S3R

Almost all boiling water reactors and many pressurized water reactors use a core monitoring system in the plant control room. These core monitor systems combine measured data and physics calculations monitor the compliance of fuel thermal limits according to the plant’s Technical Specification requirements. For a variety of reasons, these systems are frequently not available in the simulated control room, or are available only via a simplified emulation. This paper presents a product which allows rigorous core monitoring to be present in the control room. Further, this paper discusses the additional instructional capabilities offered by the usage of software of this nature.

Almost all boiling water reactors (BWRs) and many pressurized water reactors (PWRs) use a core monitoring system in the plant control room. These core monitor systems combine measured data and physics calculations to provide operations assistance information. For a variety of reasons, these systems are frequently not available in the simulated control room, or are available only via a simplified emulation. This paper presents a product which allows rigorous core monitoring to be present in the control room. Further, this paper discusses the additional instructional capabilities offered by the usage of this software.

Cycle specific core performance on a training simulator is a significant motivation for a simulator core model upgrade. The accuracy of the numerical method used in the core model is the primary consideration in the evaluation of the core model. The characteristics of an “engineering grade” core model and the benefits of using such a core model are described. A standard benchmark data set is then analyzed with the engineering grade core model S3R. Further, the effects of using more approximate models are quantified.
