Evaluation of Flygt Propeller Xixers for Double Shell Tank (DST) High Level Waste Auxiliary Solids Mobilization

Description: The River Protection Project (RPP) is planning to retrieve radioactive waste from the single-shell tanks (SST) and double-shell tanks (DST) underground at the Hanford Site. This waste will then be transferred to a waste treatment plant to be immobilized (vitrified) in a stable glass form. Over the years, the waste solids in many of the tanks have settled to form a layer of sludge at the bottom. The thickness of the sludge layer varies from tank to tank, from no sludge or a few inches of sludge to about 15 ft of sludge. The purpose of this technology and engineering case study is to evaluate the Flygt{trademark} submersible propeller mixer as a potential technology for auxiliary mobilization of DST HLW solids. Considering the usage and development to date by other sites in the development of this technology, this study also has the objective of expanding the knowledge base of the Flygt{trademark} mixer concept with the broader perspective of Hanford Site tank waste retrieval. More specifically, the objectives of this study delineated from the work plan are described.

Installation Instructions (ETN-98-0005) S-farm Overground Transfer (ogt) System Valve Pit 241-S-B to Valve Pit 241-S-D

Description: Lockheed Martin Hanford Corporation (LMHC) is providing an overground transfer (OGT) system for use in saltwell pumping of the 241-S-Tank Farm. Fluor Daniel Northwest (FDNW) was requested to support the effort by completing the design of the OGT system and completing the construction of the encasement pipe and encasement pipe support system. FDNW will also install the concrete shielding blocks for the OGT system. The shielding block system will provide a vehicle barrier for protection of the OGT line and will provide a radiation barrier for operations personnel. LMHC is responsible for the regulatory compliance of the entire transfer system. This installation instruction covers the encasement piping, pipe supports, heat tracing, thermal insulation, leak detectors, temperature indicators, and the shielding blocks. Installation of the primary (inner) pipe and associated equipment was completed at a previous time and the integrity of the primary piping will be confirmed by LMHC prior to operation of the system.

Double Shell Tank (DST) Monitor and Control Subsystem Specification

Description: This specification establishes the performance requirements and provides references to the requisite codes and standards to be applied during design of the Double-Shell Tank (DST) Monitor and Control Subsystem that supports the first phase of Waste Feed Delivery. This subsystem specification establishes the interface and performance requirements and provides references to the requisite codes and standards to be applied during the design of the Double-Shell Tank (DST) Monitor and Control Subsystem. The DST Monitor and Control Subsystem consists of the new and existing equipment that will be used to provide tank farm operators with integrated local monitoring and control of the DST systems to support Waste Feed Delivery (WFD). New equipment will provide automatic control and safety interlocks where required and provide operators with visibility into the status of DST subsystem operations (e.g., DST mixer pump operation and DST waste transfers) and the ability to manually control specified DST functions as necessary. This specification is intended to be the basis for new project/installations (W-521, etc.). This specification is not intended to retroactively affect previously established project design criteria without specific direction by the program.

Waste Feed Delivery System Phase 1 Preliminary RAM Analysis [SEC 1 and 2]

Description: This report presents the updated results of the preliminary reliability, availability, and maintainability (RAM) analysis of selected waste feed delivery (WFD) operations to be performed by the Tank Farm Contractor (TFC) during Phase I activities in support of the Waste Treatment and Immobilization Plant (WTP). For planning purposes, waste feed tanks are being divided into five classes in accordance with the type of waste in each tank and the activities required to retrieve, qualify, and transfer waste feed. This report reflects the baseline design and operating concept, as of the beginning of Fiscal Year 2000, for the delivery of feed from three of these classes, represented by source tanks 241-AN-102, 241-AZ-101 and 241-AN-105. The preliminary RAM analysis quantifies the potential schedule delay associated with operations and maintenance (OBM) field activities needed to accomplish these operations. The RAM analysis is preliminary because the system design, process definition, and activity planning are in a state of evolution. The results are being used to support the continuing development of an O&M Concept tailored to the unique requirements of the WFD Program, which is being documented in various volumes of the Waste Feed Delivery Technical Basis (Carlson. 1999, Rasmussen 1999, and Orme 2000). The waste feed provided to the WTP must: (1) meet limits for chemical and radioactive constituents based on pre-established compositional envelopes (i.e., feed quality); (2) be in acceptable quantities within a prescribed sequence to meet feed quantities; and (3) meet schedule requirements (i.e., feed timing). In the absence of new criteria related to acceptable schedule performance due to the termination of the TWRS Privatization Contract, the original criteria from the Tank Waste Remediation System (77443s) Privatization Contract (DOE 1998) will continue to be used for this analysis.

Evaluation of helium impurity impacts on Spent Nuclear Fuel project processes (OCRWM)

Description: This document identifies the types and quantities of impurities that may be present within helium that is introduced into multi-canister overpacks (MCO)s by various SNF Project facilities, including, but not limited to the Cold Vacuum Drying (CVD) Facility (CVDF). It then evaluates possible impacts of worst case impurity inventories on MCO drying, transportation, and storage processes. Based on the evaluation results, this document: (1) concludes that the SNF Project helium procurement specification can be a factor-of-ten less restrictive than a typical vendor's standard offering (99.96% pure versus the vendor's 99.997% pure standard offering); (2) concludes that the CVDF's current 99.5% purity requirement is adequate to control the quality of the helium that is delivered to the MCO by the plant's helium distribution system; and (3) recommends specific impurity limits for both of the above cases.

Design analysis of 2,000 lb JIB crane for chemical lab

Description: A 2,000 lbf jib crane is needed to replace an existing 1,000 lbf jib crane in the Chemical Lab (Building MO-733). The existing 1,000 lbf jib crane (to be replaced) has a 174 boom (I-beam). The crane is attached to the wall through two brackets (about 8 1/2-ft apart). The boom is attached to the lower bracket, and a supporting rod is attached to the upper bracket. The supporting rod is attached to the boom at about 8-ft from the free end. After preliminary studies and discussions, it was decided to construct the new jib crane from two perpendicular I-beams (L-shape) without a supporting rod. The crane is to be supported on the wall through the two lower existing brackets (about 5-ft apart). The boom is to be 20-ft long cantilever (the horizontal I-beam). The vertical I-beam is to be attached to the lower two existing brackets to support the jib crane to the wall. This construction is to be similar to another existing 1,000 lbf jib crane (L-shape) in the lab. The purpose of this document is to perform a design analysis for the proposed 2,000 lbf jib crane to determine suitable sizes of members and configuration of the new jib crane assembly. After construction, if the as-built assembly differs from the 2,000 lbf jib crane as proposed in this document, a revision of this analysis needs to be performed to confirm the acceptability of the as-built assembly.

Engineering Task Plan for the Development of Footclamp

Description: The Rotary Mode Core Sampling Trucks (RMCSTs) currently use a footclamp that utilizes a wedge design to secure the drill string. On June 18, 1998, a problem occurred while core sampling operations were being conducted. Approximately 28 ft. of drill string was inadvertently dropped into tank 241-SX-102. The root cause of this occurrence was determined to be inadequate or defective design of the footclamp being used. The footclamp in use during this occurrence relied on a wedge-type design that gripped the drill string tighter as the weight of the drill string was increased. The MAXIDRILL Model 3030 Footclamp does not rely on a wedge effect to hold the drill string; it uses spring force to engage the jaws with the drill string. The use of the MAXIDRILL Model 3030 Footclamp should eliminate any further problems of this nature and allow corrective action 2 in section 26 of the related occurrence report (RT-PHMC-TANKFARM-1998-0064) to be completed. Modifications of the base of the MAXIDRILL Model 3030 Footclamp are necessary to decrease the possibility of an injury due to the exposed jaws. Also, the plan for sampling tank 241-2-361 calls for a footclamp that will allow for total containment when the footclamp is connected to a tank riser. The need for a footclamp with total containment capabilities, and the design of a safer base for the MAXIDRILL Model 3030 Footclamp can be satisfied in the same task, The re-design of the base of the footclamp will allow for total containment while still being suitable for ''normal'' RMCS operations and improving the safety of the footclamp. This Engineering Task Plan (ETP) is the management plan document for accomplishing the identified tasks. Any changes in scope of the ETP shall require formal direction by the Characterization Engineering manager.
