Abstract

In this paper, the campaign of RITM-200 reactor was calculated. The duration of the campaign was determined taking the net capacity factor into consideration. The calculated duration concurred with the known data. The neutron parameters were calculated using the effective temperature method. The presence of burnable absorber rods was taken into account. Their effect was considered using the diffusional approach. The iterative computations were used to finally determine the temperature of the neutron gas. At the end, the reactivity curve displaying different effects inside fuel, namely fuel and gadolinium burn-out, the poisoning and slagging was drawn.

Highlights

RITM-200 is the newest reactor for the icebreaking fleet developed by JSC OKBM Afrikantov
The RITM-200 is an integrated PWR type, i.e. it contains the equipment of the first circuit inside the vessel of the reactor
The calculation of the refuelling period was carried out using the effective temperature method

Summary

Introduction

RITM-200 is the newest reactor for the icebreaking fleet developed by JSC OKBM Afrikantov. The RITM-200 is an integrated PWR type, i.e. it contains the equipment of the first circuit inside the vessel of the reactor. One of the features of RITM-200 is the refuelling period, which is up to 7 years. 2. The core description The core contains 199 fuel assemblies. According to [1] the structure of the fuel assembly remained the same as in KLT-40S reactor. Each assembly has 69 fuel rods, 9 burnable type-one absorber rods and 6 type-two absorber rods, and 7 control rods in the center of the fuel assembly (Figure 2).
