Waste Packaging and Storage

Porvair Filtration Group actively supports the nuclear waste treatment and storage industry. As processes are developed to deal with legacy wastes and legislation is introduced to define storage conditions, we are at the forefront of developing novel solutions to meet increasingly complex filtration problems through our extensive research programme. 

Vent Breathers for Nuclear Casks / Containers and Spent Fuel Transportation Casks 

Using a range of metallic filter media in a variety of metal types, Porvair is able to supply waste package breathers that are precisely tailored to the individual needs of any application.

Available with defined separation efficiencies, gas diffusion and flow/ΔP characteristics.

Specially designed vent breathers and permeation devices supplied to nuclear storage users include but not limited to:
• HEPA (THE) grade shielded vent breathers for spent fuel drying and storage
• WIPP compliant TrU waste package vent breathers
• 500 litre drum breathers
• 3m3 box breathers
Designed to meet global specifications’.

WIPP Filters Vents

The TRUPACT-II Safety Analysis Report (SAR) outlines the specific requirements for particulate containment efficiency, pressure drop, and hydrogen diffusivity in the packaging, transport, and disposal of transuranic radioactive waste (TRU) at the Waste Isolation Pilot Plant (WIPP) in New Mexico.

Furthermore, on-drum testing confirms their adherence to U.S Federal shipping standards under DOT Specification 7A.

The TRUvent™ filter vent has been validated and approved as meeting all WIPP operational requirements.
