Calculations have been performed for steady state and postulated transients in the VVRK reactor at the Institute of Nuclear Physics (INP) in Alatau, Kazakhstan. These calculations have been performed at the request of staff of the INP who have performed similar calculations. Calculations were performed for the fresh low-enriched uranium (LEU) core and for four subsequent cores as beryllium is added as a radial reflector to maintain criticality during the first 15 cycles of operation. The calculations include neutronics parameters, steady-state power and temperature distributions, and response to transients. These calculations have been performed independently from those being performed by INP and serve as one step in the verification process.
