Identification of BPM for Removing Molecular Sieves from the Argon Suite

Objective:

To identify the client's Best Practicable Means (BPM) for the removal of redundant molecular sieves.

Added value to client:

Determination of the BPM to remove the most contaminated part of the facility to reduce the residual hazard during subsequent decommissioning.

Activity:

RM Consultants Ltd (RMC) facilitated a BPM study to cover the client’s options for the removal of four vessels containing tritium-contaminated molecular sieve material from the Argon Suite in a facility. They are part of the Gas Clean-Up System (GCUS) housed in an old, long redundant, Gas Clean Up Plant. The study was carried out in accordance with the Company's guidance for the identification and assessment of BPM.

Options for the disconnection and removal of the molecular sieves from the GCUS and packaging the molecular sieves for transport to another building were assessed.

The BPM was selected and the choice justified in terms of its clear advantages. The Management System arrangements required to undertake the BPM option were identified and a Forward Action Plan recommended to the client.
