Subracks go nuclear

Verotec Ltdvisit website


Heysham Nuclear Power station runs four AGR reactors on its site in the North West of the UK, and Verotec was recently approached by Beran Instruments, a certified F4N (Fit for Nuclear) company, to provide custom 19” subracks to house upgraded power supplies on the site.

Verotec says that it was selected as the hardware supplier because of its extensive standard product portfolio and in-house design and manufacturing capability, coupled with a field-proven installed base. Strong and rugged design together with a wide range of standard sizes and a choice of accessories were other factors that secured the contract.

The custom installation at Heysham consists of matched pairs of special 4U/84HP/360mm deep KM6-II subracks with vented EMC covers and custom machined rear panels, and the complete system comprises various widths of plug-in units to house the modules with machined and digitally printed front panels. One of the two subracks is fitted with a custom metal backing plate to support H15 DIN connectors; both versions are fully EMC screened, and are fitted with a special interlock bar to the front of the subracks to prevent unauthorised removal of the plug-in modules.
