Research
Review of HEPA filter ageing
Eliott Lindsay, Consultant
Engineer, Frazer-Nash Consultancies
In 2020, ONR commissioned
Frazer-Nash to undertake a research review of HEPA filter ageing on behalf of
the nuclear industry. This talk will summarise the findings and
recommendations from this review, including:
·
Current understanding of
HEPA filter ageing mechanisms and the basis of UK HEPA filter Relevant Good
Practice (RGP)
·
Advances in HEPA filter
strength and ageing management, including the role of high strength HEPA
filters
