Metrology for New Generation Nuclear Power Plants–MetroFission

Abstract

This EMRP (European Metrology Research Programme) project, MetroFission, has been looking at solving metrological problems related to a new generation of nuclear power plants. The proposed Generation IV power plants are designed to run safely, make efficient use of natural resources, minimize the waste and maintain proliferation resistance. In order to reach these goals, the reactor operation involves higher temperatures, high-energy neutron fluence, different types of fuel where the minor actinides are included etc. In this overview of the multidisciplinary project, which has 12 partners in 10 countries, the work described has focused on improved temperature measurements, investigation of thermal properties of advanced materials, determination of new and relevant nuclear data and development of measurement techniques for radionuclides suitable for Generation IV power plants.

Nuclear instrumentation and measurement: a review based on the ANIMMA conferences

“…High temperature measurements in severe conditions are required [87,170,188] and there is a need for temperature reference sensors for the next generations of NPP [84]. The Practical Acoustic Thermometry sensor developed by The National Physical Laboratory [176] uses acoustic guided waves propagating in straight or/and bended metallic tubes (filled with argon, for example), the speed of sound being temperature dependent.…”

Lessons Learned From Nuclear Decay Data Measurements in the European Metrology Research Programme ‘Metro Fission’

“…OLLOWING the EURAMET EMRP Energy call of 2009, the research project "Metrology for new generation nuclear power plants" or "MetroFission" was funded for a 3 years period. The project started in September, 2010 and was run by a European consortium of 12 partners [1]. It aimed at answering several metrological problems related to the development of the proposed Generation IV nuclear reactors design.…”
