3: Identification of Problem Ingredients in Decontamination Waste BNL shall identify any radiolytic and/or corrosion products that could possibly De included in the final waste stream of decontamination waste that may cause 1 degradation of solidified waste forms. BNL shall also evaluate the likelihood I of these radiolytic and/or corrosion products being in the final waste stream 2 i
e and causing the identified degradation problems. The identification and evaluation shall be performed utilizing existing information. BNL shall include an evaluation of the possibility of swelling of the bead resins that are part of the decontamination waste stream from irradiation and/or other causes in tne evaluatim of degradation problems. The results of this subtask shall be developed in such a way that the information can be utilized in the development of the proposed test plan to be developed in subtask 4 under FIN No. A3246. The results of this subtask shall be submitted to the NMSS PM as a draft technical letter report in accordance with Section 3.3.1 of the S0W by October 1, 1989.
2.4 Subtask 4: Meeting Attendance and Participation BNL shall allow for attendance at one meeting with NRC and possibly other NRC contractors and consultants as necessary to discuss the results of the work in subtasks 1 through 3 of this Task Order No. 7. The time of the meeting is not known at this time; however, the location will be the NRC Headquarters in l
Rockville, MD. The NMSS PM shall inform BNL of the~ arrangements for this meeting as early as possible. A report of this meeting by BNL personnel shall not be required as described in Section 3.2 of the S0W, unless otherwise instructed by the NMSS PM.
3.0 REPORTING REQUIREMENTS The performing organization (BNL) shall submit a draft technical letter report for subtasks I through 3 as described in Sections 2.1 through 2.3 of_ this Task Order No. 7. The draft technical letter reports are due on the days designated in Sections 2.1 through 2.3 of this Task Order. After review of the draft technical letter report, the NMSS PM will submit comments to BNL for consideration in preparing a final technical letter report. BNL shall submit final technical letter reports that include resolution of the comments on the draft technical letter reports submitted by the NMSS PM. The final technical l letter reports are due 15 days following the NMSS PM submittal of comments on the draft technical letter reports.
