1. 1. Uncertainty Analysis : Severe Accident Scenario at a Nordic Nuclear Power Plant

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Josefin Hedly; Mikaela De Young; [2023]
   Keywords : Nuclear power plant; microdata analysis; Random Forest; k-Nearest Neighbor; SVM;

   Abstract : Nuclear Power Plants (NPP) undergo fault and sensitivity analysis with scenario modelling to predict catastrophic events, specifically releases of Cesium 137 (Cs-137). The purpose of this thesis is to find which of 108 input-features from Modular Accident Analysis Program (MAAP)simulation code are important, when there is large release of Cs-137 emissions.

   Abstract : Kärnkraftsolyckan i Tjernobyl 1986 spred radioaktivt nedfall över Europa och Sverige som kom att tas upp i ekosystemet av växter, djur och människor. I Sverige innebar det att älg (Alces alces), rådjur (Capreolus capreolus) och ren (Rangifer tarandus) fick förhöjda halter av Cesium-137, 137Cs, som i sin tur togs upp av de människor som åt av köttet.
