Recommendations and Justifications for Modifications for Use Restrictions Established under the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office Federal Facility Agreement and Consent Order with ROTC 1, Revision No. 0 (open access)

Recommendations and Justifications for Modifications for Use Restrictions Established under the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office Federal Facility Agreement and Consent Order with ROTC 1, Revision No. 0

Many Federal Facility Agreement and Consent Order (FFACO) Use Restrictions (URs) have been established at various corrective action sites (CASs) as part of FFACO corrective actions (FFACO, 1996; as amended January 2007). Since the signing of the FFACO in 1996, practices and procedures relating to the implementation of risk-based corrective action (RBCA) have evolved. This document is part of an effort to re-evaluate all FFACO URs against the current RBCA criteria (referred to in this document as the Industrial Sites [IS] RBCA process) as defined in the Industrial Sites Project Establishment of Final Action Levels (NNSA/NSO, 2006c). Based on this evaluation, the URs were sorted into the following categories: 1. Where sufficient information exists to determine that the current UR is consistent with the RCBA criteria 2. Where sufficient information exists to determine that the current UR may be removed or downgraded based on RCBA criteria. 3. Where sufficient information does not exist to evaluate the current UR against the RCBA criteria. After reviewing all the existing FFACO URs, the 49 URs addressed in this document have sufficient information to determine that these current URs may be removed or downgraded based on RCBA criteria. This document presents recommendations on modifications …

Sensitivity of numerical dispersion modeling to explosive source parameters (open access)

Sensitivity of numerical dispersion modeling to explosive source parameters

The calculation of downwind concentrations from non-traditional sources, such as explosions, provides unique challenges to dispersion models. The US Department of Energy has assigned the Atmospheric Release Advisory Capability (ARAC) at the Lawrence Livermore National Laboratory (LLNL) the task of estimating the impact of accidental radiological releases to the atmosphere anywhere in the world. Our experience includes responses to over 25 incidents in the past 16 years, and about 150 exercises a year. Examples of responses to explosive accidents include the 1980 Titan 2 missile fuel explosion near Damascus, Arkansas and the hydrogen gas explosion in the 1986 Chernobyl nuclear power plant accident. Based on judgment and experience, we frequently estimate the source geometry and the amount of toxic material aerosolized as well as its particle size distribution. To expedite our real-time response, we developed some automated algorithms and default assumptions about several potential sources. It is useful to know how well these algorithms perform against real-world measurements and how sensitive our dispersion model is to the potential range of input values. In this paper we present the algorithms we use to simulate explosive events, compare these methods with limited field data measurements, and analyze their sensitivity to input parameters. …

Incorporation of an explosive cloud rise code into ARAC's (Atmospheric Release Advisory Capability) ADPIC transport and diffusion model (open access)

Incorporation of an explosive cloud rise code into ARAC's (Atmospheric Release Advisory Capability) ADPIC transport and diffusion model

The US Department of Energy's Atmospheric Release Advisory Capability (ARAC) supports various government agencies by modeling the transport and diffusion of radiological material released into the atmosphere. ARAC provides this support principally in the form of computer-generated isopleths of radionuclide concentrations. In order to supply these concentration estimates in a timely manner, a suite of operational computer models is maintained by the ARAC staff. One primary tools used by ARAC is the ADPIC transport and diffusion computer model. This three-dimensional, particle-in-cell code simulates the release of a pollutant into the atmosphere, by injecting marker particles into a gridded, mass-consistent modeled wind field. The particles are then moved through the gridded domain by applying the appropriate advection, diffusion, and gravitational fall velocities. A cloud rise module has been incorporated into ARAC's ADPIC dispersion model to allow better simulation of particle distribution early after an explosive release of source material. The module is based on the conservation equations of mass, momentum, and energy, which are solved for the cloud radius, height, temperature, and velocity as a function of time. 6 refs., 5 figs., 2 tabs.

Active Commuter Rail Agency Service Contracts (open access)

Active Commuter Rail Agency Service Contracts

Correspondence issued by the Government Accountability Office with an abstract that begins "Commuter rail is an important part of the transportation system in many cities and regions in our country, providing more than 420 million passenger trips in 2005. Although several of the largest commuter rail agencies hire their own employees, many agencies contract with other companies, including Amtrak, freight railroads, and private rail operators, to provide services that are critical to running the agencies' trains. These contracted services include providing crews to operate trains (train operations); maintenance of equipment (MOE), including maintenance of train cars and locomotives; dispatching train traffic; and maintenance of way (MOW), which involves maintaining the track, signals, and other track infrastructure. Commuter rail agencies can obtain these services by opening contracts to competition or through noncompetitive negotiations with a service provider. Congress asked us to provide information on the service arrangements between commuter rail agencies and other companies. Accordingly, we addressed the following questions: (1) How many currently active commuter rail service contracts were obtained through competitive and noncompetitive processes? (2) What differences, if any, are there between competitively and noncompetitively negotiated contracts?"

Evaluation of the Atmospheric Release Advisory Capability emergency response model for explosive sources (open access)

Evaluation of the Atmospheric Release Advisory Capability emergency response model for explosive sources

The Atmospheric Release Advisory Capability (ARAC) at the Lawrence Livermore National Laboratory (LLNL) uses a modeling system to calculate the impact of accidental radiological or toxic releases to the atmosphere anywhere in the world. Operated for the US Departments of Energy and Defense, ARAC has responded to over 60 incidents in the past 18 years, and conducts over 100 exercises each year. Explosions are one of the most common mechanisms by which toxic particulates are injected into the atmosphere during accidents. Automated algorithms with default assumptions have been developed to estimate the source geometry and the amount of toxic material aerosolized. The paper examines the sensitivity of ARAC`s dispersion model to the range of input values for explosive sources, and analyzes the model`s accuracy using two field measurement programs.

Use of field experimental studies to evaluate emergency response models (open access)

Use of field experimental studies to evaluate emergency response models

The three-dimensional diagnostic wind field model (MATHEW) and the particle-in-cell atmospheric transport and diffusion model (ADPIC) are used by the Atmospheric Release Advisory Capability to estimate the environmental consequences of accidental releases of radioactivity into the atmosphere. These models have undergone extensive evaluations against field experiments conducted in a variety of environmental settings ranging from relatively flat to very complex terrain areas. Simulations of tracer experiments conducted in a complex mountain valley setting revealed that 35 to 50% of the comparisons between calculated and measured tracer concentrations were within a factor of 5. This may be compared with a factor of 2 for 50% of the comparisons for relatively flat terrain. This degradation of results in complex terrain is due to a variety of factors such as the limited representativeness of measurements in complex terrain, the limited spatial resolution afforded by the models, and the turbulence parameterization based on sigma/sub theta/ measurements to evaluate the eddy diffusivities. Measurements of sigma/sub theta/ in complex terrain exceed those measured over flat terrain by a factor of 2 to 3 leading to eddy diffusivities that are unrealistically high. The results of model evaluations are very sensitive to the quality and the representativeness of …
