Nuclear industry proficiency test exercises

Supporting the nuclear industry

The nuclear industry proficiency test exercises (PTE) is a regular scheme during which a 200 L drum of ‘simulated’ waste is produced by NPL. This waste drum contains inactive low-density material with vials of resin, in initially undisclosed locations spiked with gamma-emitting radionuclides of known activity. The drum is sent to participating labs, who then measure the drum using a non-destructive method. A single report is produced summarising all the results and data analysis.

Upcoming exercise (2021)

Participation for the 2021 exercise is open until mid-May 2021. Please register your interest via the ‘contact us’ section below.

Past exercises (2019)

The last exercise was the 2019 nuclear industry PTE which concluded in 2020. For a copy of the report please make a request via the ‘contact us’ section below.

Other exercises

There is interest in using a similar approach to produce a 1m3 ‘bag’ PTE in addition to or as an alternative to the drum. If you are interested in either of these exercises, please contact us.

For questions, queries and comments relating to the nuclear industry PTE scheme please contact us.
