The Nuclear Decommissioning Authority (NDA) is overseeing the dismantling of several UK sites, including Dounreay near Thurso in Caithness.
Representatives from the NDA and oil and gas experts have met in Aberdeen to share information.
One of the areas covered was the decommissioning of oil pipelines.
The event was held at Aberdeen's Oil and Gas Technology Centre.
The NDA said it was actively looking outside its sector for technologies to use in the decommissioning of nuclear power sites.
Among major Scottish oil and gas installations being decommissioned are the Buchan Alpha floating production vessel off Aberdeen, and the Beatrice complex in the Moray Firth.

Author Philip Pullman remembered her as "a warm and generous human being", while Tracy Chevalier said she was "a graceful, elegant writer and person."
Dunmore won the first Orange Prize for women's fiction in 1996 for her novel A Spell of Winter.
Publisher Penguin Random House said it was "devastated by the loss of one of our best-loved authors".
Bloodaxe Books, which published Dunmore's first poetry collection, The Apple Fall in 1983, said it was "immensely saddened" by her passing.
Born in the Yorkshire town of Beverley in 1952, Dunmore also wrote books for children, short stories and translations.
Her most recent novel, Birdcage Walk, was published in March.
Dunmore was diagnosed with cancer while writing her final novel and wrote movingly about her illness earlier this year.
"The ground beneath my feet has never been more uncertain," she wrote in The Guardian. "But what is sure is... there is no vagueness about my mortality.
"I may be ill but I'm also warm and sheltered, surrounded by family and friends."
Dunmore also spoke about her illness on Radio 4's Open Book, saying she hoped her work would be read by her loved ones after her death.
"One of the things that does please me is that my grandchildren will be able to get to know me... through reading my books," she told Mariella Frostrup.
Penguin Random House, who announced Dunmore's death, said she was "an inspirational and generous author" known for "championing emerging voices and other established authors."
Her editor, Selina Walker, remembered her as "an exceptional person and an exceptional novelist [with] a legacy of exceptional novels".
Dunmore leaves behind her husband, Francis Charnley, three children/stepchildren and three grandchildren.

NVA has concluded missives with the Catholic Church for St Peter's Seminary in Cardross, Argyll and Bute.
The A-listed building was designed and built in the 1960s as a training college for priests but it has not been used since the 1980s and is now a ruin.
NVA aims to restore part of the seminary and use it as an art space.
Its plan would stabilise the structure and gradually restore some interior spaces for cultural and educational use.
The charity has already received £100,000 from Creative Scotland's National Lottery Fund towards the project.
It still needs to raise £2m by 2013 to take its proposals forward.
St Peter's Seminary was designed by Glasgow architects Gillespie, Kidd and Coia.
The Roman Catholic seminary, which belonged to the Archdiocese of Glasgow, was completed and consecrated in 1966.
The distinctive zig-zag design and concrete appearance soon brought architectural recognition to the site.
However, as numbers entering the religious life fell and with high maintenance costs, the decision was taken to close the college.
In 1980 the seminary was deconsecrated and fell into a state of disrepair.
The building was Category A listed by Historic Scotland in 1992.
The World Monuments Fund, which works to preserve endangered cultural landmarks, added St Peter's College to its register in June 2007.
The nuclear industry is looking at how it might use technologies being used in the decommissioning of North Sea oil and gas installations.
