Among other things, the committee will discuss what measurements are still missing, such as fuel type, burn-up history or storage time, and whether and how these measurements can be made.<\/p>\n<p>An accurate determination of the decay power for longterm storage, and the determination of its uncertainty, is important both for extended interim storage and for subsequent disposal. Material temperatures such as those of the cladding tubes or the outer wall of the cask can be better predicted with more accurate data on decay power. In this project, BGZ is directly involved in the evaluation of current measurement data and in the recommendation and planning of new experiments to complete and extend the existing data on decay power.<\/p>\n<\/div><\/section>\n<section  class='av_textblock_section av-mhj4f8tm-64ce56d656267790211205961d5fc152 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><p>The model of the cask was created in the first phase and the calculations carried out according to the benchmark description (see Figure 11). The results were sent to the organisers for evaluation and publication. The second phase will involve more detailed study and quantification of the uncertainties in the modelling and their effects on the calculated cladding tube temperatures. The results are expected by 2024 and will be published in a summary report. BGZ will contribute results to the benchmark in addition to the results arrived at in association with GNS and WTI.<\/p>\n<\/div><\/section>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_one_full-cd2f474e3bba50187b6ed141031f97f7\">\n#top .flex_column.av-av_one_full-cd2f474e3bba50187b6ed141031f97f7{\nmargin-top:0px;\nmargin-bottom:0px;\n}\n.responsive #top #wrap_all .flex_column.av-av_one_full-cd2f474e3bba50187b6ed141031f97f7{\nmargin-top:0px;\nmargin-bottom:0px;\n}\n<\/style>\n<div  class='flex_column av-av_one_full-cd2f474e3bba50187b6ed141031f97f7 av_one_full  avia-builder-el-6  el_after_av_textblock  el_before_av_hr  first flex_column_div  column-top-margin'     ><p>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_hr-fb8f8e4fa21dcdb365b9430aeb7c21a4\">\n#top .hr.av-av_hr-fb8f8e4fa21dcdb365b9430aeb7c21a4{\nmargin-top:30px;\nmargin-bottom:30px;\n}\n.hr.av-av_hr-fb8f8e4fa21dcdb365b9430aeb7c21a4 .hr-inner{\nwidth:100px;\nborder-color:#0d57a0;\n}\n<\/style>\n<div  class='hr av-av_hr-fb8f8e4fa21dcdb365b9430aeb7c21a4 hr-custom  avia-builder-el-7  el_before_av_textblock  avia-builder-el-first  hr-left hr-icon-no'><span class='hr-inner inner-border-av-border-fat'><span class=\"hr-inner-style\"><\/span><\/span><\/div><br \/>\n<section  class='av_textblock_section av-mm0svcbb-4f7c49088946700424e3b6ac409e4acc '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><h2 class=\"anleser\">Publications<\/h2>\n<\/div><\/section><br \/>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-av_hr-7a1a1df713b91246e12e7c5d2b3f0a33\">\n#top .hr.hr-invisible.av-av_hr-7a1a1df713b91246e12e7c5d2b3f0a33{\nheight:5px;\n}\n<\/style>\n<div  class='hr av-av_hr-7a1a1df713b91246e12e7c5d2b3f0a33 hr-invisible  avia-builder-el-9  el_after_av_textblock  el_before_av_textblock '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div><br \/>\n<section  class='av_textblock_section av-mm0svouj-7baadbec2819dd05ec0583ce24b8e916 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><ul>\n<li><a href=\"https:\/\/www.epri.com\/research\/products\/000000003002026549\"><strong>Used Fuel and High-Level Waste Management Program: Spent Fuel Decay Heat Measurements at Clab: Description of Decay Heat Measurements from 2003 &#8211; 2021 Under EPRI-SKB Collaboration<\/strong><\/a>, H.
