“…This calculation is used to determine how much the low carbon steel would need to be modeled around the neutron beamline, so as to get an accurate calculation of the dose 10 m from the moderator face. The current model adds about 100 cm steel around the neutron beamline, this result agrees with the SNS calculation that also adds about 100 cm steel [3].…”

“…The second model with isodose contours is shown in Fig. 4, this result basically agrees with the SNS shielding calculation [3]. The SNS reduced the dose of radiation by about 6 orders of magnitude with a 180 cm shield and in this paper the dose of radiation was rduced by nearly 7 orders of magnitude with the 200 cm shield.…”

“…Calculations are being performed to optimize the beamline shielding design with the goal of minimizing the size of the shutter neutron beam stop, thereby reducing the costs and enhancing maintainability, as well as guaranteeing personal safety. A methodology of coupled Monte Carlo and multi-dimensional discrete ordinates methods has been utilized to perform the shielding analyses [3][4][5]. This work analyzed the shielding efficiency of the shutter neutron beam stop.…”

The construction of China Spallation Neutron Source (CSNS) has been initiated in Dongguan, Guangdong, China. Thus a detailed radiation transport analysis of the shutter neutron beam stop is of vital importance. The analyses are performed using the coupled Monte Carlo and multi-dimensional discrete ordinates method. The target of calculations is to optimize the neutron beamline shielding design to guarantee personal safety and minimize cost. Successful elimination of the primary ray effects via the two-dimensional uncollided flux and the first collision source methodology is also illustrated. Two-dimensional dose distribution is calculated. The dose at the end of the neutron beam line is less than 2.5 μSv/h. The models have ensured that the doses received by the hall staff members are below the standard limit required.

“…Rather than an exhaustive site characterization for all contaminants, media, and flow pathways, WAG 2 personnel will (1) focus on contaminants and pathways of greatest concern and (2) monitor and gather sufficient information for processes controlling or driving contaminant fluxes to construct an appropriate conceptual model for contaminant source areas and fluxes in WAG 2. This approach allows the early identification of remedial alternatives and focuses efforts on the gathering of data useful for evaluating alternatives to reduce risk (Miller 1993).…”

The waste management strategy is based on the generation and management of waste on a systematic basis using the most appropriate combination of waste reduction, segregation, treatment, storage, and disposal practices while protecting the environment and human health, maintaining as low as reasonably achievable limits. This plan contains provisions for safely and effectively managing soils and sediments, samphng water, decontamination fluids, and disposable personal protective equipment consistent with the U.S. Environmental Protection Agency guidance. This plan will be used in conjunction with the ORNL ER Program Waste Management Plan. R INTRODUCnONThis Project Waste Management Plan (PWMP) will be used in conjunction with the ORNL ER Program Waste Management Plan. This PWMP defines the criteria and methods to be used for managing waste generated during activities associated with Waste Area Grouping (WAG) 2 at Oak Ridge National Laboratory (ORNL). The waste management strategy is based on the generation and management of waste on a systematic basis using the most appropriate combination of waste reduction, segregation, treatment, storage, and disposal practices while protecting the environment and human health, maintaining as low as reasonably achievable (ALARA) Hmits. This plan contains provisions for safely and effectively managing soils and sediments, sampling water, decontamination fluids, and disposable personal protective equipment (PPE) consistent with the U.S. Environmental Protection Agency (EPA) guidance in Management of Investigation-Derived Waste During Site Investigation (EPA 1991) and best management practices. Consistent with EPA guidance, this plan is designed to protect the environment and the health and safety of workers and the public. It therefore specifies that investigationderived waste (IDW) and other wastes be managed to ensure that • costs associated with sample storage, analysis, transportation, and disposal are minimized;• additional pathways of contamination release are not created, and existing pathways are not enhanced;• a...

Preliminary shielding analysis for the CSNS target station monolith

et al. 2010

View full text Add to dashboard Cite

The construction of the China Spallation Neutron Source (CSNS) has been initiated at Dongguan, Guangdong, China. In spallation neutron sources the target station monolith is contaminated by a large number of fast neutrons whose energies can be as large as those of the protons of the proton beam directed towards the tungsten target. A detailed radiation transport analysis of the target station monolith is important for the construction of the CSNS. The analysis is performed using the coupled Monte Carlo and multi-dimensional discrete ordinates method. Successful elimination of the primary ray effects via the two-dimensional uncollided flux and first collision source methodology is also illustrated. The dose at the edge of the monolith is calculated. The results demonstrate that the doses received by the hall staff members are below the required standard limit.
