Dounreay nuclear power plant's operators are being told to take action to prevent a recurrence of a radioactive leak.

The gaseous emission in February triggered an in-house investigation followed by a probe by the Scottish Environment Protection Authority (Sepa).

It found that while the discharge of radioactive dust into the environment was a small fraction of the site's authorised limits, it had put Dounreay Site Restoration Ltd in breach of the regulations.

The radioactive dust vented out of the uranium recovery plant following the failure of a valve while the system was being tested.

DSRL has been issued with a regulatory notice that outlines the steps it is required to take to address the breaches before October 2020.

Earlier this year, the site operators were served with a 'final warning letter' following a probe by Sepa into alleged shortcomings in the system to stop radioactive gases from Dounreay polluting the environment.

A DSRL spokeswoman confirmed it had received a regulatory notice for the incident.

While there had been no breach of its discharge limit, she said it took this issue seriously and said it was and making good progress towards developing an action plan.

A village on the Isle of Skye has been cut off after a landslide amid stormy weather which has battered Scotland.

Gusts of about 60mph and a period of heavy rain hit islands to the west of the country on Tuesday afternoon.

The weather contributed to a "considerable" amount of mud falling from a hillside to cover up to 120m of Kylerhea Road on Skye, cutting off the village of the same name.

Highland Council workers and a digger are at the scene to try and remove the debris and provide access to the people living in the area.

A local authority spokeswoman said: "The entire road is covered and blocked. We have a digger and staff out there working to clear it."

The village is home to a ferry port linking the picturesque island to the mainland.

A BT cable has been impacted by the mudslide, although the council is not aware of any impact on mobile phone coverage.

Meanwhile, another incident on Raasay has seen the "bottom" road near the Raasay outdoor centre closed due to 30m of parapet wall collapsing.

An alternative route is available via the "top" road. Council workers will be unable to gain access to inspect the site and consider repairs until Wednesday.
