Abstract
The proposed invention relates to a system and method for estimating the concentration of a nuclear material present in a molten salt, and may estimate the concentration of a nuclear material accurately and with high reliability at low cost using the in temperature change difference that appears as the salt cools among components present in the molten salt in a molten salt reactor.
Claims9
A nuclear material concentration estimation system for non-destructively estimating the concentration of a nuclear material present in a molten salt provided at a bottom, the system comprising:
- a sampling cup for collecting a sample of a molten salt;
- a driving part for driving such that the sampling cup is moved in a vertical direction;
- a control part that controls the driving of the driving part;
- a temperature measuring apparatus that continuously measures a temperature of a sampled molten salt and outputs temperature data;
- and
- a processing part that receives the temperature data showing a gradual cooling change for a predetermined time from the temperature measuring apparatus to estimate a concentration of a nuclear material present in the sampled molten salt.
