2019.jul.08-11EU: Horizon2020-Euratom call on LWR-SMRs NFRP-2018-3: Research on the safety of Light Water Small Modular Reactors

SMRs: “interesting safety features” “residual heat removal and size of containment structure” “compliance with the EU Safety Directive may significantly vary depending on safety options of

proposed design”, hence “need to be further investigated”

2

“investigate improved safety features of Light Water SMRs” “provide fundamental technical specifications” (to be tested by safety regulators) “propose a methodology for the performance of these tests” (including experimental validation

of essential items + effects on SMR licensing process, considering potential fields of application) other items: “safety of refuelling”, “of spent fuel management”, “decommissioning” 5% Edu&Training

establish a “baseline for testing LW-SMRs compliance with EU Safety Directive and for SMR’s licensing process”

preparation for a “robust science-based recommendations to decision makers regarding nuclear safety of Light Water SMRs at EU level”

“The challenge”

“The scope”

“The impact”

2019.jul.08-11ELSMOR project(selected & funded by Euratom)

Main objectives:

Collection, analysis, and dissemination of information on potential and challenges of SMRs to EU stakeholders (public, decision makers, regulators)

Development of high level methods to assess the safety of LW-SMRs

Improvement of the EU experimental R&D infrastructure to assist in the evaluation of novel safety features of LW-SMRs

Improvement of EU nuclear safety analysis codes to demonstrate the capability to assess the safety of LW-SMRs

2019.jul.08-11ELSMOR project(selected & funded by Euratom)

Approach: adopt F-SMR design as a case study / “test bed” for safety

methodology development & applicationExpected result: safety case methodology developed by ELSMOR to assist in

establishing a baseline for SMR's licensing process in EU (licensed and operating Light Water SMR demonstrators in EU in 10- 15 y)

science-based state-of-the-art recommendations to decision makers regarding nuclear safety of Light Water SMRs at EU level

Kick-off meeting on Sept.4-5 at VTT
