摘要： A computer-implemented simulation method, based on a sub-channel approach of predicting local mass fluxes of vapour and liquid in coolant water anywhere along fuel rods within any fuel assembly mechanical design of a Boiling Water Reactor, (BWR), for given steady-state or transient boundary conditions, the sub-channel approach is based on the solution of mass, momentum and energy conservation equations for the vapour phase and the liquid phase, the liquid phase is represented by more than one field variable, and is specifically represented by three fields, with the vapour phase as a fourth field, consisting of droplets, a liquid base film, and disturbance waves, the method comprises solving individual mass, momentum and energy conservation equations, for said four fields, and solving the necessary closure relations describing the transfer of mass between the said fields, completed by models describing local phenomena including one or many of base film dryout, clad temperature increase, or drop entrainment from waves, wherein the method further comprises:
- simulating steady-state or transient boundary conditions, including any postulated scenarios relevant to BWR operation with respect to the potential appearance and rewetting of dry patches between waves, associated dry time and clad temperature increase, and
- analysing predefined parameters of said disturbance waves and liquid base film, including wave velocity and frequency, and base film thickness.

摘要： The present invention provides nuclear power plant intelligent technical specification method and system. The nuclear power plant intelligent technical specification method includes the steps of: obtaining a predetermined operating signal and a device state of a nuclear power plant by means of a nuclear power plant KNS system (S101); determining an operating condition of the nuclear power plant according to the device state (S102); determining whether to trigger a predetermined event according to the operating signal, the operating condition and a preset threshold (S103); upon determining to trigger a predetermined event, activating the predetermined event and triggering processing measures and supervision requirements corresponding to the event, and simultaneously starting a timer to remind an operator to complete the processing measures required by specification within a specified time (S104). The present nuclear power plant intelligent technical specification method and system may intuitively reflect safety indicators of the nuclear power plant, and help an operator to handle the event quickly, so that the safety of the nuclear power plant is improved, the economy and the availability of the nuclear power unit are improved, and the market economy value is high.
