New Approach to Reactor Safety ImprovementS

Deliverables

Recommendations for regulators using the integrated hazard framework

This deliverable will be a synthetic document providing recommendations for the regulators and describing best practice and identified deficiencies in the current methodologies for hazard assessment see task 15 for details

Use of E-BEPU for evaluation of Design Extension Conditions

This deliverable will present the applicability of E-BEPU methodology for DEC analysis and possible benefits it might bring for future NPPs' design (results from sub-task 3.4.3).

Improved methodologies for extreme earthquake hazard assessment

This deliverable will present the implementation of the conditional spectra approach (so-called risk-targeted hazard), as proposed in sub-task 1.2.4.

Methodologies to constrain uncertainties in the components’ modelling (causes and consequences)

This deliverable will present the adaptation of advanced uncertainty assessment approaches to identify and priorize most influential sources of uncertainty in the parameters (external threats, etc.) and NPP elements' modelling, so that uncertainty on modelling results can be constrained before integration within the BBN (cf. sub-task 3.2.2).

Review of state-of-the art for hazard and multi-hazard characterisation

This deliverable will present the extensive review of existing multi-hazard approaches and procedures for natural hazard assessment with respect to nuclear hazard and safety, as proposed in task1.1.

Methods to incorporate human factors within a multi-hazard approach

This deliverable will present the method developed to enable integration of human aspects into fragility functions and to investigate their impact on them (cf. task 2.4).

Definition of hazard-induced damage states and development of state-specific APETs for demonstration purposes

This deliverable will provide a map of the key decisions identified in task 5.2, to be made during the implementation of EOP/EDMG/SAMG in response to the considered hazard damage state into the logic of corresponding state-specific APET, developed based on the experience and knowledge from the Level-2 PSA studies (cf. task 5.3).

Methodology to account for soil-structure interactions in the fragility assessment

This deliverable will first present a new simplified modelling technique for seismic SSI with a reduced computation time, hence useful within the framework of PSA process. Second, the proposed model will be compared to existing tools (e.g. SASSI) on well-known NPP case studies, e.g. derived from international benchmarks (see sub-task 2.2.2 for details).

Description of a meta-modelling strategy for probabilistic analyses

This deliverable will present some model reduction strategies applicable for assessing the impact of external hazards (e.g. earthquakes, flooding) on NPPs from a probabilistic perspective (outputs from sub-task 4.2.1).

Use of E-BEPU for evaluation of Defence-in-Depth

This deliverable will present the systematic application of E-BEPU methodology for Defence-in-Depth implementation (results from sub-task 3.4.2).

Development of single and secondary effect hazard assessment methodologies including uncertainty quantification and comparison

This deliverable will provide methods to analyse extreme hazards using multi-varied statistics and to account for secondary hazards associated with each NPP component separately using physical approaches. On the other hand, it will present a stochastic approach to scenario development, allowing characterization of the hazard curve to integrate all possible uncertainty, temporal and spatial combinations for Design Basis Events (see task 1.3 for details).

Production of an integrated hazard framework for combined hazard scenarios for Safety Assessment

This deliverable presents the systematic framework for combination of hazard scenarios in order to provide an integration of the various single and cascade internalexternal hazards that are possible at a site The multihazard and multirisk methodology of the FP7 MATRIX project will be adapted and further developed so that the risk metric refers to the performance goals for the NPPs and in order to use novel approaches for sensitivity analysis for complex systems see details in task 14

Improved methodologies for tsunami hazard assessment

This deliverable will present the use and implications of fast GPU computations for PHA on one hand, and on the other hand, the general probabilistic hazard assessment approach to be developed for earthquake-triggered tsunamis (see sub-task 1.2.1 for details).

Use of the E-BEPU method for SAMG

This deliverable will present the application of the E-BEPU method for the development and V&V of SAMG on the LB LOCA reclassification (results of sub-task 5.4.7).

Methodology to derive vector-based fragility functions I: theoretical aspects

This deliverable will present the general methodology proposed in task 2.3, to design and check elaborate fragility models with respect to multiple intensity measures (i.e. vector-valued), thus harmonizing the response of the NPP SSC to multi-hazard solicitations.

Project presentation brochure

The project brochure will present the main information on the NARSIS project: aims and main expected outcomes, consortium, ...

Improvements of flexible approaches and procedures relying on expert-based information

This deliverable will present the proposed improvement of the current practices in terms of flexible approaches / procedures and uncertainty propagation in relation with expert-based information and knowledge modelling, using recent advanced procedures and tools (cf. task 3.3 for details).

Flooding impact on industrial facilities via advanced numerical modelling

This deliverable will present the results of SPH simulations of a realistic coastal NPP platform for selected flooding event scenarios (tsunami, storm). These results will be analyzed with respect to the requirements of nuclear engineering (see details in sub-task 1.2.3).

Risk integration methods for high risk industries

This deliverable will present a review and comparison of risk integration methods from high risk industries (e.g. aviation, chemical and nuclear industries), with particular emphasis on methods able to incorporate low probability events, multi-hazards, and integration of human, social/organizational and technical aspects (cf. task 3.1). It will also review the deterministic & probabilistic methods for identification of latent weaknesses in complex industrial facilities. Hence, this deliverable merges the contents of former deliverables D3.1 (due on M12) and D3.6 (initially due on M18, but now suppressed).

Constraining the uncertainties in the components modelling (causes and consequences) – Application to Station Blackout event

The development of the Bayesian Network model (task 3.2) requires a specific analysis to identify, classify and analyze the main sources of uncertainties that affect the progression and consequences for the major event of Station Blackout (SBO). This deliverable will present this dedicated analysis in addition to the existing deliverable D3.3, more related to the development of advanced methodologies for fulfilling this objective.

Improved methodologies for extreme weather and flooding hazard assessment

This deliverable will first report on proposed methods and related uncertainties, to address combination of phenomena in the framework of flooding hazard curves assessment. The probabilistic assessment of failures for some geotechnical safety structures by external hydraulic effects will also be addressed in this deliverable (see details in sub-task 1.2.2).

Communication and Dissemination Plan report

Communication and Dissemination Plan report of the project.

Development of risk sub-networks for technical and social/organizational aspects

This deliverable will first present the probabilistic description of fault and consequence for technical aspects, compatible with a non-parametric dynamic BBN approach. Then, it will present the works related to the implementation of the risk sub-network for social/organizational and human aspects (cf. sub-task 3.2.1).
