Nuclear Energy
Gristol-Serkonos operates 50 nuclear reactors across the two constituent countries. The Kingdom of Gristol operates the 41 nuclear reactors while the League of Serkonos operates 9. All currently operating Gristo-Serkonan nuclear reactors either a domestic design, the Marklin-Ashton Energy G-series reactors, or foreign designs from Latium and Zacapican. The most common reactor type in the country are the pressurized heavy-water reactor while Zacapine-licensed reactors use a pressurized water reactor design. Several small modular reactors are currently under planning stage or under construction. The first nuclear reactor from Marklin-Ashton Energy was built in Ulstrand for GristolPower in 1966 and begun operation in 1971 with subsequent reactor units going online over the next two decades.
Several companies operate and maintain the reactors in the country. GristolPower initially operated all the reactors in the Kingdom of Gristol until 1998 when the heavily indebted company was reorganized into two entities, the Gristol Power Generation and the GristolHydro. Gristol Power Generation leased the operations of Aureille, Verwolde, Kristiansand, and Valberg Nuclear Generation Stations to GaxaEnergy. The collapse of GristolPower prompted Marklin-Ashton Energy to halt development of the fourth generation PHWR design, focusing on maintenance and upgrades on the current reactor fleet.
Majority of the Gristol-based reactors are either Marklin-Ashton PHWRs and Latium-licensed designs. SKF Energy operates the nuclear reactors in the League of Serkonos. All of the reactors in service are the Zacapine-licensed PWR designs.

Fuel reprocessing and safe storage
In order to comply with National Nuclear Safety Commission Report after a Level 3 Incident at the Atheclaghque Nuclear Generation Station, the nuclear energy suppliers jointly-operate the Hektoen National Nuclear Fuel Reprocessing Centre. Located in Hektoen in the northern Gristol region, the Hektoen NNFRC has been in operation since 1968 and has a capacity of about 1,700 tonnes per year. The Hektoen NNFRC utilizes an aqueous nuclear reprocessing method known as PUREX where 96% of the spent nuclear fuel are recovered. The site also operates a deep geological repository adjacent to the site where the non-recyclable fission products are vitrified along with compacted nuclear control rod hulls and endplates.
In compliance with federal regulations, vitrified fission products and compacted waste from spent nuclear fuel received from foreign countries are returned to the country of origin.
