1. 1. Validering av Ecolego för modellering i enlighet med PSA nivå 3 : Beräkning av markdeposition av radionuklider vid fiktiv svår härdskada vid Forsmarks kärnkraftverk

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

   Författare :Olivia Winestedt; [2022]
   Nyckelord :PSA nivå 3; Probabilistisk säkerhetsanalys; Ecolego; GPM;

   Sammanfattning : The scope of this project is to investigate if the software Ecolego is suitable for creating models in accordance with level 3 PSA, with the goal of creating a model calculating the possible outcomes for the radiological impact at 20 km distance resulting from a fictional severe nuclear accident at the Forsmark Nuclear Power Plant. This report aims to answer the questions “What is the concentration on the ground (kBq/m2), at a distance of 20 km, 30 days and 10 years after the fictional severe nuclear accident, with and without filtered venting” and “Is Ecolego a suitable software for level 3 PSA models?” The source term for the fictional severe nuclear accident is made to resemble the actual source term from the Fukushima Daiichi accident including the radionuclides Cs-134, Cs-136, Cs-137, I-131, I-132, I-133 and Te-132.

3. 2. The picture has changed, how about the frame? Media framing of nuclear energy in Japan before and after the Fukushima nuclear disaster

   Master-uppsats, Lunds universitet/Centrum för öst- och sydöstasienstudier

   Författare :Gabriela-Cosmina Gherghe; [2021]
   Nyckelord :Media framing; Framing analysis; Thematic analysis; Fukushima; Nuclear power; Japan; Social Sciences;

   Sammanfattning : On March 11, 2011, a magnitude 9.0 earthquake followed by a 15-meter tsunami and a nuclear accident at Fukushima Daiichi changed the normal course of events in Japan and far beyond it. Among other consequences, the events triggered a sudden increase in domestic and international media coverage. LÄS MER

4. 3. Evaluation of Epistemic Uncertainties in Probabilistic Risk Assessments : Philosophical Review of Epistemic Uncertainties in Probabilistic Risk Assessment Models Applied to Nuclear Power Plants - Fukushima Daiichi Accident as a Case Study

   Magister-uppsats, KTH/Filosofi

   Författare :Omed A. Rawandi; [2020]
   Nyckelord :Probabilistic Risk Assessment; PRA; Probabilistic Safety Assessment; PSA; Uncertainty; Epistemic Uncertainty;

   Sammanfattning : Safety and risk assessment are key priorities for nuclear power plants. Probabilistic risk assessment (PRA) is a method for quantitative evaluation of accident risk, in particular severe nuclear core damage and the associated release of radioactive materials into the environment.

5. 4. Case Study: Future Scenarios of Japan’s Energy Supply System in the Aftermath of the Fukushima Daiichi Nuclear Power Disaster

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Wen-Tien Wang; [2020]
   Nyckelord :Sustainable Development; Energy Supply System Analysis; Times Series Analysis; Japan; Kaya Identity; Forecasting.;

   Sammanfattning : Nine years have passed since the Fukushima Daiichi nuclear disaster (FDND). The Japanese government has been facing the issue of striking a balance among economy, environment, and social opinions for its energy transition policy. LÄS MER

7. 5. Fukushima Daiichi as a heterotopia : Dark tourism in dystopian places

   Master-uppsats, Lunds universitet/Centrum för öst- och sydöstasienstudier

   Författare :Klas Bergman; [2018]
   Nyckelord :Fukushima; Heterotopia; Tourism; Dark tourism; Digital and visual methods; Japan; Social Sciences;

   Sammanfattning : This thesis deals with tourism to Fukushima. Specifically, it examines how traditional tourism and dark tourism shape the identity of Fukushima. LÄS MER
