Possible implementation of ex-core measurement in TEPLATOR graphite reflector

Popis výsledku v původním jazyce

An ex-core neutron flux measurement is a crucial system for all common power reactors. It is necessary to monitor neutron flux and control the chain reaction therefore the ex-core neutron flux measurement is one of the main safety and control systems. The main advantage of this arrangement of detectors is a fast response on neutron flux change, which determines the reactor power change. Regarding to the new reactor concepts, it is important to deal with improved detection systems suitable for these reactors. Many of the modern reactor concepts are based on the graphite moderator or reflector, which is also case of a TEPLATOR. The TEPLATOR is a solution of district heating system based on heavy water as a moderator and graphite as a reflector. TEPLATOR is designed to use irradiated fuel from the commercial PWR or BWR reactors, which has low to intermediate burnup. This article is focused on verification of possible use of the special neutron measuring system placed in the graphite reflector. The Monte Carlo code Serpent was used for calculations performed in this article.
