Fukushima Exclusion Zone Survival Handbook
Ten years have passed since the 2011 Fukushima nuclear accident in Japan, but its devastating impact has not subsided and may never end, given the radioactivity from the long-term decay period. As one of the most serious nuclear accidents in human history, this is a disaster not only for Japan but …

The Improvised Expert: Performing authority after Fukushima (2011-2018)
… At every turn, those responding to the 2011 Fukushima Daiichi nuclear power plant disaster can be found drawing lines, which determine: where people can live, what they can eat, and who receives additional protections (Potassium Iodide pills, for example). The essential questions of …

An Integrative Approach to Evaluating Radiocesium Contamination in Fukushima Prefecture
… earthquake in Japan led to the meltdown of the Fukushima Daiichi Nuclear Power Plant which released radionuclides into the surrounding regions. Of these radionuclides, cesium-137 (<sup>137</sup>Cs<sup>+</sup>) has been shown to be the most abundant. Research has shown that adsorption of …

Desorption of Non-Exchangeable Radiocesium in soil from Fukushima Prefecture, Japan
<p>The Fukushima Daiichi Nuclear Powerplant was struck by an earthquake and a tsunami resulting in the meltdown of four of the six reactor cores operating at the plant. As a result, nuclear waste was released from the plant, contaminating the soil in the region. Most of the contamination was …

STAMP applied to Fukushima Daiichi nuclear disaster and the safety of nuclear power plants in Japan
… an extremely severe nuclear accident at the Fukushima Daiichi Nuclear Power Plant. This thesis analyzes why the stakeholders could not prevent the Fukushima Daiichi nuclear disaster, and, with regard to the future nuclear safety in Japan, what the potentially hazardous control actions could …

The Politics of Disaster and Their Role in Imagining an Outside. Understanding the Rise of the Post-Fukushima Anti-Nuclear Movements
… and tsunami caused the meltdown of the Fukushima Daiichi nuclear plant, which triggered the largest wave of activism since the 1960s. Based on the author’s fieldwork on the post-Fukushima anti-nuclear movements in Tokyo, this thesis investigates how the disaster impacted people’s sense …

Electron paramagnetic resonance dosimetry and the use of Japanese wild boar tooth enamel as a dosimeter for reconstruction of lifetime external absorbed doses from the Fukushima Exclusion Zone
… external doses to wild boar native to the Fukushima Exclusion Zone using Electron Paramagnetic Resonance Dosimetry. The significance of Japanese wild boar in their ecosystem and their position within the trophic hierarchy make the wild boar a species of particular importance and therefore …

Japan's delayed antinuclear power mobilization after 3.11
The meltdown of Fukushima Daiichi's nuclear plant was one of three disasters that rocked Japan on 11 March 2011, a day often referred to as "3.11." This nuclear accident led to increased attention to and disapproval of nuclear power among the Japanese public. However, despite widespread antinuclear …

Wettability of candidate Accident Tolerant Fuel (ATF) cladding materials in LWR conditions
Since the 2011 Fukushima accident, substantial research has been dedicated to developing accident tolerant fuel (ATF) cladding materials. These analyses have mostly concentrated on the capability of potential ATF materials to withstand runaway steam oxidation and preserve their mechanical strength …

Reactor Core Isolation Cooling Pump Performance in Multiphase Conditions
… caused the operation of three reactors at the Fukushima Daiichi nuclear site to be interrupted. The seismic activity initiated the shutdown of the three reactors and the RCIC system came online in the two reactors equipped with a RCIC system. The RPV must have decay heat removal after shutdown. …

A framework for analyzing nuclear power multiunit accident scenarios and providing accident mitigation and site improvement suggestions
During the Fukushima Daiichi and Daini accidents, the interactions of multiple units at the same site made accident mitigation more difficult compared to single unit sites. The accidents revealed important multiunit risk sources that are not identified by risk assessments for single-unit sites. …

Impact of reactor environment on quenching heat transfer of accident tolerant fuel cladding
… engineering community after the accidents at Fukushima-Daiichi. The primary focus of the ATF program is to identify alternative fuel and cladding technologies that may provide enhanced safety, competitiveness, and economics. The new fuel design must also be compatible with present-day LWR …

MULTI-UNIT ACCIDENT CONTRIBUTIONS TO U.S. NUCLEAR REGULATORY COMMISSION QUANTITATIVE HEALTH OBJECTIVES: A SAFETY GOAL POLICY ANALYSIS USING MODELS FROM STATE-OF-THE-ART REACTOR CONSEQUENCE ANALYSES
… recent operating experience—including the 2011 Fukushima accident—indicate that accidents involving multiple units at a shared site can occur with non-negligible frequency. Yet risk contributions from such scenarios are excluded by policy from safety goal evaluations—even for the nearly 60% of …

Synthesis and oxidation behavior of Cr alloyed uranium borides at high temperatures
Following the nuclear accident at Fukushima Daiichi Power Station in 2011, an urgent need for safer, more economical, and versatile nuclear fuels has arisen. In recent years, uranium boride (as a tetraboride and diboride) has been further investigated as a candidate fuel form for its high thermal …
