Safety in design
Sales Handles: Describes and makes a case for the use of High Temperature Gas-cooled Reactors as better and safer reactors over the currently used Light Water Reactors - Describes the application of the concept of intrinsic continuous process safeguarding in the chemical industry to other fields of society as well, including transportation, farming, the building trade, and leisure - The concept of intrinsic process safeguarding in the chemical industry comprises that the protection of reaction systems is based on their chemical and physical properties and is therefore not endangered by human errors or failures of instrumentation - Includes the description of approximately 70 accidents/incidents - Teaches the reader where applicable to integrate the safety of a design into the design itself - Recommends safe nuclear reactors Market description: Chemical, Civil, Mechanical, Risk, Safety Engineers, Chemists, Physicists, Managers (technical, production, business), Process Safety professionals, HSE professionals Government personnel involved in regulating and overseeing chemical plants and procedures as well as in traffic, storage, production etc Insurers, especially those dealing with catastrophic loss potentials-- Provided by publisher.

Japan's Nuclear Disaster and the Politics of Safety Governance
In Japan's Nuclear Disaster and the
Politics of Safety Governance , Florentine
Koppenborg argues that the regulatory reforms taken up in the wake
of the Fukushima disaster on March 11, 2011, directly and
indirectly raised the costs of nuclear power in Japan. The
Nuclear Regulation Authority resisted capture by the nuclear
industry and fundamentally altered the environment for nuclear
policy implementation. Independent safety regulation changed
state-business relations in the nuclear power domain from
regulatory capture to top-down safety regulation, which raised
technical safety costs for electric utilities. Furthermore, the
safety agency's extended emergency preparedness regulations
expanded the allegorical backyard of NIMBY demonstrations.
Antinuclear protests, mainly lawsuits challenging restarts,
incurred additional social acceptance costs. Increasing costs
undermined pronuclear actors' ability to implement nuclear power
policy and caused a rift inside the \"nuclear village.\" Small
nuclear safety administration reforms were, in fact, game changers
for nuclear power politics in Japan.
Koppenborg's findings contribute to the vibrant conversations
about the rise of independent regulatory agencies, crisis as a
mechanism for change, and the role of nuclear power amid global
interest in decarbonizing our energy supply.

Risk and safety analysis of nuclear systems
\"The book has been developed in conjunction with NERS 462, a course offered every year to seniors and graduate students in the University of Michigan NERS program. The first half of the book covers the principles of risk analysis, the techniques used to develop and update a reliability data base, the reliability of multi-component systems, Markov methods used to analyze the unavailability of systems with repairs, fault trees and event trees used in probabilistic risk assessments (PRAs), and failure modes of systems. All of this material is general enough that it could be used in non-nuclear applications, although there is an emphasis placed on the analysis of nuclear systems. The second half of the book covers the safety analysis of nuclear energy systems, an analysis of major accidents and incidents that occurred in commercial nuclear plants, applications of PRA techniques to the safety analysis of nuclear power plants (focusing on a major PRA study for five nuclear power plants), practical PRA examples, and emerging techniques in the structure of dynamic event trees and fault trees that can provide a more realistic representation of complex sequences of events. The book concludes with a discussion on passive safety features of advanced nuclear energy systems under development and approaches taken for risk-informed regulations for nuclear plants\"--

Transposing an active fault database into a seismic hazard fault model for nuclear facilities – Part 1: Building a database of potentially active faults (BDFA) for metropolitan France
The French Institute for Radiation Protection and Nuclear Safety (IRSN), with the support of the Ministry of Environment, compiled a database (BDFA) to define and characterize known potentially active faults of metropolitan France. The general structure of BDFA is presented in this paper. BDFA reports to date 136 faults and represents a first step toward the implementation of seismic source models that would be used for both deterministic and probabilistic seismic hazard calculations. A robustness index was introduced, highlighting that less than 15 % of the database is controlled by reasonably complete data sets. An example of transposing BDFA into a fault source model for PSHA (probabilistic seismic hazard analysis) calculation is presented for the Upper Rhine Graben (eastern France) and exploited in the companion paper (Chartier et al., 2017, hereafter Part 2) in order to illustrate ongoing challenges for probabilistic fault-based seismic hazard calculations.

Two-dimensional halide perovskite as β-ray scintillator for nuclear radiation monitoring
Ensuring nuclear safety has become of great significance as nuclear power is playing an increasingly important role in supplying worldwide electricity. β-ray monitoring is a crucial method, but commercial organic scintillators for β-ray detection suffer from high temperature failure and irradiation damage. Here, we report a type of β-ray scintillator with good thermotolerance and irradiation hardness based on a two-dimensional halide perovskite. Comprehensive composition engineering and doping are carried out with the rationale elaborated. Consequently, effective β-ray scintillation is obtained, the scintillator shows satisfactory thermal quenching and high decomposition temperature, no functionality decay or hysteresis is observed after an accumulated radiation dose of 10 kGy (dose rate 0.67 kGy h
−1
). Besides, the two-dimensional halide perovskite β-ray scintillator also overcomes the notorious intrinsic water instability, and benefits from low-cost aqueous synthesis along with superior waterproofness, thus paving the way towards practical application.
Efficient radiation monitoring ensures safety in nuclear power, but beta-ray scintillators should be developed for use near a highly radioactive and hot reactor. Here, the authors report a two-dimensional halide perovskite-based beta-ray scintillator with high irradiation hardness and thermotolerance.

Modernized control of a pneumatic facility for short-time NAA at LVR-15 reactor in Řež, Czech Republic
An obsolete control unit of a fast transport (rabbit) system for short-time neutron activation analysis at the LVR-15 experimental reactor at Řež has been replaced. In the new system a PC is used to fully control the rabbit system and the subsequent gamma-ray spectrometry measurement. The modernization resulted in significant simplification of the operator work and improved documentation of the irradiation and spectra acquisition procedures. New nuclear safety features of the rabbit system are also described.
