VERAShift – VERAShift is the hybrid deterministic-Monte Carlo ex-core radiation transport interface package serving as the application programming interface (API) for integrating in-core depletion and thermal-hydraulics calculations performed with MPACT and CTF with ex-core calculations performed with Shift . Its initial development began in 2015 and it is mainly used to perform ex-core transport calculations for light water reactors in the VERA code suite. These calculations include vessel ﬂuence, detector response including during reactor startup, and concrete ﬂuence.
VERAShift is also used as a verification and/or validation tool by utilizing its Monte Carlo eigenvalue solution capability.
