In the process of periodical test cycle extension demonstration work of a nuclear power plant, for test items with different test modes and cycles, in order to reduce unnecessary demonstration workload, a cycle control strategy can be formulated so as to discriminate the test items needing to implement cycle extension demonstration in advance and determine a target cycle (a test cycle to be extended), wherein the basic principle for formulating the cycle control strategy comprises the following four points:
(1) for the test items performed daily, the extended period is not considered. Of course, for some special test projects, the test period can be prolonged appropriately according to the feedback of the experience of other nuclear power plants.
(2) For a test project which can be converted into daily execution, performing conversion to daily execution feasibility analysis and demonstration generally, and converting into daily execution after the demonstration is passed; or the operation experience of the similar unit can be directly used for reference to be converted into the daily execution without the feasibility analysis and demonstration of the conversion into the daily execution.
(3) The target period can be shortened and prolonged, if the material changing period is changed into flexible operation, the target period is not suitable to be prolonged by more than 6 months of the original period according to the conversion of natural days; if the period of material changing is prolonged to 24 months, the period is not suitable to exceed 12 months of the original period according to the conversion of natural days.
Based on the basic principle, the periodic control strategy of the periodic test period of the test item can be determined directly according to the type of the test item.
Specifically, if the types of the test items are: and determining the periodic control strategy of the periodic test period of the test items as follows: the cycle is not extended.
If the type of the test item is: and if the test period is the test items of 'n refueling periods' and 'n cycles', determining the period control strategy of the periodic test period of the test items as follows: and carrying out periodic control on the periodic test period of the test item by adopting a preset method.
In some embodiments, the formulating the period control strategy of the test item according to the type of the test item and the adjustment mode of the refueling period comprises: if the type of the test item is: a first test item (a test period is a test item that is performed daily), then the period control strategy for determining a periodic test period for the test item is: the period is not prolonged; if the type of the test item is: and the second test item (the test item with the test period of 'n refueling periods' and 'n cycles') determines the period control strategy of the periodic test period of the test item as follows: and (4) making a period control strategy of the test item by adopting a preset method based on the adjustment mode of the refueling period.
Based on the adjustment mode of the refueling period, the period control strategy for formulating the test items by adopting a preset method can comprise the following steps: a general cycle control strategy and a specific cycle control strategy.
In some embodiments, a general cycle control strategy may be formulated based on the following method:
judging whether the periodic test of the test item meets a first condition or not; if so, the period control strategy of the test item is as follows: prolonging the periodic test period of the test item according to the target period; if not, judging whether the periodic test of the test item meets a second condition; if the periodic test of the test item meets the second condition, the periodic control strategy of the test item is as follows: changing the regular test period of the test item into daily execution; or carrying out periodic control according to the operation experience of the similar units; and if the periodic test of the test item does not meet the second condition, making a periodic control strategy of the test item based on the adjustment mode of the refueling period.

Further, if the periodic test of the test item meets the third condition, a periodic control strategy of the test item is formulated based on the adjustment mode of the refueling period. Wherein the third condition: the test item is a second test item and does not satisfy the first condition and the second condition.
Specifically, if the test item can only be executed during the refueling overhaul period and belongs to the equipment function re-identification test performed to meet the refueling overhaul requirement, the test period is extended to the target period. The test cycle settings for these test items are therefore independent of the fuel cycle length and are dependent on whether a refuel overhaul is performed. If the test item can be executed during both the refueling overhaul period and the power operation period, the test period control can be changed to daily execution. If the test item is not a test item which can be executed during both the refueling overhaul period and the power operation period and is not a device function re-identification test performed to meet the refueling overhaul requirement, the test period of the test item is controlled according to the type of the regular test period of the test item.

If the adjustment mode of the material changing period is a second sub-adjustment mode, the period control strategy of the test item is as follows: a second control strategy. In addition to the above-described general cycle control strategy, the test items in which the adjustment mode of the refueling cycle is the second sub-adjustment mode also have a specific cycle control strategy, that is, the second control strategy.
If the adjustment mode of the material changing period is a third sub-adjustment mode, the period control strategy of the test item is as follows: a third control strategy. In addition to the above-described general cycle control strategy, the test items in which the adjustment mode of the refueling cycle is the third sub-adjustment mode also have a specific cycle control strategy, that is, a third control strategy.
If the adjustment mode of the material changing period is a fourth sub-adjustment mode, the period control strategy of the test item is as follows: and a fourth control strategy. In addition to the above-described general cycle control strategy, the test items in which the adjustment mode of the refueling cycle is the fourth sub-adjustment mode also have a specific cycle control strategy, that is, the fourth control strategy.
Optionally, the first control strategy includes:
if the test item is 1C12The test period of the test item is adjusted to be less than or equal to 24 months of flexible operation test period control; if the test item is 2C12、4C12、5C12、7C12、8C12、10C12The test items of (1) are the test items ofThe test period was adjusted as follows: carrying out flexible operation test period control according to the natural day of the original period of the test item; if the test item is 3C12、6C12、9C12The test item is firstly demonstrated by a preset prolonged period, and after the demonstration is passed, the preset prolonged period is added on the basis of the original period of the test item to carry out flexible operation period control; wherein C represents a refueling cycle.
