Fission Multiplicity Distribution Sampling in MCNP6 Criticality Calculations
… explicit fission neutron multiplicity models in MCNP6. To determine the effect of sampling fission multiplicity probability distributions during criticality (KCODE) calculations, it was necessary to modify MCNP6 to allow for the use of neutron fission multiplicity models during criticality …

Developing a fresh core neutronic model at 300K for a VVER-1000 reactor type using MCNP6
… code, Monte Carlo N-Particle, version 6 (MCNP6). This research study is based on a VVER type of pressurized water reactor (PWR), which is of Russian design. The neutronics model is done at 300 K, assuming the use of fresh fuel. Major core operational parameters including the 𝑘𝑒𝑓𝑓 , power …

Discrete ordinates CT organ dose simulator (DOCTORS)
… DOCTORS code was benchmarked against MCNP6 and found to have good qualitative agreement using both a water phantom and a realistic patient phantom. DOCTORS was also found to be much faster than MCNP6; MCNP takes hours to compute flux profiles that take less than a minute using …

Nuclear warhead monitoring : a study of photon emissions from fission neutron interactions with high explosives as a tool in arms control verification
… experiment using the radiation transport code MCNP6 to help understand the observed results. The experimental and simulation data suggest that correlated backgrounds from neutron interactions with environmental materials dominate the signal. This finding helped provide a basis for understanding …

Design and characterization of a strong positron source at the MSTR beam port
… its intensity. Monte Carlo simulations using the MCNP6 code were used to model the positron production and moderation processes at the MSTR beam port. The thermal neutron flux at the beam port was determined experimentally and used in the source definition of the radiation transport simulations. …

A Preclinical Study of Radiation-Induced Lung to xicity When Irradiating In A Strong Magnetic Field
<p>The purpose of this work was to evaluate the effect of a strong, transverse magnetic field on the severity of radiation-induced lung damage in mice. This data can be used to support the safe clinical implementation of MRI-guided radiation therapy systems.</p> <p>Monte Carlo simulations and EBT3 …
