§ Research

Reactor physics, checked twice.

Thirteen years of Monte Carlo reactor modelling, most of it on the CANDU 6, and a doctoral design for a reactor that burns weapons material. Most of the reactor papers test one code against another.

§1 Topics

What he has worked on.

Research topics
No.Page
01The Multispectrum CANDU ReactorHis doctoral design study: a helium-cooled fast core inside a CANDU thermal core, for burning weapons-grade uranium and plutonium.PhD, RMC 2017
02Monte Carlo verification and validationSix of the seven papers he published between 2013 and 2016 check a code against another code, or against theory, before any design result is used.
03CANDU 6 core modellingFull three-dimensional Monte Carlo models of the Gentilly-2 CANDU 6 core, with every channel and every 37-element bundle, used to map flux, power and burnup and to validate the codes against the industry's own.
04Fuel depletion and burnable absorbersWith the University of West Bohemia's UWB1 team, he was part of the team that benchmarked a fast depletion code on the 37-element CANDU bundle, so burnable-absorber additives can be screened quickly.
05Advanced fuelsUranium nitride in CANDU, thorium for small modular reactors, and a hybrid CANDU core designed to destroy weapons-grade uranium and plutonium.
06Radiation detectorsBefore reactors, his research was on radiation measurement: a statistical model for the efficiency of high-purity germanium detectors, and the characteristics of CZT detectors.

§2 Codes

The codes he works in.

Codes
No.Page
01MCNPHis published MCNP work, from 2013, models coupled reactor cores and a full CANDU 6 core, cross-checked against Serpent and, for burnup, against the industry code WIMS-AECL. He has also taught the code.
02SerpentHe verified the Serpent Monte Carlo code against MCNP and WIMS-AECL on coupled cores and a full CANDU 6 core, then used it to build all six models of the reactor in his doctoral thesis.
03OpenMCHe completed the OECD Nuclear Energy Agency's Introduction to OpenMC in June 2026, adding the open-source Monte Carlo code to a decade of reactor models built and cross-checked in MCNP and Serpent.
