Zero power critical

<h2 id="role-of-zero-power-reactors-in-nuclear-safety">Role of Zero Power Reactors in Nuclear Safety</h2> <p>The <a href="/facts/Nuclear_Energy_Agency/sa86Knja">Nuclear Energy Agency</a> (NEA) has documented a shift in the usage of zero power reactors (ZPRs). Previously used for engineering prototypes, these reactors now serve in validating <a href="/facts/Nuclear_data/S0kMC1Jb">nuclear data</a> and simulation codes. This shift has occurred against a backdrop of a global decrease in ZPR facilities, affecting the field's experimental capabilities.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a> </p><p>The NEA workshop "The Demise of Zero Power Reactors: From Concern to Action," held on June 22–23, 2023, at the <a href="/facts/Institut_de_radioprotection_et_de_s%C3%BBret%C3%A9_nucl%C3%A9aire/X8mbdrU7">Institut de Radioprotection et de Sûreté Nucléaire</a> in <a href="/facts/France/CxIeIKM3">France</a>, addressed these changes. This event brought together international experts to discuss new approaches for <a href="/facts/Reactor_physics/lgJG9pJB">reactor physics</a> validation and <a href="/facts/Data_preservation/5Wfe9pU2">data preservation</a>, considering the reduced number of ZPR facilities. A report from the NEA's Working Party on Scientific Issues and Uncertainty Analysis of Reactor Systems Task Force on Zero Power Reactors, due in early 2024, will summarize these discussions. It is expected to offer guidance on ZPRs' future role in <a href="/facts/Nuclear_safety_and_security/TtudaSPh">nuclear safety</a> and regulation.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> </p> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>"The demise of zero power reactors: From concern to action".
