Analysis of Radioactive Releases During Proposed Demolition Activities for the 224-U and 224-UA Buildings

Description: Atmospheric dispersion modeling has been conducted in support of the demolition of the 224-U and 224-UA buildings using estimated release rates to provide information on the location and levels of radioactive contamination that may be expected. The facilities surrounding the UO3 plant have the potential to affect dispersion patterns through various meteorological phenomena, including building wake effects. Hourly meteorological data collected over a 5-year period were used to examine the effects of wind speed, direction, and stability on projected concentrations of contaminants in air and deposited on nearby surfaces. The modeling results indicate that the radiological exposures from the planned demolition efforts will be below the designated limits for air and soil exposures.

Concrete Dust Suppression System. Innovative Technology Summary Report

Description: The improved technology is a water-based dust suppression system for controlling concrete dust generated by demolition equipment, in this case a demolition ram. This demonstration was performed to assess the effectiveness of this system to (1) minimize the amount of water used to suppress potentially contaminated dust, (2) focus the water spray on the dust-generating source and (3) minimize the dust cloud generated by the demolition activity. The technology successfully reduced the water required by a factor of eight compared to the traditional (baseline) method, controlled the dust generated, and permitted a reduction in the work force. The water spray can be focused at the ram point, but it is affected by wind. Prior to the use of this dust control system, dust generated by the demolition ram was controlled manually by spraying with fire hoses (the baseline technology). The improved technology is 18% less expensive than the baseline technology for the conditions and parameters of this demonstration, however, the automated system can save up to 80% versus the baseline whenever waste water treatment costs are considered. For demolishing one high-walled room and a long slab with a total of 413 m{sup 3} (14,580 ft{sup 3}) of concrete, the savings are $105,000 (waste water treatment included). The improved technology reduced the need for water consumption and treatment by about 88% which results in most of the savings.

Description: The Savannah River Site (SRS) has produced Special Nuclear Materials (SNMs) starting in the early 1950's to the mid 1970's for the Atomic Energy Commission (AEC) and from the mid 1970's to the present for the Department of Energy (DOE). In that time, over 1,000 facilities have been built in the sixteen (16) operational areas of the eight hundred (800) square kilometer site. Over the years, many of the facilities have been dispositioned by the DOE as inactive. In FY-03, DOE identified two hundred and forty-seven (247) (inactive or soon to be inactive) facilities that required demolition. Demolition work was scheduled to start in FY-04 and be completed in the first quarter of FY-07. Two-hundred and thirty-nine (239) of these facilities have been demolished employing Routine demolition techniques. This presentation reviews and discusses two (2) of the eight (8) Non-Routine demolitions Facilities, 420-D ''The Concentrator Facility'', and 421-D ''The Finishing Facility''.

Description: The U Plant geographic zone (UPZ) occupies 0.83 square kilometers on the Hanford Site Central Plateau (200 Area). It encompasses the U Plant canyon (221-U Facility), ancillary facilities that supported the canyon, soil waste sites, and underground pipelines. The UPZ cleanup initiative coordinates the cleanup of the major facilities, ancillary facilities, waste sites, and contaminated pipelines (collectively identified as ''cleanup items'') within the geographic zone. The UPZ was selected as a geographic cleanup zone prototype for resolving regulatory, technical, and stakeholder issues and demonstrating cleanup methods for several reasons: most of the area is inactive, sufficient characterization information is available to support decisions, cleanup of the high-risk waste sites will help protect the groundwater, and the zone contains a representative cross-section of the types of cleanup actions that will be required in other geographic zones. The UPZ cleanup demonstrates the first of 22 integrated zone cleanup actions on the Hanford Site Central Plateau to address threats to groundwater, the environment, and human health. The UPZ contains more than 100 individual cleanup items. Cleanup actions in the zone will be undertaken using multiple regulatory processes and decision documents. Cleanup actions will include building demolition, waste site and pipeline excavation, and the construction of multiple, large engineered barriers. In some cases, different cleanup actions may be taken at item locations that are immediately adjacent to each other. The cleanup planning and field activities for each cleanup item must be undertaken in a coordinated and cohesive manner to ensure effective execution of the UPZ cleanup initiative. The UPZ zone cleanup implementation plan (ZCIP) was developed to address the need for a fundamental integration tool for UPZ cleanup. As UPZ cleanup planning and implementation moves forward, the ZCIP is intended to be a living document that will provide a focal point for integrating UPZ ...

Weldon Spring Site Remedial Action Project approach to building dismantlement and demolition

Description: When remediation began at the Weldon Spring Site Remedial Action Project (WSSRAP), there were 41 buildings on site. Twenty-nine of these buildings were ancillary structures and were not used for processing radioactive material. Most of these have been torn down. The remaining 12 buildings were used for uranium and thorium processing or were major support structures, such as the laboratory. Two of the buildings were major processing operations occurred were successfully demolished in February of this year. Demolition of all structures will be complete in September of this year. To give an understanding of the magnitude of the work, the following is a description of the physical characteristics of the green salt building. This building was used to convert brown oxide (UO3) to green salt (UF4), which is the last intermediate step in purifying the mostly yellow cake feed material into uranium metal.

NEPA and NHPA- successful decommissioning of historic Manhattan Project properties at Los Alamos National Laboratory, Los Alamos, New Mexico

Description: This paper describes experiences at Los Alamos National Laboratory during the process of planning and executing decommissioning and decontamination activities on a number of properties constructed as part of the Manhattan project. Many of these buildings had been abandoned for many years and were in deteriorating condition, in addition to being contaminated with asbestos, lead based paints and high explosive residues. Due to the age and use of the structures they were evaluated against criteria for the National Register of Historic Places. This process is briefly reviewed, along with the results, as well as actions implemented as a result of the condition and safety of the structures. A number of the structures have been decontaminated and demolished. Planning is still ongoing for the renovation of one structure, and the photographic and drawing records of the properties is near completion.

Ground motion measurements from the demolition of steel towers

Description: Steel towers from a decommissioned heavy water plant were to be demolished. Ground motions due to the proposed felling were estimated in order to assess the structural integrity of neighboring buildings and piping systems. The extraction towers were 125 feet (38.1 m) high in two sizes: 6.5 and 11 feet (1.98 and 3.35 m) inside diameters weighing 215 X 10{sup 3} and 470 X 10{sup 3} lb (956 X 10{sup 3} and 2.1 X 10{sup 6} N). The total potential energy of the tower collapse was about 15 X 10{sup 6} and 32 X 10{sup 6} ft-lb (20.3 X 10{sup 6} and 43.4 X 10{sup 6} Nm) for the small and large towers, respectively. The ground motion predictions were based on a credible theoretical relationship with constants estimated from data available for a different location at the site for dynamic compaction with an energy input an order of magnitude less than that for the towers. Due to the uncertainty of prediction of ground motions a coefficient of variation of 2.0 was used in the structural assessment. Ground motion from the collapse of the extraction towers were monitored by several 3- and 6-components seismographs. Recorded measurements indicated that the ground motion was less than the predicted values. Peak radial motions were approximately equal to the vertical ones. Video tapes of the demolition suggested significant internal energy losses. The measurements suggested that the tower potential energy conversion to dynamic impact energy was about 25 percent. 7 figs.

Programmatic agreement among the USDOE/RL Operations Office, the Advisory Council on Historic Preservation, and the WA State Historic Preservation Office for the maintenance, deactivation, alteration and demolition of the built environment on the Hanford Site, Washington

Description: This Programmatic Agreement (PA) addresses the built environment (i.e., buildings and structures) constructed during the Manhattan Project and Cold War Era periods of Hanford`s operational history. As such it encompasses the years 1943 through 1990. The identification, evaluation, and treatment of buildings and historic archeological remains on the Hanford Site predating 1943 will be accomplished through Sections 800.4 through 800.6 of the Council`s regulations. This PA will be in effect from the date of signature until September 30, 2000. Completion of the Sitewide Treatment Plan established under this PA satisfies all Section 106 requirements for identification, evaluation, and treatment necessary for all undertakings, up to and including demolition which may affect Manhattan Project and Cold War Era properties. This PA may be extended if the Sitewide Treatment Plan has not been completed by the end of FY 2000. Identification, evaluation, and treatment of properties constructed on the Hanford Site after 1990 will be handled pursuant to the regulations in effect at the time such properties are eligible for review.

Site wide integration of the Rocky Flats closure project

Description: The prime contractor for the Rocky Flats Closure Project (RFCP), Kaiser-Hill, in concert with the Department of Energy--Rocky Flats Field Office (DOE-RFFO) has applied a fully integrated, life-cycle, critical path schedule and work planning system to manage the work that is required to close the Site. The closure of the Site is complex, in that it houses over 700 facilities, 19,600 kilograms of Special Nuclear Material (Plutonium and Uranium), and over 160,000 cubic meters of Transuranic, Low Level, and Hazardous Waste. The deactivation, decommissioning, decontaminating, and demolition of this large number of facilities, while at the same time accommodating difficult on-going activities, significantly increases the sophistication required in the planning process. The Rocky Flats team has overcome these difficulties by establishing a money oriented critical path process, to provide a least-cost avenue to supporting on-going activities and a line-of-balance process for production oriented activities. These processes, when integrated with a typical activity-based project planning system, guide the way to the shortest and most cost-effective course for the closure of the Rocky Flats Site.

Sandia National Laboratories/New Mexico Facilities and Safety Information Document [NOTE: Volume I, Chapters 2 through 5]

Description: The Facilities Business Unit, which includes the Operations and Engineering Center (7800) and the Facilities Management Center (7900), coordinates decisions about the management of facilities, infrastructure, and sites. These decisions include the following: New construction, including siting; Rehabilitation, and renovation; Relocation; Mothballing; Decontamination and decommissioning; and Demolition. Decisions on these matters flow from a corporate decision process in which SNL directors and vice presidents identify the facility and infrastructure requirements for carrying out work for DOE and other customers. DOE and any non-DOE owners of real estate that is leased or permitted to DOE for SNL/NM use must concur with this identification of requirements. Decision-making follows procedures required by DOE and requirements defined by SNL/NM program executives. See Sandia National Laboratories (1997e), Part II, ''Desired Future State and Strategy,'' and appendices to Sandia National Laboratories (1997e) for more information about planning and decision processes. Decisions on siting take surrounding land uses into account and draw on environmental baseline information maintained at SNL/NM. For environmental baseline and land use information, see Sandia National Laboratories (1999).
