Analysis for Siting and Sizing of a Small Modular Reactor — A Case Study in Canada

摘要

This paper analyzes the problem of Siting and Sizing of a Small Modular Reactor (SMR) in a weakly connected section of an existing electrical grid in north-central part of Canada. Although various sizes are available, the limited capacity of an SMR to respond to the sudden changes in operating conditions --a concern specific to SMR and other nuclear plants -- confines the prospect of having plant size suitable for the economic operation. A study is carried out to determine the size of SMR suitable for the system at various hosting locations and the relative impact of the size on the economic operation. The prospect of having a Pumped hydroelectric energy storage (PHES) along with an SMR is also investigated, and the optimum size of SMR with and without PHES is obtained.
