FISPACT-II
FISPACT II is an advanced nuclear simulation software. It provides predictive, spectral and temporal simulation methods for neutron and charged-particle interactions using comprehensive nuclear data libraries.
Overview
FISPACT-II is an enhanced multiphysics, inventory and source-term code system developed by the UK Atomic Energy Authority at Culham. It provides advanced predictive, spectral and temporal simulation methods for neutron and charged-particle interactions using comprehensive nuclear data.
FISPACT II has applications in:
- magnetic and inertial confinement fusion
- advanced fission Generation IV and beyond
- other advanced energy and fuel systems
- high energy and accelerator physics
- medical applications, including isotope production
- earth exploration and astrophysics
- homeland security
- materials science
- nuclear maintenance and decommissioning
- … and more
FISPACT-II is capable of various analysis techniques including:
- activation analysis
- transmutation calculations
- depletion and burn-up simulations
- decay modelling
- source definition
- full inventories
- displacement per atom (dpa) calculations
- Kerma calculations
- Primary damage (PKA) spectra
- gas / radionuclide production simulations
Key benefits
- nuclear data agnostic – you can pick the best nuclear data library for your neutron, proton or other calculations
- Application Programming Interface (API) allows easy and safe linkage to other codes
- validated – used on ITER, DEMO and STEP for fusion, and on fission power plants (e.g. characterising fuel rods, shut down dose calculations)
- pathways analysis (where does key nuclei come from) can help with material engineering
- can identify radioactive emission of a given sample
- can predict decay heat and gamma dose
Software details
FISPACT II supports users in:
- full processing of ENDF-6 nuclear data with complete TENDL data and covariances
- self-shielding factors calculation
- temperature dependence modelling
- thin / thick target yields
- robust pathway analysis
- Monte-Carlo sensitivity and uncertainty quantification
- covariance data propagation
- for a given neutron flux, activation/transmutation of fusion materials/metals/alloys can be calculated
- radiation shielding calculations can be completed to help design new power plants
- displacements per atom (DPA) can be calculated to quantify radiation damage in materials from nuclear collisions and reactions
- shut down dose calculations for fission and fusion power plants to help design safe operations and shielding needs
- waste calculations for the running of future fusion and fission power plants
- medical radio-isotope sector – understanding design, target needs and safe operation
- ability for FISPACT-II to model waste processing using irradiation
- waste assessment for nuclear materials prior to decommissioning
