Abstract An ex-core neutron flux measurement is a crucial system for all common power reactors. It is necessary to monitor the 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 to 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 a graphite moderator or reflector, which is also the case of the TEPLATOR. The TEPLATOR is a solution of a district heating system based on heavy water as a moderator and graphite as a reflector. The 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 the verification of the possible use of the special neutron measuring system placed in the graphite reflector. The Monte Carlo code Serpent was used for the calculations performed in this article.

This paper systematically presents a thorough analysis on the construction of the heating monitoring system in Nanjing General Hospital, China. The monitoring method and strategy of were discussed in detail. Besides, the optimization design of the simple closed loop control system was conducted. Finally, an optimal operation analysis system consisting of the heating host machine, costumer thermal monitoring system, and outside environment monitoring system for the heating room was established. As a result, the heating quality, the heating efficiency, and the relationship with costumer were greatly improved.
