Our criticality safety assessor Sarah recently went on a trip to Los Alamos, New Mexico. This was not inspired by the latest Oppenheimer film but rather to attend the MCNP Intermediate Training course run by Los Alamos National Laboratory (LANL).
During the training, Sarah got to grips with using the MCNP 6 code, building advanced geometries and sources, understanding advanced outputs and was introduced to a selection of variance reduction techniques. She also came back with a few insights to the updates in the latest MCNP 6.3 release. The course was a mixture of lecture and practical content, taught by a variety of MCNP developers from LANL whose expertise and patient instruction was greatly appreciated.
There was also opportunity to discover more about the history of Los Alamos itself, from the Ancestral Pueblo peoples, through Spanish occupation (the name “Los Alamos” means “The Cottonwoods” in Spanish) and homesteaders leading to the eventual requisition of the land in support of the Manhattan Project and the later impact of the Cold War.
Now she’s back, Sarah is looking forward to implementing her learning in support of client projects.
International Conference on Nuclear Criticality Safety
Cerberus Nuclear recently attended the International Conference on Nuclear Criticality Safety (ICNC) in Sendai, Japan. Held every four years, ICNC is an opportunity to learn about new and novel things happening around the world in criticality safety and well as giving those in attendance an opportunity to discuss criticality concepts with their international colleagues. It was also a great opportunity to see some sights in Japan and spend time with our UK colleagues!
Cerberus nuclear were proud to participate in the conference presenting the following papers:
‘Strategic Characterisation to Support the Development of Criticality Safety Assessments for Decommissioning’ by Tom Page and Barrie Greenhalgh.
‘Implementation of CARTA into Criticality Training Programmes’ by Katrina Christaki, Toby Tyas and Stewart Hay.
‘Cyclone – New Features for Criticality Safety Analyses’ by Stewart Hay, Carl Hughes and Peter Taylor.
As the conference was located in Japan, a number of papers were presented detailing the unique criticality challenges of decommissioning the Fukushima Daiichi nuclear power plant. Cerberus Nuclear joined a technical tour to the former power plant, where decommissioning activities were taking place. We visited the Interim storage Facility for Removed Soil and Waste and the tour ended at the site of the accident with each reactor in a different state of decommissioning.
As well as arranging a variety of interesting paper tracks in the conference itself, the organisers arranged a banquet with authentic Japanese food and entertainment which was very well received!
Cerberus would like to thank the conference organisers on a very successful conference and look forward to the next ICNC that will be held a bit closer to home in Manchester, UK.
While in Japan, Stewart and Tom also attended the British embassy in Tokyo to meet the fantastic nuclear trade team there and discuss potential opportunities with a Japanese company. Subsequently, Cerberus Nuclear have been included in the Buyer's Guide to the UK Nuclear Industry, which has been developed for the Japanese Market by the UK Department for Business and Trade.
NTEC N13 Criticality Safety Management
Cerberus Nuclear recently supported the NTEC N13 Criticality Safety Management module, delivered by Stuart Christie at the University of Manchester. Stewart Hay provided a talk on criticality safety assessment with a focus on real-world experience of delivering criticality safety assessments across the UK.
For Stewart, it was a pleasure to be back involved with a module he undertook as a student back in 2005/6, and one that sparked his interest in criticality safety.
The Nuclear Technology Education Consortium (NTEC) was established in 2005 following extensive consultations with the UK nuclear sector, including industry, regulators, the Ministry of Defence, the Nuclear Decommissioning Authority, government departments and the Cogent Sector Skills Council. The seven UK universities and higher education institutions in the Consortium provide flexible postgraduate training for the nuclear sector with the breadth and format of the training designed to meet the UK’s projected nuclear skills requirements in decommissioning and clean-up, reactor technology and fusion.

Cerberus Nuclear at SOFE 2023
Cerberus Nuclear recently attended the IEEE Symposium on Fusion Engineering (SOFE) in Oxford. The biennial conference with a focus on fusion excellence brings together scientists, engineers, researchers and industry professionals working in the field of nuclear fusion, providing a platform to exchange knowledge, collaborate on research, and discuss the latest developments in the field of nuclear fusion. The conference also provides opportunities for large fusion projects from both the public and private sector to showcase the progress of their powerplant initiatives.
Cerberus Nuclear were proud to participate in the conference programme, with John Billingsley presenting a poster to showcase the work of his recent development project. The project focussed on the development of optimisation techniques to inform the design of layered neutron shields using material cross-section data. The work generated a lot of interest, with optimisation techniques like this likely to play a key role in the design and delivery of commercial fusion reactors.
The week-long conference concluded with a tour of UKAEA’s Culham campus which is home to several major fusion research facilities and projects including the Joint European Torus (JET), which has been one of the world’s most significant experiments for achieving controlled fusion. The world-recognised campus is at the heart of fusion research in the UK, and is undergoing rapid development to be able to further innovate and solve challenges across the fusion sector and beyond. The tour also saw private fusion companies First Light Fusion and Tokamak Energy showcasing their latest technologies for achieving fusion.
Thank you to UKAEA for hosting a fantastic conference, and Cerberus Nuclear look forward to collaborating across the fusion industry to contribute to the realisation of clean, limitless energy.
Katrina Elected as WPC Secretary
Cerberus Nuclear is an active member of the Working Party on Criticality (WPC). The WPC is a formal sub-group of the Safety Directors Forum. The WPC’s focus is criticality safety issues up to, but not including, experimental and in-core power reactor operations. The issues considered are relevant to fabrication, transportation, storage and other operations relating to nuclear materials (e.g. new build, enrichment, reprocessing, decommissioning and long-term waste management).
Katrina Christaki, one of our criticality safety assessors, has recently been elected as secretary for the WPC. This role involves preparing the agenda and minutes for the meetings as well as management of the WPC papers. Katrina is excited to take on this key role supporting the activities of the WPC.
Cerberus Nuclear Offsets Carbon Emissions with Ecologi
Cerberus Nuclear is committed to reducing its carbon footprint. Our Environmental Policy states that we accept responsibility for the harmful effects our operations have on both the local and global environment, and that we are committed to reducing them. We are proud of the steps we are taking to reduce our environmental impact.
Some of our company benefits that help reduce our company emissions are:
Electric Car Lease Scheme - a salary sacrifice scheme available to the whole company. Employees can use the cars for both business and home, reducing their emissions.
CycleScheme - a salary sacrifice cycle to work scheme with a budget of £10,000. Employees can also purchase electric bikes through this scheme.
