Abstract

Pressurized Water Reactor (PWR) power control is carried out by continuously monitoring relevant parameters that depend on operating conditions. It is up to the plant operator to identify when one of these parameters move out of its expected values and perform all the necessary procedures to guarantee that these parameters return to its pre-defined values in a safe way. However, decision-making of which procedures should be done by reactor operators can be subjective, based both on official guidelines and operator expertise. The objective of this work is to implement a real-time autonomous operation system (AOS) that incorporates the knowledge of a human operator for the core power control of a PWR. This AOS is divided in two modules: an expert system controller and a reactivity simulator module. The expert system controller must be able to reproduce all decision processes that would be done by a human operator during their daily activities, while the reactivity simulator reproduces the online behavior of the nuclear plant. The implementation of this AOS is verified and validated against real data of a full operational cycle of a PWR and the presented results show an excellent agreement between AOS simulation and reactor records.

期刊介绍： Progress in Nuclear Energy is an international review journal covering all aspects of nuclear science and engineering. In keeping with the maturity of nuclear power, articles on safety, siting and environmental problems are encouraged, as are those associated with economics and fuel management. However, basic physics and engineering will remain an important aspect of the editorial policy. Articles published are either of a review nature or present new material in more depth. They are aimed at researchers and technically-oriented managers working in the nuclear energy field. Please note the following: 1) PNE seeks high quality research papers which are medium to long in length. Short research papers should be submitted to the journal Annals in Nuclear Energy. 2) PNE reserves the right to reject papers which are based solely on routine application of computer codes used to produce reactor designs or explain existing reactor phenomena. Such papers, although worthy, are best left as laboratory reports whereas Progress in Nuclear Energy seeks papers of originality, which are archival in nature, in the fields of mathematical and experimental nuclear technology, including fission, fusion (blanket physics, radiation damage), safety, materials aspects, economics, etc. 3) Review papers, which may occasionally be invited, are particularly sought by the journal in these fields.
