Burn-Up Automatic Measure System of 10MW High Temperature Gas Cooling Reactor

In order to ensure the high availability of pebble bed type high temperature gas cooling reactor,it is the critical process to measure the burn-up level for each ball in accurate and efficient way.The automatic operation of burn-up measurement of 10MW high temperature reactor（HTR-10） is unimplemented yet.Ac-cording to the design theory of FCA system and operation characters of fuel circulation procedure,the original manual flow of burn-up level measurement methods is improved and burnup can be automatically measured.The field operation results have proved the reliability in performance and the accuracy in logic.It can effec-tively avoid the accidents caused by error operation.
