Session 5: Code Benchmarking & Intercomparison / Induced Radioactivity & Decommissioning

• Mikhail Kostin (Thomas Jefferson Laboratory)

40. Activation benchmarking of metals by 9.6 GeV electrons at PAL-XFEL

5. Code benchmarking and intercomparison

Oral

In our previous work [1], samples of low carbon steel, stainless steel, aluminum and copper were irradiated in the stray radiation field results from the 9.6 GeV electron beam hitting a thick copper target at the PAL-XFEL main beam dump bunker. The induced activity concentration in the samples were measured using gamma-ray spectroscopy and were compared with the old version of FLUKA, 2011.2x....

14. Overview of benchmark studies at the CERN Shielding Benchmark Facility (CSBF) and the CERN High Energy Accelerator Mixed Field (CHARM) facility in the CERN East Experimental Area

5. Code benchmarking and intercomparison

Oral

The CERN High Energy AcceleRator Mixed Field (CHARM) Facility is situated in the CERN Proton Synchrotron (PS) East Experimental Area. The facility receives a pulsed proton beam from the CERN PS with a beam momentum of 24 GeV/c with 5e11 protons per pulse with a pulse length of 350 ms and with a maximum average beam intensity of 6.7e10 protons per second. The extracted proton beam impacts on a...

15. Radiation protection aspects of Long Shutdown 3 at the CERN LHC experiments: a methodology for residual activation assessments applied to the CMS case study

Tommaso Lorenzon (CERN)

5. Code benchmarking and intercomparison

Oral

The Large Hadron Collider (LHC) at CERN is currently in the early stages of Run 3, i.e. the third operational period of its lifecycle during which the machine will provide particle collisions to the four experiments located along the accelerating ring. Starting from the end of 2025, a three-year Long Shutdown (LS) period, denoted as LS3, will follow. The upgrade work foreseen during this stop...

32. Activation calculations of selected RPV internal components for optimal decommissioning of nuclear power plants

Dr Reuven Rachamin (Helmholtz-Zentrum Dresden-Rossendorf)

5. Code benchmarking and intercomparison

Oral

By the end of this year, all German nuclear power plants (NPPs) will have been shut down. The final shutdown is followed by a post-operational phase in which measures can be carried out to prepare for the NPPs dismantling and decommissioning. One of the important tasks in preparation for the dismantling is to acquire precise knowledge of the specific activities of the reactor pressure vessel...

63. Radiation transport calculations supporting the ISIS muon collimator replacement project

Steven Lilley (STFC)

5. Code benchmarking and intercomparison

Oral

ISIS neutron and muon source, STFC, Rutherford Appleton laboratory Didcot, UK

The ISIS spallation and muon facility uses a proton beam accelerated to 800 MeV in a linac and synchrotron to generate neutrons and, via an intermediate carbon target, muons. The muon intermediate target is located on the extracted proton beam before the neutron spallation target on ISIS target station one. After...

19. Radiation protection studies for new beam dumps at ISOLDE at CERN

Alice Formento (CERN)

22/09/2022, 09:40

3. Induced radioactivity and decommissioning

Oral

ISOLDE is a CERN facility dedicated to the production of radioactive ion beams for applications in atomic physics, nuclear astrophysics, fundamental interactions and life sciences. The 1.4 GeV proton beam from the Proton Synchrotron Booster, with a maximum current of 2 $\mu$A, impinges on a thick target kept at high temperature during irradiation. The generated radionuclides diffuse out of the...
