Data Library

A method of on-line monitoring for commercial PWRs using eigenfunctions has been proposed in prevenient works. In this method, the eigenfunctions combine with the detector readings are used to reconstruct the real reactor power distribution. But it is very difficult to choose the eigenfunctions because the condition of the reactor is much complex. Therefore, some improvements on this method are studied in this paper. A number of representational conditions according to the reactor fuel management are picked up to create a data library of different eigenfunctions. On the monitoring process, the computer will judge that which represen6tational conditions most close to the real reactor condition and choose the eigenfunctions which will be used to reconstruct the reactor core power distribution combine with the detector readings. A reactor of Qinshan Nuclear Power Corporation is studied here as an example. The detector readings are from the simulator. The numerical result shows that this method can reconstruct the reactor power distribution with high speed (about 0.03 seconds for each step) and high accuracy (the relative errors are lower than 3% mostly).

Based on the measured parameters, including core power distribution, system pressure, inlet coolant temperature and flow, departure from nucleate boiling ratio (DNBR) can be calculated on-line. This paper presents a strategy to develop the DNBR online monitoring and protection system for PWR nuclear power plant (NPP). The main functions are to provide core DNBR status to operator and to replace the delta-T protection in conventional PWR NPPs. The system structure consists of two different levels respectively for monitoring and protection. There are four cabinets in each level to insure the reliability. DNBR on-line algorithm is on the basis of a modified single channel thermal-hydraulic model. A computer program was developed and verified through comparison with the sub-channel code.
