Abstract
One of the key elements considered for safe operation of the Nuclear Power Plant is the knowledge possessed by the operators. Plant safety is ensured by inducting well trained operators and engineers having domain knowledge and experience in the related field. Getting acquainted and trained in the simulator environment definitely yields best results when it comes to handling a crisis or an emergency situation by the operators in a plant. High fidelity Full Scope Simulator plays a major role in providing such training platform for imparting comprehensive training on various plant conditions. Modeling and Simulation of Backup Control Room (BCR) is a part of Prototype Fast Breeder Reactor (PFBR) Operator Training Simulator. This paper discusses about various steps involved in Modeling and Simulation of BCR mainly Virtual panel simulation, the associated logic and control simulation, data collection, naming of process variables, interfacing with the associated processes and integration and testing of BCR with Simulator Environment. The need of BCR in Nuclear Power Plant, its location in plant and various features are also included here.
Highlights
In the present scenario, Full Scope Replica Simulator has become a main component of the operator training programme in Nuclear Power Plant
Diversity and redundancy are taken into consideration by the Regulatory Authorities to increase the safety of the reactor like Diverse shutdown systems by incorporating Diverse Control Rod Drive Mechanism, Backup Control Room along with the Main Control Room for easy access in case main control room is inaccessible due to fire or some other reason
Backup Control Room (BCR) is equipped with indicators to monitor neutron flux, control rod position, primary sodium inlet/outlet temperature, primary sodium flow, individual Safety Grade Decay Heat Removal (SGDHR) performance related signals, A Simulation Software is used for development of Prototype Fast Breeder Reactor (PFBR) Operator Training Simulator
Summary
Full Scope Replica Simulator has become a main component of the operator training programme in Nuclear Power Plant. The replicated control room representing the main control room is used for training the operators to increase the skill sets by providing simulator environment for overall monitoring and control of the plant [1,2]. The operators are trained to operate Main Control Room, Handling Control Room and Backup Control Room for various purposes in the plant. Main Control Room is provided to perform overall monitoring and control of the plant and Handling Control Room is used to carry out fuel handling operations. Modeling and Simulation of Backup Control Room is significant as it helps the operators to understand the indicators and controls provided in BCR and get trained on the Diversity and redundancy are taken into consideration by the Regulatory Authorities to increase the safety of the reactor like Diverse shutdown systems by incorporating Diverse Control Rod Drive Mechanism, Backup Control Room along with the Main Control Room for easy access in case main control room is inaccessible due to fire or some other reason.
