Small Modular Reactors An Analysis of Factors Related to Siting and Licensing in Washington State Prepared for: Washington State Energy Facility Site Evaluation Council January 2016 Executive Summary This report investigates the potential for developing Appendix A to this report provides a status update nuclear power generation in the state of Washington, for many of the agencies, companies and research focusing on one of the advanced nuclear reactor organizations who are involved in activities related design technologies currently in development: Small to SMR development and related nuclear power Modular Reactors (SMRs). SMRs are defined by the development. This provides the reader with an US Department of Energy (USDOE) and others in understanding of current SMR technology and the industry as nuclear power plant “modules” of development, much of which would apply if an 300 megawatts or less. Their concept includes offsite applicant proposes an SMR in Washington in the future. manufacturing, self-contained fuel, power generation For example, industry groups and agencies such as and cooling, multiple module operation, and passive USDOE have recommended a number of regulatory core failure protection that requires no action to changes related to SMR licensing. The NRC is considering ensure core integrity in the case of an accident. rule changes in response to those recommendations. This report looks at a range of potentially suitable Finally, although many different SMR technologies locations for such a facility in Washington by applying are being examined around the world, the United selected site selection criteria on a statewide basis. It States has 4-5 different designs in contention. The also considers the locations of past and present power USDOE selected two of these designs as candidates plant sites, including past nuclear sites. The report for funding and development support. For this study, discusses the many water supply options available we developed a generic SMR design model that is an to an applicant, and their constraints, and the lower amalgam of the two finalists (NuScale and mPower). water use options available for SMRs. It also describes We used this model as the basis for our analysis of the typical process likely to be followed to permit such potential locations for SMRs in Washington. Since a facility in Washington; makes recommendations for the USDOE selection, the mPower project has slowed streamlining this permitting, mostly using existing down its rate of development and lost its USDOE rules and regulations; and suggests studies and/ funding, leaving the NuScale design as the apparent or activities that the State can implement, track, or leader for the time being, although the Tennessee investigate in the future.

Our model SMR is a combination of the two and State could better coordinate with that process, this report does not favor any SMR design. The status recognizing that the NRC siting process is likely to be of these projects is also discussed in Appendix A. the critical path because it is longer than the State’s process. The report also discusses the connected roles that the Federal Emergency Management Agency (FEMA) and the US Environmental Protection Agency (USEPA) have with the NRC licensing process, as well as the role of Washington’s Energy Facility Site Evaluation Council (EFSEC) and other agencies.

It does not State might consider, and the timing of those steps, in address public acceptance as a siting criteria, nor does preparation for the next Site Certification Agreement it evaluate the implications of Initiative 394 (passed (SCA) to EFSEC for a nuclear power plant. The report in 1981), which requires a public vote to approve the discusses when the State may want to take actions issuance of bonds to support the construction of any if there was a desire to attract SMRs, attract their major public energy facility. Instead, we considered manufacturing, or pass legislative incentives. Such other siting factors, and discussed potential facility recommendations are entirely dependent on the costs and schedules without defining the sources State’s direction and goals. Some other states have of funding. taken steps to address these goals already. The report is organized into the following chapters: SMR development has the potential for significant improvements in nuclear plant siting associated with ▪ Chapter 1 – Background, scope, and approach cost, safety, permitting schedule, generation flexibility, ▪ Chapter 2 – Small reactor history leading to and site requirements. It also has the potential for today’s technology significant carbon-free baseload generation. Public ▪ Chapter 3 – The assumptions that went into and agency concerns are still likely, related to waste the Model SMR used to evaluate site suitability disposal, fuel transport, and nuclear power, but in Chapter 4 the potential for advances in safety and licensing processes offered by SMRs have generated interest in Chapter 4 – An overview of suitable locations for ▪ Washington, the United States, and around the world. SMRs in Washington, recognizing that a nuclear plant siting study would need to incorporate site- specific factors and 1-2 years of study ▪ Chapter 5 – A discussion of the major permit requirements including considerable details about the NRC and related processes, so the State can evaluate opportunities for involvement ▪ Chapter 6 – Recommendations for streamlining and improving the permit process, and recommendations for further actions the State can consider to stay informed and be involved in the SMR siting and development process ES-2 Golder Associates Table of Contents Executive Summary ....................................................................................
