Nuclear Engineering, Safety & Fuel

12 tools for reactor engineering: kinetics, shielding, fuel, source terms, reactor standards and nuclear risk.

Neutron Transport (2-D Monte Carlo)Draw a shielding geometry out of real materials and watch neutrons cross it.Prototype · Stages: Basic engineering, Detailed engineering · Benchmark reportEN UA DE NL FR ES PL
Xenon-135 TransientCoupled iodine-135 / xenon-135 dynamics after shutdown. Xenon overshoots as I-135 keeps decaying while burnup stops — the “xenon pit” that can lock out restart (reactor dead time).Benchmark tested · 38/38 · Stages: Basic engineering, Operation & maintenance · Benchmark reportEN UA DE NL FR ES PL
Point Reactor KineticsPoint kinetics with six delayed-neutron groups. Insert a step reactivity to see the prompt jump, the stable period and the inhour curve — and the prompt-critical boundary at one dollar that operation must never cross.Benchmark tested · 74/74 · Stages: Basic engineering, Operation & maintenance · Benchmark reportEN UA DE NL FR ES PL
Small Modular Reactor ScreeningSmall modular reactors are a catalogue of about a hundred designs of which perhaps fifteen could actually be ordered, so the matching is the easy part and the honesty is everything.Prototype · Stages: Concept · Benchmark reportEN UA DE NL FR ES PL
Reactor Live StandA point-kinetics reactor that runs continuously in wall time instead of producing a finished record.Benchmark tested · 33/33 · Stages: Operation & maintenance · Benchmark reportEN UA DE NL FR ES PL
Spent Fuel Decay Heat & Source TermsDecay heat, gamma and neutron emission of irradiated fuel from one second to a million years after shutdown.Prototype · Stages: Basic engineering, Detailed engineering, Operation & maintenance · Benchmark reportEN UA DE NL FR ES PL
Reactor Core Scoping StudioSize a bare cylindrical core of thirteen reactor lines, read its k-effective, cycle length, discharge burnup, feedback coefficients and fuel cost from lattice data computed with OpenMC and ENDF/B-VIII.0.Prototype · Stages: Concept, Basic engineering · Benchmark reportEN UA DE NL FR ES PL
Probability Budget — reactor failure gamePlay the failure library: pick a tool, strike a reactor schematic, and see whether the barriers of that revision hold and what the sequence costs against the screening threshold.PrototypeEN NL
RPV Embrittlement & PTS ScreeningScreening of reactor-vessel embrittlement against 10 CFR 50.61 or the alternate 10 CFR 50.61a path, with traceable inputs, margins and missing-data gates.Benchmark tested · 265/265 · Stages: Operation & maintenance · Benchmark reportEN UA DE NL FR ES PL
Probabilistic Risk ExplorerBuild linked fault trees and routed event trees, calculate exact Top Event probability, truncated or full minimal cut sets, importance, sensitivity and uncertainty.Benchmark tested · 18/18 · Stages: Basic engineering, Detailed engineering, Operation & maintenance · Benchmark reportEN UA DE NL FR ES PL
Safety Improvement PrioritiserEnumerates feasible safety-improvement portfolios under budget and schedule constraints, preserves CDF/LERF overlap uncertainty, and exposes the Pareto set without collapsing engineering consequences into one score.Benchmark tested · 232/232 · Stages: Operation & maintenance · Benchmark reportEN UA DE NL FR ES PL
Nuclear Standards Orientation AidMaps the normative landscape of a nuclear project by facility type, lifecycle stage and jurisdiction: which documents belong to the field, what work has to be done, and which bodies will ask for it.Benchmark tested · 13/13 · Stages: Concept, Basic engineering · Benchmark reportEN UA DE NL FR ES PL
