[Document Title] [EHNUR WP 4] ADVANCED NUCLEAR POWER PLANT CONCEPTS AND TIMETABLES FOR THEIR COMMERCIAL DEPLOYMENT Steven C. Sholly1 VIENNA, June 2013 1 Institute of Safety/Security and Risk Sciences, University of Natural Resources and Life Sciences Copyright Vienna, June 2013 Media owner and editor: University of Natural Resources and Life Sciences Vienna, Department of Water, Atmosphere and Environment, Institute of Safety and Risk Sciences, Borkowskigasse 4, 1190 Wien, Austria URL: http://www.risk.boku.ac.at ReportWP4 – Advanced Nuclear Power Plant Concepts and Timetables EHNUR EXECUTIVE SUMMARY Most currently operating nuclear power plants are Generation II reactors (except for a few remaining Generation I units and a few Generation III units). Generation III and Generation III+ nuclear power plant concepts are widely recognized to be significant improvements over Generation II reactor designs. Both Generation III designs (standardized designs safer than Generation II) and Generation III+ designs (standardized designs safer than Generation II and with the expectation of greater economy of scale) are available for immediate deployment. The absolute minimum schedule for a Generation III or III+ nuclear power plant project is 10 years from feasibility study to completion of startup testing. Such a schedule is only achievable by: (a) an experienced utility, (b) with the reactor sited at an existing nuclear power plant site, and (c) with a design for which first-of-a-kind engineering (FOAKE) is complete. Under other circumstances (e.g. a utility new to nuclear generation, a greenfield site, a utility in a country without significant nuclear infrastructure, a nuclear power plant design where FOAKE has not yet been accomplished), the schedule would extend from fifteen to seventeen years and perhaps more. Within the 2030 time horizon of the ENHUR project, there are a number of advanced reactor designs available for immediate deployment that could be licensed, constructed, and placed in operation in time contribute to electricity generation by the year 2030. These designs are: • Eight advanced pressurized water reactors (PWRs) – AP1000, APR-1400, APWR, ATMEA1, EPR, VVER-1000 AES-91, VVER-1000 AES-92, and VVER-1200/491. As of June 2013, two units of VVER- 1000 AES 91 were in operation, and two units of VVER-1000 AES 92 were nearing operation. The first units of AP1000 and EPR were also nearing operation. Units of the AP1000, APR-1400, EPR, and VVER-1200/491 designs were under construction in June 2013. • Five boiling water reactors (BWRs) – GE-Hitachi ABWR, ESBWR, Toshiba EU-ABWR, KERENA, and Toshiba US-ABWR. As of June 2013, there were four ABWRs in operation, and two ABWRs were under construction. • Two pressurized heavy water reactors (PHWRs) – ACR-1000 and CANDU EC-6. There have been no orders as of June 2013 for either of these designs. • Three small modular reactors – CAREM-25, KLT-40S, and SMART, all PWRs. As of June 2013, there was one unit of CAREM-25 and two reactors (on one barge) of KLT-40S under construction. • One Generation IV Very High Temperature Reactor (HTR-PM). As of June 2013, there were two HTR-PM modules under construction. There are also five remaining Generation II reactor designs that were still (as of June 2013) under construction and for which plans exist to construct additional plants of these designs): BN-800 fast breeder reactor, the CNP-300 and CNP-600 PWRs, the CPR-1000 PWR, the PHWR-700, and the OPR- 1000 PWR. It is possible, although not very likely in view of the nominal duration of 17 years and the minimum to maximum range of 13-33 years for a nuclear power plant construction project (from feasibility study to commercial operation), that a few additional reactor designs with near-term deployment possibilities (2015-2020) could be finished in time to contribute to electricity generation by the year 2030. Plants with such designs would have to be ordered by 2015 -2020 in order to be able to be completed and online by 2030 using the absolute minimum schedule constraints (experienced utility, 3/134 ReportWP4 – Advanced Nuclear Power Plant Concepts and Timetables EHNUR existing nuclear power plant site, standard design with FOAKE complete, and design certification by the regulatory authority). There are an increasing number of advanced reactor designs that may become available in time to generate electricity after 2030. Generation IV design concepts are still being studied, and except for a few prototype units, Generation IV reactors are not expected to begin operation until 2040 or thereafter. Nuclear fusion, although promising as a source of electricity, has no chance of producing electricity before 2030, and only a small chance of producing electricity on a commercial scale before 2050. 4/134 ReportWP4 – Advanced Nuclear Power Plant Concepts and Timetables EHNUR CONTENT METHODOLOGY 9 Limitations 9 1 BACKGROUND 10 1.1 Status of operating units and units under construction 10 1.2 Development of the nuclear industry over the past 40 years 17 1.3 The stages in the design of a nuclear power plant 20 1.4 How long does it take for a nuclear power plant to be constructed and placed in operation? 23 2 ADVANCED REACTORS AND ISSUES RELATED THERETO 28 2.1 What are advanced reactors? 28 2.2 To which generation of reactors do the following designs correctly belong? 30 2.3 Which advanced reactor designs appear to have been abandoned, and for what reasons? 34 2.4 Nuclear power plant efficiency 34 2.5 Deterministic safety assessment (safety analysis) and probabilistic safety assessment (psa) 35 2.6 Cautionary discussion regarding advanced reactor cost estimates (the difference between over-night and all-in estimates) 39 3 HOW DO ADVANCED REACTORS COMPARE WITH GENERATION II NUCLEAR POWER PLANT DESIGNS? 43 4 HOW DOES THE DURATION OF SITING, AND CONSTRUCTON AFFECT THE POTENTIAL OF ADVANCED REACTORS TO BE DEPLOYED IN TIME TO START PRODUCING ELECTRICITY BEFORE 2030? 48 5 WHAT ADVANCED REACTOR DESIGNS COULD BE DEPLOYED IN TIME IN ORDER TO PRODUCE ELECTRICITY BEFORE 2030 – SOURCES OF INFORMATION AND GENERAL CONSIDERATIONS 51 6 WHAT ADVANCED REACTOR DESIGNS ARE AVAILABLE FOR NEAR-TERM DEPLOYMENT (BEFORE 2020)? 56 7 BASED ON CURRENT (MID-2013) INFORMATION, WHAT ADVANCED REACTOR DESIGNS COULD BECOME AVAILABLE FOR DEPLOYMENT AFTER 2020 IN ORDER TO PRODUCE ELECTRICITY BEFORE 2050? 57 8 WHAT ARE THE POTENTIAL ADVANTAGES AND DETRIMENTS OF SMALL MODULAR REACTORS? 58 9 WHAT IS THE DEPLOYMENT HORIZON FOR GENERATION IV ADVANCED REACTOR DESIGN CONCEPTS, AND WHAT ARE THE POTENTIAL ADVANTAGES AND DETRIMENTS OF SUCH CONCEPTS?59 10 WHAT IS THE DEPLOYMENT HORIZON FOR NUCLEAR FUSION TECHNOLOGY ON A COMMERCIAL SCALE? 62 5/134 ReportWP4 – Advanced Nuclear Power Plant Concepts and Timetables EHNUR 11 SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS 64 REFERENCES 66 ANNEX 1 – ACRONYMS AND INITIALISMS 96 ANNEX 2 – DEFINITIONS OF TERMS 103 ANNEX 3 – PSA RESULTS FOR GENERATION III & III+ ADVANCED REACTORS AND GENERATION II REACTORS 108 ANNEX 4 – TABLES 110 6/134 ReportWP4 – Advanced Nuclear Power Plant Concepts and Timetables EHNUR LIST OF FIGURES FIGURE 1: PWR REACTOR PRESSURE VESSEL. .......................................................................................................... 13 FIGURE 2: PRESSURIZED WATER REACTOR CONCEPT. ............................................................................................. 13 FIGURE 3: BOILING WATER REACTOR CONCEPT. ..................................................................................................... 14 FIGURE 4: GAS-COOLED REACTOR CONCEPTS. ........................................................................................................ 14 FIGURE 5: PHWR REACTOR CONCEPT. ..................................................................................................................... 15 FIGURE 6: VVER REACTOR CONCEPT– VVER PRIMARY SYSTEM. ................................................................................... 15 FIGURE 7: RBMK REACTOR CONCEPT. ..................................................................................................................... 16 FIGURE 8: FAST REACTOR CONCEPT.

  • Russia's Nuclear Security Policy
    Innovative approaches to peace and security from the Stanley Foundation POLICYANALYSISBRIEF THE STANLEY FOUNDATION | MAY 2015 Russia’s Nuclear Security Policy: Priorities and Potential Areas for Cooperation The crisis over Ukraine has led to a drastic reduction in regular official Russian-US contacts in most areas, including those where it is in the two countries’ mutual national security interests to work together. Bilateral cooperation on nuclear nonproliferation and nuclear security has been among the affected areas. The United States has suspended contacts with Russia in the framework of the G-8 and in the Russian-US Bilateral Presidential Commission’s Nuclear Energy and Nuclear Security Working Group. Implementation of the September 2013 agreement on Cooperation in Nuclear- and Energy- Related Scientific Research and Development (R&D Agreement), which Anton Khlopkov prioritizes joint efforts on nuclear nonproliferation and nuclear security, has also been put on hold, and exchanges between nuclear scientists of the two Author countries have been frozen. In turn, Russia has decided not to take part in Anton Khlopkov1 is director of the preparations for the 2016 Nuclear Security Summit. Moscow also notified Moscow-based Center for Energy and Washington that most of the joint nuclear security projects in Russia would Security Studies and editor in chief of the not be extended beyond December 31, 2014. journal Nuclear Club.

    小型飛翔体／海外 ［Format 2］ Technical Catalog Category Airborne contamination sensor Title Depth Evaluation of Entrained Products (DEEP) Proposed by Create Technologies Ltd & Costain Group PLC １．DEEP is a sensor analysis software for analysing contamination. DEEP can distinguish between surface contamination and internal / absorbed contamination. The software measures contamination depth by analysing distortions in the gamma spectrum. The method can be applied to data gathered using any spectrometer. Because DEEP provides a means of discriminating surface contamination from other radiation sources, DEEP can be used to provide an estimate of surface contamination without physical sampling. DEEP is a real-time method which enables the user to generate a large number of rapid contamination assessments- this data is complementary to physical samples, providing a sound basis for extrapolation from point samples. It also helps identify anomalies enabling targeted sampling startegies. DEEP is compatible with small airborne spectrometer/ processor combinations, such as that proposed by the ARM-U project – please refer to the ARM-U proposal for more details of the air vehicle. Figure 1: DEEP system core components are small, light, low power and can be integrated via USB, serial or Ethernet interfaces. 小型飛翔体／海外 Figure 2: DEEP prototype software ２．Past experience (plants in Japan, overseas plant, applications in other industries, etc) Create technologies is a specialist R&D firm with a focus on imaging and sensing in the nuclear industry.

    Ikata Nuclear Power Plant on the island of Shikoku, Japan. Owned and operated by the Shikoku Electric Power Company. This PWR has no cooling tower but cools by direct exchange with the ocean. Equipment for current nuclear plant projects The nuclear industry is undergoing a globalisation process. Companies like Westinghouse, GE, Areva and MHI are increasingly selling their expertise beyond their national borders; technology transfers and tie-ups are more frequent; plans are being laid to harness nuclear energy for desalinisation projects and - an industry first - for the manufacture of steel. Focus on Nuclear Power Generation surveys the scene, casting a particularly close eye on the role of suppliers in the slow but steady resurgence on the nuclear power industry. By James Chater he much talked about “nuclear still small. No wonder, then, that the 2007 the Finnish steel company announced renaissance” is happening, but progress is construction of nuclear power stations is put it had teamed up with Sweden's Boliden, Tslow.

Test and/or demonstration reactors were built and operated in the United States, France, Japan, United Kingdom, Russia, India, Germany, and China—totaling about 20 reactors with 400 operating years to date. These previous reactors and current projects are summarized in Table 4.H.1.2 Currently operating test reactors include BOR-60 (Russia), Fast Breeder Test Reactor (FBTR) (India), and China Experimental Fast Reactor (CEFR) (China). The Russian BN-600 demonstration reactor has been operating as a power reactor since 1980.

Vorsitzender: Prof. Phaedon-Stelios Koutsourelakis, PhD Prüfer der Dissertation: 1. Prof. Rafael Macián-Juan, PhD 2. Prof. Dr. Jean-Baptiste Thomas Die Dissertation wurde am 08.05.2018 bei der Technischen Universität München eingereicht und durch die Fakultät für Maschinenwesen am 01.11.2018 angenommen. ABSTRACT This research work investigates the design and optimization of the high conversion small modular reactor (HCSMR) core. The HCSMR has a thermal output of 600 MW for 200 MW electrical. It is an integrated PWR with a tightened fuel assembly lattice. The rod-to-rod pitch is 1.15 cm in a hexagonal fuel assembly geometry. As a result the moderation ratio (1.0) is reduced compared to large PWRs (around 2.0) and the HCSMR has an improved ability to convert 238U into 239Pu and use plutonium isotopes more efficiently. The core is loaded with MOX fuel. The HCSMR concept finds its roots both in large high conversion light water reactors and small modular reactor (SMR) concepts. The reduced core size results in an increased neutron leakage rate compared to large cores. This intrinsically supports the core behavior in voided situations. The necessity to introduce fertile fuel materials in the core to keep negative void coefficients is reduced, contributing to the HCSMR safety and limited core heterogeneity.
