Construction work is underway on a new railhead to support the closure of the redundant nuclear site at Dounreay.
The facility at Georgemas Junction on the far north rail line will enable fuel belonging to the UK to be returned to national stocks where it can be used to generate electricity.
DRS, the train operator developing the site, believes the development of a railhead in Caithness opens up opportunities for non-nuclear cargo to be moved in and out of the area.
Its executives are meeting business and community leaders to explore other potential markets.
Construction of the new multi-million pound facility will be complete by the summer.
Foreign nuclear fuel has been returned from Dounreay over the past decade.
Now, the Nuclear Decommissioning Authority is getting ready to return its fuel to UK stocks.
The first of 44 tonnes of breeder material is due to leave Dounreay later this year and will go via the new railhead to Sellafield.
DRS routinely moves nuclear fuel between Sellafield and UK power stations and the Georgemas railhead will extend its network to Caithness for the first time.
A decision on the remainder of the NDA fuel is due in the spring.
