WHC-SD-WM-TP-451, REV 1

2.1 GENERAL SAFETY ISSUES

2.1.1 Safety Screening

The Tank Safety Screening Data Quality Objective (Dukelow et al. 1995) describes the sampling and analytical requirements that are used to screen tank waste for unidentified safety issues. Analytical requirements for tank safety screening are energetics, total alpha activity, moisture content, density and flammable gas concentration. Based on the these analytical results, additional analysis may be performed.

2.1.2 Vapor Safety Screening

All 177 underground tanks must be vapor-sampled for organic solvent screening in accordance with the Recommendation 93-5 Implementation Plan (DOE-RL 1996a). Organic solvent screening will be performed using the Scope Increase of "Data Quality Objective to Support Resolution Of the Organic Complexant Safety Issue" Rev. 2 (Cash 1996b). The primary vapor analyses conducted will determine Total Non-methane Hydrocarbon content. All previous vapor samples were analyzed for Total Non-methane Hydrocarbon content.

Tank U-102 is passively ventilated. Information needs for vapor sampling and analyses of passively ventilated tanks must satisfy Data Quality Objectives for Tank Hazardous Vapor Safety Screening (Osborne and Buckley 1995). The primary analyses employed will determine flammable gas, organic vapor, permanent gas, and moisture content in the tank dome space. Based on these analytical results, additional analysis may be performed.

2.2 SPECIFIC SAFETY ISSUES

2.2.1 Ferrocyanide

needs are currently identified for this program element. This tank is not on the Ferrocyanide Watch List; therefore, no information

2.2.2 Organic Phenomenology

Tank U-102 has been identified as in scope of the organic'DQ0 by either the Data Quality Objective to Support Resolution of the Organic Complexant Safety Issue (Turner et al. 1995) or the Scope Increase of "Data Quality Objective to Support Resolution Of the Organic Complexant Safety Issue" Rev. 2 (Cash 1996b). The primary waste analyses conducted will determine the TOC, energetics, and moisture content.

2.2.3 Flammable Gas

Tank U-102 has not been identified as in scope of the flammable gas DQO by either the Flammable Gas Safety Program: Data Requirements for Core Sample Analysis Developed through the Data Quality Objectives Process (McDuffie 1995) or the Application of "Flammable Gas Tank Safety Program: Data Requirements For Core Sampling Analysis Developed Through the Data Quality Objectives Process" Rev. 2 (Cash 1996a). Therefore, no flammable gas safety program information needs are currently identified for this tank.

2.2.4 Vapor Space Phenomenology

item.

2.2.5 Critical i ty

No information other than that for the general safety issue of tank U-102 is currently identified for this program element. However, if the general safety screening of tank U-102 identifies a potential criticality concern, analyses for fissile materials, and neutron sorbers and poisons will be performed as identified in the safety screening DQO (Dukelow et al. 1995).

2.2.6 High Heat Load

needs are currently identified for this program element.

No information needs from tank U-102 have been identified for this program

Tank U-102 is not on the High Heat Watch List; therefore, no information

2.3 CONTINUOUS OPERATIONS

2.3.1 Compati bi 1 i ty/Stabi 1 ization

Tank U-102 waste was sampled to determine compatibility. Sampling and analysis requirements were performed according to theData Quality Objectives for Tank Farms Waste Compatibility Program (Fowler 1995). The analyses employed were for anions, cations, pH, physical properties, radionuclides, TOC, total uranium, transuranics, and solids content, and moisture content.

2.3.2 Evaporator

This section does not apply to tank U-102.

2.3.3 Caustic Mitigation

No composition specification is required for tank U-102 (WHC 1996).

2.4 DOUBLE-SHELL TANK WASTE ANALYSIS PLAN

This section does not apply because tank U-102 is a single-shell tank.

2.5 DISPOSAL

2.5.1 Retrieval

Current retrieval needs (Bloom and Nguyen 1995) do not call for test samples to be taken from tank U-102.

2.5.2 Process Testing

Tank U-102 has not been identified as a bounding tank for the pretreatment/ disposal process development strategy (Kupfer et al. 1995). Even though tank U-102 is not a bounding tank, a portion of archive sample material may be

3

WHC-SO-WM-TP-451, REV 1

requested for pretreatment testing. The pretreatment strategy does not require any specific analyses to be conducted on the samples.

2.5.3 Privatization

This section does not apply because tank U-102 has not been chosen to represent a waste envelope as given in the TWRS Privatization Request for Proposal (RFP) (DOE-RL 1996b).

2.6 HISTORICAL MODEL EVALUATION

Tank U-102 is in scope of revision 0 of the Historical DQO. This tank has been sampled prior to the release of revision 1 of the Historical DQO or incorporation of revision 1 ofthe Historical DQO into this Tank Characterization Plan; therefore, requirements for this program element are identified in revision 0 of the Historical Model Evaluation Data Requirements (Simpson and McCain 1995) which requires sampling and analysis for energetics, moisture content, TOC, total uranium, density, cations, anions, and radionuclides.

3.0 HOW INFORMATION WILL BE OBTAINED

The number of samples required to characterize a tank is a function of waste heterogeneity and the desired confidence to make a correct decision. directed by the safety screening DQO, if inadequate information exists to determine an appropriate number of samples, two vertical profiles will be obtained. These vertical profiles may be obtained using core, auger (for shallow tanks), or grab samples. If analysis of these profiles reveals that additional profiles are necessary to meet data needs, more sample profiles will be requested.

4.0 PRIORITY OF INFORMATION REQUIREMENTS

4.1 Characterization Basis

The priorities of all the tanks were determined by addressing safety, disposal, and characterization issues in the Tank Waste Characterization Basis (Brown et al. 1996) document. references are: flammable gas (McDuffie 1995, Cash 1996a), organic fuel phenomenology (Turner et al. 1995, Cash 1996b), tank safety screening (Dukelow et al. 1995), vapor screening (DOE-RL 1996a, Cash 1996b), vapor space phenomenology (DOE-RL 1996a) and ferrocyanide (Meacham et al. 1995). The disposal issues with their respective references are: privatization (Slankas and Kupfer 1995), process testing (Kupfer et al. 1995), and retrieval (Bloom and Nguyen 1995). The characterization issue with its respective reference is the historical model evaluation (Simpson and McCain 1996). These issues were ranked by priority in the Meeting Minutes o f April 26 and 30, 1996 Meetings To Determine TWRS Issue Priorities (TWRS Technical Basis 1996).
