The ball passing counter transmits the ball passing number to the DCS system, and the operation and fuel management personnel can carry out the evaluation work of the fuel element circulation through data analysis. The ball passing counter has a ball passing counting function, but has no logic judging and alarming functions, the counter is wrongly timed, the main control DCS interface has no corresponding alarming display, the number of fuel elements of the ball bed type high temperature gas cooled reactor is large, most of the time is carried out every day, an operator can hardly find the counting error of the ball passing counter in time, the counting error ball passing counter can continuously count and accumulate on the basis of the error, if the running time is overlong, the logic error on the number of the fuel elements can be difficult to analyze, and great difficulty is brought to nuclear fuel management and nuclear material control work.

and if the sum of the fourth readings is not equal to the second reading, determining that the pending counter is an anomaly counter.
FIG. 4 is a schematic diagram of a logic chain shown in accordance with an exemplary embodiment. As shown in fig. 4, in a part of the logic chain, connection nodes 403, 408, 409, 410, 411, and counters 401, 402, 404, 405, 406, 407, 412, 413, 414, 415 are included. For a connecting node 403, 401, 402 to be its upstream counter, a first reading is taken from the counter 401, 402, a second reading is taken from the counter 404, 405, 406, 407, so the target logical relationship is that the sum of the readings of 401, 402 = the sum of the readings of 404, 405, 406, 407, and if the sum of the first readings is not equal to the sum of the second readings, the counter 401, 402, 404, 405, 406, 407 is determined to be the pending counter. In the logic chain, for a connection node 408, 404 being its upstream counter, 412 being its downstream counter, and 408 being the downstream connection node of 404, a fourth reading of 412 may be taken, a determination may be made as to whether the fourth reading of 412 is equal to the second reading of 404, since connection node 408 has only one upstream counter and one downstream counter, if the fourth reading of 412 is equal to the second reading of 404, it is indicated that the reading of 404 is normal and 404 is not an anomaly counter. For connection node 409, 405 is its upstream counter, 413 is its downstream counter, and 409 is the downstream connection node of 405, a fourth reading of 413 is taken, found to be unequal to a second reading of 405, indicating that the reading of 405 is abnormal, 405 is the anomaly counter.
After the abnormal counter is determined, the abnormal counter is marked as red in the system, the correct reading is calculated and then fed back to the operator, and the counter reading is modified after accounting.
By the method, the counter with the false meter can be timely and accurately found and modified, and the readings of all the counters can be ensured to truly reflect the running state of the reactor core.
Meanwhile, a counter logic judgment table produced every day in software can be used as an operation record of the high-temperature gas cooled reactor nuclear power station to be stored, and the historical operation state of the unit can be checked at any time.
