Deliverables

Project Quality Plan (opens in new window)

Task 9.1 Project coordination and quality management (M1-48), led by EDF. Participants: EDF: EDF, as project coordinator will ensure the project is running smoothly and will act as the communication facilitator of the consortium to form and engage in a fruitful collaborative work. This task will comprise consortium coordination and facilitation, monitoring the project progress, having a validation process for deliverables, organising project meetings. A comprehensive Project Quality Plan and Project Management Plan will be presented in M3. A travel provision is foreseen for the partners’ attendance to regular project plenary meetings (when physical meetings are necessary, otherwise, online meetings with a lower carbon footprint will be preferred). Partners will actively contribute to concrete actions and using of tools to systematically integrate the gender perspective in all WPs. EDF will also manage the advisory board and will follow its recommendations expressed during the meetings between the advisory board and the ExCom.

SMR-compatible waste management systems (opens in new window)

D1.2 SMR-compatible waste management systems (availability, demonstration, practices): for low- and intermediate-level waste (LILW) similar type of coolant purification devices (e.g. coolant filters, resin), waste processing systems and waste package procedures would be benchmarked as those of commercial LW nuclear power plants (NPPs). Regarding high-level waste (HLW), the spent fuel would be considered transportable, stored and disposed of without additional processing. In addition, identifying LILW streams based on large NPP experience (scaling down) would be another objective of the deliverable in terms of how the management of these waste streams works, what are the requirements. Expected differences between commercial and LW SMR waste compositions (e.g. actinide content) should be evaluated.

Specifications of LDR-50 fresh core at BOC conditions (opens in new window)

The main objective of this work package is to perform a neutron physical analysis of two boron-free SMR-core designs, namely the PRACTIC and LDR-50-lite, developed by CEA and VTT, respectively. To meet this objective, both static, depletion, and transient analysis of both core designs will be performed using different computational tools including industry-like methods based on diffusion, and academic high-fidelity approaches including transport (SP3, SN) and Monte Carlo methods applied stand-alone or coupled with thermal hydraulic codes (1D system and quasi-3D subchannel TH). To achieve these objectives, the following tasks are considered:Task 7.1 Definition of the neutron physical characteristics of the SMR-core for BOC and EOC (M1-6), led by CEA. Participants: CEA, VTT, EDF, FRAMATOME: This task describes the main characteristics of the SMR-cores. The respective deliverables are the basis for the follow-up tasks and collect all data needed to set up calculations from lattice to core models. Full specifications of the fresh core loadings including operation conditions, material properties, geometry, etc. for both core designs are provided in the respective deliverables. Two subtasks are included:Subtask 7.1.2: Specifications of the LDR-50-lite fresh core, led by VTT. Participants: VTT.

Identify and review the methodologies currently used for passive system reliability evaluation (opens in new window)

There are several currently known and used methodologies/approaches in the world to assess the reliability of passive systems. In this task, ENEA will coordinate a detailed independent process of a bibliographical review and comparison of these proven methodologies (such as REPAS/RMPS/APSRA/ROAAM+). The main goal is to identify and compare the possible advantages or limitations of existing approaches. Based on the performed study and on proposed relevant criteria, 2 currently used approaches/methods will be selected by participants for its application in the following WP4 steps. Depending on the specific methods chosen, the content of the next tasks may differ slightly.

Project management plan (opens in new window)

Task 9.2 Financial management and administrative coordination (M1-48), led by EDF. Participants: EDF: EDF will provide administrative/financial/legal support including preparation of consortium operating procedures; support in the management of the GA and the CA, preparation of meetings/conferences agendas, venues and minutes, preparation of templates for reporting. EDF, as coordinator will be responsible for the overall budget management, its timely allocation and distribution. With contributions from all partners, the coordinator will maintain financial records, coordinate cost submissions, and oversee EC payments and partner shares.

Literature review on cybersecurity regulations, guidelines and standards for different modes of operations (opens in new window)

Identify characteristics and challenges concerning the above-mentioned specificities in terms of cyber security that could impact safety of LW-SMR: this objective will be addressed through a literature review including sources like regulations, standards, IAEA guidelines and national cyber security agencies in addition to scientific literature. Furthermore, we will also study threats/vulnerabilities in addition to reported cyber incidents within the nuclear domain that would provide foundation for building scenarios.

EPZ calculation for a multi-unit SMR site (opens in new window)

The task objective is to explore the main issues on co-location of SMR modules at a nuclear site. The respective issues to be covered in this are related to determining emergency planning zone (EPZ) depending on number of SMR modules
