Download or read book K Basin Sludge Water System Preliminary Hazard Analysis written by and published by . This book was released on 2001 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides the initial Preliminary Hazard Analysis (PHA) for the Spent Nuclear Fuel (SNF) Project, Sludge and Water System (SWS) subproject. The purpose of the K East (KE) basins SWS is to provide a system that will transfer the KE basins sludge from in-basin storage or source locations to containment and loadout for subsequent transport to T Plant for storage. The SWS will provide a system (Phase I) to retrieve and contain the identified as-settled sludge volume in the KE basin, while maintaining basin water clarity and associated radioactive control limits in accordance with basin operation requirements, and to support the Fuel Transfer System (FTS) and Debris Removal System (DRS). The SWS will also provide a system (Phase II) to retrieve and contain the remaining as-settled sludge volume in the K East basin, while maintaining basin water clarity and associated radioactive control limits in accordance with basin operation requirements. The SWS is in the conceptual design phase. A primary purpose of this PHA is to support the Conceptual Design Document (draft). As details of the SWS process and design are developed, this initial PHA will require revision. The K Basin Hazard Analysis (HNF-3960) documents the hazard analysis previously performed on the K basins including the multi-canister overpack (MCO) and support buildings. HNF-3960 will be updated later to reflect future SWS activities for sludge and water transfer to ensure that all hazards are included. All operational activities and energy sources associated with the SWS are evaluated in this hazard analysis. Using a systematic approach, this document identifies hazards created by abnormal operating conditions, external events (e.g., range fire), and natural phenomena hazards (e.g., earthquake) with the potential for causing undesirable consequences to facility workers, on-site individuals, the public, or the environment.

Download or read book Effects of Time Heat and Oxygen on K Basin Sludge Agglomeration Strength and Solids Volume written by and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sludge disposition will be managed in two phases under the K Basin Sludge Treatment Project. The first phase is to retrieve the sludge that currently resides in engineered containers in the K West (KW) Basin pool at ~10 to 18°C. The second phase is to retrieve the sludge from interim storage in the sludge transport and storage containers (STSCs) and treat and package it in preparation for eventual shipment to the Waste Isolation Pilot Plant. The work described in this report was conducted to gain insight into how sludge may change during long-term containerized storage in the STSCs. To accelerate potential physical and chemical changes, the tests were performed at temperatures and oxygen partial pressures significantly greater than those expected in the T Plant canyon cells where the STSCs will be stored. Tests were conducted to determine the effects of 50°C oxygenated water exposure on settled quiescent uraninite (UO2) slurry and a full simulant of KW containerized sludge to determine the effects of oxygen and heat on the composition and mechanical properties of sludge. Shear-strength measurements by vane rheometry also were conducted for UO2 slurry, mixtures of UO2 and metaschoepite (UO3 2H2O), and for simulated KW containerized sludge. The results from these tests and related previous tests are compared to determine whether the settled solids in the K Basin sludge materials change in volume because of oxidation of UO2 by dissolved atmospheric oxygen to form metaschoepite. The test results also are compared to determine if heating or other factors alter sludge volumes and to determine the effects of sludge composition and settling times on sludge shear strength. It has been estimated that the sludge volume will increase with time because of a uranium metal --> uraninite --> metaschoepite oxidation sequence. This increase could increase the number of containers required for storage and increase overall costs of sludge management activities. However, the volume might decrease because of decreases in the water-volume fraction caused by sludge solid reactions, compaction, or intergrowth and recrystallization of metaschoepite. In that case, fewer STSCs may be needed, but the shear strength would increase, and this could challenge recovery by water jet erosion and require more aggressive retrieval methods. Overall, the tests described herein indicate that the settled solids volume remains the same or decreases with time. The only case for which the sludge solids volumes increase with time is for the expansion factor attendant upon the anoxic corrosion of uranium metal to produce UO2 and subsequent reaction with oxygen to form equimolar UO2.25 and UO3 2H2O.

Download or read book Assessment of the Quantities and Distribution of K East Basin Floor Sludge Constituents written by and published by . This book was released on 1996 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Floor sludge constituent masses and their spatial distribution within K East Basin were calculated. This information will be beneficial in the assessing the acceptability of K Basin sludge in the Tank Waste Remediation System and in the design and/or operational practices related to retrieval and handling of this K Basin sludge. Calculations were made based on results from recent laboratory chemical and radionuclides analyses of sludge sampled from thirteen locations in K East main basin. This concentration data was mathematically processed to determine the various constituents concentration distribution throughout the basin floor. This data was further processed, along with data previously generated from the analysis of measured sludge depths, to give both basin total masses and associated spatial distribution of the various sludge constituents. Results of these calculations, showed that the major gravimetric constituents of the sludge are iron (1505 kg), uranium (1387 kg), aluminum, sodium and c2@15cium. Significant amounts of fissionable materials were also calculated: u (9.92 kg) and 239pU (3.42 kg). The calculated distribution of sludge constituent masses showed distinct patterns. Sludge constituent associated with corroded spent nuclear fuel were concentrated near the north-west corner of the basin. Aluminum and iron, and many other elements are mainly located near the mouth of the South Load Out Pit. A value of 10,200 Ci of alpha (5%) + beta (95%) radioactivity was calculated for the total basin floor sludge, and was concentrated near the north-west corner of the basin and near the Dummy Elevator Pit.

Book excerpt: Sludge samples from the canisters in the Hanford K East Basin fuel storage pool have been retrieved and analyzed. Both chemical and physical properties have been determined. The results are to be used to determine the disposition of the bulk of the sludge and to assess the impact of residual sludge on dry storage of the associated intact metallic uranium fuel elements. This report is a summary and review of the data provided by various laboratories. Although raw chemistry data were originally reported on various bases (compositions for as-settled, centrifuged, or dry sludge) this report places all of the data on a common comparable basis. Data were evaluated for internal consistency and consistency with respect to the governing sample analysis plan. Conclusions applicable to sludge disposition and spent fuel storage are drawn where possible.
Download or read book Updated Volumetric Expansion Factors for K Basin Sludge During Storage written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sludge has accumulated in the K East (KE) and K West (KW) Basins at the Hanford Site. This sludge contains metallic uranium and uranium oxides that will corrode, hydrate, and generate and consume gases during containerized storage. From these corrosion reactions, two sludge expansion mechanisms can be expected: 1) expansion of the volume of the sludge solids from the generation of corrosion oxidation products that occupy more space than the starting-state sludge; and 2) expansion of the bulk sludge volume from the retention of hydrogen gas bubbles. This report provides a review and updated projections of the volumetric expansion occurring due to corrosion and gas retention during the containerized storage of K Basin sludge. New design and safety basis volume expansion values are provided for the following sludge streams: KW Floor, KW North Loadout Pit, KW canister, and fuel piece sludge.
