Nuclear Forensics Signatures of Irradiated Fuel

Interactive Content Presentation MORC: Nuclear forensics

Speaker

Dr Francisco Dimayuga (Canadian Nuclear Laboratories)

Description

The international community recognizes that an essential component of a national nuclear forensics capability is the development of a national nuclear forensics library (NNFL). The Canadian Nuclear Laboratories (CNL, formerly Atomic Energy of Canada Ltd.) is contributing towards the development of Canada’s NNFL. Given its unique expertise and access to data, CNL is conducting research into identifying potential forensics signatures of irradiated nuclear fuels used in pressurized heavy-water reactors (PHWR).

As part of the Canadian nuclear industry’s fuel development program, testing of experimental and prototypical fuels has been on-going for decades. This program of fuel testing and performance assessments, including predictive reactor physics code calculations, fuel characterization, and post-irradiation examination (PIE), has accumulated a considerable amount of information on fuels of different types, including uranium and mixed-oxide fuels. The objective of the current research is to determine potential forensics signatures of irradiated PHWR fuels based on isotopic ratios and fission product content. This paper presents correlations of isotopic composition of irradiated fuels obtained from code calculations, validated with actual measured data obtained from PIE.
