2. Shielding and dosimetry

Oral

The Facility for Rare Isotope Beams (FRIB) at Michigan State University in East Lansing, Michigan, USA has transitioned from being a construction project to user operations for nuclear science experiments. FRIB is designed for the production of rare-isotope beams from in-flight fragmentation and fission of primary beams of stable isotopes ranging from oxygen to uranium with energies up to 200...

11. Shielding at the European Spallation Source: From Monte Carlo simulations to Reality

2. Shielding and dosimetry

Oral

The European Spallation Source is currently being constructed in the Lund, Sweden. As expected for a megawatt class facility, the need for shielding is high, extensive and costly. In support of the project a large number of Monte Carlo particle transport calculations have been performed. As for any simulations, even if one attempts to simulate everything in details, reality will not always...

2. Shielding and dosimetry

Oral

The design of the Second Target Station (STS) at Oak Ridge National Laboratory’s (ORNL’s) Spallation Neutron Source (SNS) is currently underway [1]. STS will operate at a power of 700 kW with short pulses, less than 1 s, and a repetition rate of 15 Hz. The new target will be a rotating water-cooled tungsten target, which will have two coupled cryogenic moderators filled with liquid...

55. Simulation of Spallation Target Activation and Cask Dose Shielding

2. Shielding and dosimetry

Oral

During the 2022 maintenance outage, we are installing a new generation of spallation target-moderator-reflector-shield (TMRS), known as Mark-IV for Manuel Lujan Jr. Neutron Scattering Center (Lujan Center) at the Los Alamos Neutron Science Center (LANSCE). This paper discusses the activation anal-ysis of the previous target Mark III, in service 2010-2021. The TMRS employs a split target...

21. THE ORNL R2S CODE SUITE (ORCS) FOR SHUTDOWN DOSE RATE SIMULATIONS

Bor Kos (ORNL)

2. Shielding and dosimetry

Oral

Current experimental fusion systems and conceptual designs of fusion pilot plants (FPPs) are growing in complexity and size. Several radiation metrics are crucial to the safe operation of fusion machines, including the shutdown dose rate (SDDR). SDDR is caused by decay gamma rays from radionuclides that become activated by neutrons during the operation of a fusion system. The two...
