Railcar Waste Transfer system hydrostatic test
1997Co-Authors: S.d. EllingsonAbstract:Recent modifications have been performed on the T-Plant Railcar Waste Transfer System, This Acceptance Test Procedure (ATP) has been prepared to demonstrate that identified piping welds and mechanical connections incorporated during the modification are of high integrity and are acceptable for service. This will be achieved by implementation of a hydrostatic leak test.

Encasement pressurization after leaks in primary piping
2001Co-Authors: R.l. Schlosser, L.j. JulykAbstract:Preliminary evaluations of existing tank farm Waste Transfer system encasement piping pressure response to flowing Waste supernate following a large primary line leak indicate the potential to exceed current design conditions for the encasement piping system. The potential impact to design of the encasement piping systems is assessed in this paper. Based on the encasement pressure conditions reported, the existing encasement piping systems can perform their safety functions and are capable of withstanding the worst predicted pressure conditions for a large leak in the primary system. Testing is being conducted to validate parameters used in the completed preliminary supernate evaluations and to establish a basis for evaluation of slurry Transfer leaks. The results of these tests will be incorporated into the evaluations after results become available. This report provides the current status of encasement pressure analyses to determine suitable conditions for design of encasement piping within the tank farms Waste Transfer systems. This report provides results of preliminary evaluations, activities necessary to complete the evaluations, potential impacts on existing piping systems, and demonstration of adequacy of the existing encasement piping for withstanding higher pressure than the current design pressure without jeopardizing the safety function of the encasement piping systems tomore » direct the flow of leaked Waste from the primary line to a Waste Transfer-associated structure for detection (i.e., the encasement will direct Waste to a pit leak detector before there is any significant release of Waste to the environment).« less

Data quality objectives for TWRS privatization, phase 1: Tank Waste Transfer control
1999Co-Authors: D.l. BanningAbstract:The Phase 1 privatization contract (DOE-RL 1996) requires that the Project Hanford Management Contractors, on behalf of the U.S. Department of Energy, Richland Operations Office, deliver Waste feed in appropriate quantities and composition on schedule. The Feed Process Management Team (FPMT) was created with responsibility for establishing requirements, identifying and recommending baseline change control, assuring configuration management of tank contents (e.g., feed pedigrees), and requiring understanding among the various TWRS elements so the right feed is produced on schedule (Boston 1996). The FPMT has charged the Double Shell Tank (DST) Waste Inventory Control (WIC) (LMHC 1997) group to develop and implement the Waste configuration control needed to insure that our ability to deliver feed on schedule is not adversely impacted. The WIC group, which has representatives from engineering, environmental, operations, and Waste feed delivery, reviews proposed Waste Transfers and technical issues affecting the TWRS Waste inventory. The WIC group either approves proposed Transfers or, if a unanimous decision is not obtained, elevates approval to the FPMT. A representative from the FPMT is present at the WIC group meetings where Waste Transfer approvals are decided, and WIC relays information to the FPMT as needed. The TWRS operations include Waste inventory control,more » Waste consolidation, Waste Transfers, compatibility evaluations, feed staging for privatization, and technical issues affecting Waste Transfers. Pumping restrictions are outlined in Boston (1998). The mobilization, retrieval, Transfer, pretreatment, staging, and delivery of feed to the privatization contractor take place in the DST system. These tanks support multiple programs; therefore, the tank space must be allocated and controlled so as not to interfere with the delivery of feed by creating space bottlenecks or by significantly changing the composition or quantity of feed. Each feed tank selected for Phase 1 processing has been identified as a source of Waste for a particular feed envelope. These feed envelope descriptions are identified in the Phase 1 privatization contract.« less

Data quality objectives for TWRS privatization, phase 1: Tank Waste Transfer control
1998Co-Authors: D.l. BanningAbstract:The Phase 1 privatization contracts (DOE-M 1996) require that the Project Hanford Management Contractors, on behalf of the US Department of Energy, Richland Operations Office, deliver the appropriate quantities of the proper composition of feed on schedule. The Feed Process Management Team (FPMT) was created with responsibility for establishing requirements, identifying and recommending baseline change control, assuring correlation management of tank contents (e.g., feed pedigrees), and requiring understanding among the various TWRS elements so the right feed is produced on schedule (Boston 1996).

The TWRS Waste process includes Waste inventory control, Waste consolidation, Waste Transfers, compatibility, feed staging for privatization, and technical issues affecting Waste Transfers. Pumping restrictions are outlined in Wicks 1997. The mobilization, retrieval, Transfer, pretreatment, staging, and delivery of feed to the privatization contractors takes place in the DST system. These tanks support multiple programs; therefore, the tank space must be allocated and controlled so as not to interfere with the delivery of feed by creating space bottle-necks or by significantly changing the composition or quantity of feed. Each feed tank selected for Phase 1 processing has been identified as a source of Waste for a particular feed envelope. These feed envelope descriptions are identified in the Phase 1 privatization contracts.

Offsite Radiological Consequence Analysis for the Waste Transfer Leak
2003Co-Authors: B.d. ZimmermanAbstract:This document quantifies the offsite radiological consequence of the bounding Waste Transfer leak accident for comparison with the 25 rem Evaluation Guideline established in DOE-STD-3009, Appendix A. The bounding Waste Transfer leak accident is a large pipe break into a pit. The calculation offsite dose does not challenge the Evaluation Guidelines. Revision 2 incorporated comments received from the office of River Protection. The purpose of this calculation note is to document calculations performed in support of the evaluation of the bounding representative accident scenario for the Waste Transfer leak accident. The Waste Transfer leak accident has two representative accident scenarios: the fine spray into the air scenario and the large pipe break into a pit scenario. Both of these scenarios are evaluated in this calculation note, and a determination is made that the large pipe break into a pit scenario is bounding. Only the offsite radiological consequences are considered by this calculation note.

This research is aimed to evaluate health risk of VOCs among WTS personnel and provide a model for dispersion of VOCs. The Air Pollution Model (TAPM) is able to simulate WTS emissions dispersion over each town. Result GC-MS was used to analysis collected gas samples to detect and estimate carcinogenic and non-carcinogenic VOCs health risks. The total lifetime cancer risk values for the all personnel (3.30E-05), was more than acceptable limit (1.00E-06). Furthermore, hazard ratio (HR) of 1,2,3-trimethylbenzene, 1,3-dichloropropane, toluene, m,p-xylene and ethylbenzene were 3.7, 1.9 E-01, 4.4 E-03, 5.5 E-02 and 1.5 E-03, respectively, and total HR of the mentioned compounds were more than accepted limit (HR
