Copeland MP Trudy Harrison also met Dr Clark.
She said: “I urged Greg Clark to work with our community to develop a plan that delivers for west Cumbria.
“As the centre of nuclear excellence, it is essential that his department recognises our skills and capability to ensure support for Sellafield and Moorside.
“It is pretty simple to me; there is a national need for more electricity.
“The skills we have around Sellafield in design, commissioning, operating a safe nuclear plant and decommissioning using the most advanced technology are world class, but we lack routes to market.
“We are not tapping into the £250bn global decommissioning economy, or the £1.2 trillion nuclear new build economy.”
