How Far Is it from Chicago to Boston? 

Well... That Depends How You Measure It

“What on earth is a Smoot?” was the question John and I found ourselves pondering in Boston, standing on Harvard bridge on our way to MIT.

This unit of measure became the perfect metaphor for the distance travelled on our epic journey across America promoting Cyclone Sage - our new AI assistant integrated into Cyclone (Orthrus Software) designed to support nuclear engineering and fusion workflows. It was a trip full of amazing experiences, with some serious science folded in too. 

One Smoot, as it turns out, is precisely the length of MIT student Oliver Smoot (5 ft 7 inches), who repeatedly lay down end-to-end across the Harvard Bridge in 1958, creating one of academia’s most eccentric units. The bridge is exactly 364.4 Smoots long, plus or minus one ear. 

ANS Conference – Cyclone Sage and Deep-Dish Pizza 

Distance Travelled: 17.5 miles / 18,480 Smoots (O’Hare Airport to downtown Chicago) 

We began our journey in Chicago at the American Nuclear Society (ANS) conference where we caught up with lots of familiar faces. Here, we introduced our AI assistant, Cyclone Sage, designed to streamline the creation of input decks for MCNP. Sage garnered significant interest and thoughtful discussion, and it was great to see enthusiasm for an AI solution carefully tailored to meet the needs of the nuclear sector. 

Aside from the conference, Chicago itself was a brilliant city. We marvelled at the city’s skyline, took in views along the iconic Chicago River, and tackled the legendary deep-dish pizza. Let’s just say we hit a delicious but formidable “cheese wall” at Labriola restaurant, a battle both John and I lost. 

Argonne National Lab – High Energy Research and Reactor History 

Distance Travelled: 24.5 miles / 25,872 Smoots (Chicago to Argonne) 

Upon leaving Chicago, we toured Argonne National Laboratory, an epicentre of nuclear history and cutting-edge research. Here, we glimpsed the remarkable Advanced Photon Source - an immense high-energy X-ray facility where researchers worldwide collaborate on groundbreaking science.  

A highlight of the tour was the chance to touch a graphite block from the historic Chicago Pile 1 - the world’s first nuclear reactor. Additionally, we learned a great deal about Argonne’s pioneering work in science, including sodium-cooled reactor technology and exascale computing. 

Road Trip Begins – The Open Road 

Distance Travelled: 210 miles / 221,760 Smoots (Argonne to Holiday City) 

Check out the decals...and always get the damage waiver!

For the next stage of our journey, our trusty GMC Sierra V8 pickup truck carried us eastward on the I90. Despite being absolutely massive, it was surprising easy to drive and powered us comfortably along, towering above almost everything in sight. Arriving late at a rather quirky hotel, we had a brief but memorable pitstop, with our sights set firmly on reaching the stunning spectacle of Niagara Falls the next day.

Cleveland to Niagara – Rock & Roll, Harleys, and brief trip to Canada 

Distance Travelled: 359 miles / 379,104 Smoots (Holiday City to Buffalo via Cleveland & Niagara) 

Our next stop brought us to Cleveland’s Rock & Roll Hall of Fame, which pays tribute to iconic bands like The Beatles, The Rolling Stones, and even… Def Leppard. With eardrums still intact, we found a playlist with 100s of hall of fame hits which got us through the many miles of driving. As we continued our journey, we visited a very cool Harley-Davidson dealership, where we had to resist swapping the trusty pickup for two hogs.

Arriving at Niagara Falls was amazing, especially after hearing enthusiastic reviews from people we’d chatted with at ANS. They suggested we cross the Rainbow Bridge into Canada for the best views, and they weren’t wrong. Fortunately, the border officials let us back into the States after buying quite a lot of maple syrup. 

A bit too much moderator in this CARTA simulation

Finger Lakes to Springfield – Nature, Baseball and Some American Culture 

Distance Travelled: 240 miles / 253,440 Smoots (Buffalo, NY to Springfield, NY, via Montezuma, Skaneateles, and Cooperstown) 

Leaving the interstate we drove through the tranquil Finger Lakes region, stopping at Montezuma Wildlife Refuge where a huge eagle statue stands on the roadside. Birdwatching with binoculars from Nuclear Talent Scout exhibiting at ANS was great - thanks for freebie, they were put to good use!

Continuing our drive, we made a memorable stop in the lakeside town of Skaneateles, enjoying much needed coffee and pastries. The locals found it quite amusing when we said “cheers” after receiving our coffees as apparently this doesn’t quite translate in the USA (along with other phrases like: “we need to get a wriggle on” and: “that’ll take donkeys years”). The town was distinctly upmarket with lots of American flags, the same with all the towns we drove through. It was quite a sight.

Cooperstown guided us through the history of baseball, revealing how it united communities across the states. We unfortunately missed attending a ball game in Chicago due to heavy rain, but there’s always next time! Springfield offered us some excellent German cuisine from a local recommendation, reminding us how cultural influences are very broad across America.

The Last Leg – Battleship Cove and on to Boston  

Distance Travelled: 154 miles / 162,624 Smoots (Springfield, MA, to Boston via Battleship Cove in Fall River) 

Battleship Cove near Boston gave us a look into maritime history, exploring the USS Massachusetts and USS Swordfish, a humbling reminder of the bravery of people during WW2. Experiencing the confined spaces and harsh conditions onboard made us appreciate just how tough life must have been for the people who spent months at sea. We then departed to Boston. After 4 days of travelling, we were both tired but there was no time to waste! We were straight into the SOFE conference the very next day.

Symposium on Fusion Engineering (SOFE) 2025

In Boston, our focus turned to fusion energy at the Symposium on Fusion Engineering (SOFE), where we were warmly welcomed by familiar faces. All of the fusion industry leaders were present, UK Industrial Fusion Solutions (UKIFS), Commonwealth Fusion Systems, Tokamak Energy, and Proxima Fusion, just to name a few. A highlight was a bespoke tour given by Rémi Delaporte-Mathurin (MIT) who showed us around the cutting-edge LIBRA tritium breeding experiment. We expressed our thanks with a limited-edition Cerberus Nuclear mug and Yorkshire Tea, essential provisions for any fusion scientist.

Our poster session promoting Cyclone and Cyclone Sage for fusion neutronics analysis was very well attended. The level of engagement was fantastic; both John and I nearly lost our voices from the sheer number of people we spoke to.  

Visiting Commonwealth Fusion Systems’s SPARC was genuinely impressive. The rapid progress made has only heightened our excitement for fusion energy’s potential. Lookout from them in 2027 when its due to be turned on. 

Thank you CFS

It's a long way from Chicago to Boston 

Of course, we couldn’t leave Boston without visiting where Smoot’s story began, it turns out I’m slightly taller than one Smoot! Most visitors who walk across the Harvard bridge rarely notice the marks that are repainted every year, making it a fascinating hidden piece of MIT knowledge.

If you would like to learn more check out Matt Parker’s brilliant Stand-up Maths video, "The bridge which is measured in smoots”.

So how far is it from Chicago to Boston? Well, it's about 1005 miles, or 1,061,280 smoots +- 1 ear, and probably quite a bit more if you include how many steps we did! With that, our journey across the USA came to a close.

After all this it’s easy to forget that this whole adventure was about Cyclone and Cyclone Sage. So if you’re curious what Orthrus Software are up to, drop them an email (support@orthrussoftware.com) or check out orthrussoftware.com.  

OpenMC Internal Training

Last week, John Billingsley from our Radiation Shielding team ran a full-day internal training session on OpenMC - a Monte Carlo particle transport code used for simulating neutron and photon transport. 

OpenMC is a community-developed, open-source code that has gained popularity for its flexibility, active development, and integration with Python. It is widely adopted in the fusion energy sector, where its ability to perform high-fidelity simulations makes it a valuable tool for design and analysis. Increasingly, OpenMC is also being adopted in other areas of the nuclear industry as interest in modern, open-source tools continues to grow. 

The training was well attended by members of both the shielding and criticality teams and was structured as a mix of short lectures and hands-on exercises. John introduced the main concepts of building models with OpenMC, including using its Python API to define geometries and materials, set up source terms, and run transport simulations. Attendees had the chance to follow along with practical examples and try building their own models themselves throughout the day. 

The informal workshop format encouraged plenty of discussion, and it was a great opportunity for colleagues to explore how OpenMC might be applied in future projects. It was also a valuable chance for Cerberus to build upon our existing experience and expand our capabilities in the use of modern Monte Carlo transport codes. 

Thanks to John for putting together such an informative and engaging session and for helping more of the team get familiar with OpenMC. 

OSSFE Conference 2025

Last week, our shielding consultant, John Billingsley, had the opportunity to attend the Open Source Software for Fusion Energy (OSSFE) Conference – a first-of-its-kind event dedicated to advancing the development of open-source tools within the fusion energy community. The conference brought together researchers, developers, and enthusiasts from around the world to share exciting open source developments designed to accelerate progress in one of the most complex scientific challenges of all time.

Throughout the day, there was a wide range of engaging sessions and discussions, including technical talks, poster presentations, software demos, Q&A panel sessions, and informal meetups. Researchers presented on a broad range of topics including plasma physics, neutronics, tritium transport, and materials science, and showcased new tools in practical software tutorials.

The event was hosted through Gather in fully customized virtual platform which had been designed to replicate a real-world conference space. This wasn’t something we’d used before and was an interesting new environment to explore. You could navigate the space just like a real conference – dropping into rooms where presentations where happening or using proximity chat to strike up conversations with other attendees as you “walked” past. It brought a surprisingly authentic feel to an online event.

A huge thank you to the organising committee - Rémi Delaporte-Mathurin, James Dark, Jonathan Shimwell, Nick Murphy, Patrick Shriwise, Samuele Meschini, Ethan Peterson, and Julien Hillairet – for putting together such a well-organised and engaging event.

Cerberus Present at the American Nuclear Society Annual Meeting

We recently presented two papers at the American Nuclear Society Annual Meeting in Anaheim, California. The papers were presented within the Nuclear Criticality Safety Division (NCSD) Topical Meeting and were titled:

  • CARTA – Criticality Safety Virtual Reality Training Aid, Recent Developments.
  • Cyclone – Monte Carlo Data Processing and Visualization.

Katrina presented the CARTA paper and won the best paper award within the ‘Knowledge Transfer – Education, Professional Development, and Training’ track. The trophy (a prestigious NCSD thermos mug!) was presented at the NCSD awards dinner. The UK was well represented at the conference, with Katrina picking up her award alongside Amy van der Vyver from Sellafield Limited who presented a paper on the ‘UK Working Party on Criticality Webinar Series to Support Continuing Professional Development’. Liam Payne of Nuclear Waste Services (NWS) presented a UK perspective on Post-Closure Criticality Safety, and Alfie O’Neil from NNL presented a paper on Benchmark Experiments.

Cyclone and CARTA were really well received. Cyclone visualisation of MCNP models featured in a presentation by colleagues at the University of New Mexico. Stewart and Katrina were on hand with VR headsets to demonstrate CARTA, giving attendees the chance to (safely) cause a criticality in a glovebox.

Thanks to the ANS and, in particular, our colleagues within the NCSD who made us feel very welcome at the conference.
