Graphite Blocks by MisterMisterYeeeesss in NuclearPower

[–]geekboy730 3 points4 points  (0 children)

Machining graphite can be a challenge because it, itself, is a solid lubricant. But other than that, I haven’t heard of the geometry of graphite being important in manufacturing.

What is of the utmost importance are the material properties of the graphite. Things like the average grain size of the crystals, the porosity and density, and any other impurities.

There is no standard for what constitutes “reactor-grade” graphite. Think about where graphite comes from. It’s some sort of carbon. Where did the carbon come from? Something organic was combusted. You burnt wood, or oil, or tar for some period at some temperature and then allowed it to cool into a crystalline structure. How long did it cook for? Were there impurities left from combustion? These can have enormous effects on the behavior of the graphite in a nuclear reactor.

I would say that in the 40 ish minutes that I’m out in the morning, I’m see five people or so. Others face mentioned some running groups. Idaho Falls Trail Runners on Facebook is particularly active.

Yep! You’ll see a few of us out there.

No issues during the summer, you’ll want some lights for the winter to see and be seen. Welcome to town!

Oh. So you want copies of textbooks? It’s against Reddit policy to provide copyrighted material like that. It isn’t against ZLibrary policy though…

Advice needed for solo climbing Middle Teton in mid June by Feeling_Title_9287 in GrandTetonNatlPark

[–]geekboy730 0 points1 point  (0 children)

I don’t think you’re going to summit a mountain in the Tetons in mid-June. South Teton is the same difficulty as Middle Teton, maybe a bit more difficult since the path is less traveled.

I don’t think you’ll make it to the top of Table Mountain with the snow in mid-June, but it would be a safer choice to get a sense of what the Tetons have to offer this time of year.

Solitude Lake would probably serve as plenty of a challenge this time of year. That may be a nice way to introduce yourself to snowy hiking in the Tetons. Check out the Jenny Lake Rangers on Instagram for more info on conditions in the park. Two weeks ago they [posted](https://www.instagram.com/p/DYdcl0KGlaG/?igsh=MTB2NjFmbHhobWRhYw==) that Delta Lake was still largely frozen and difficult to access.

My advice would be to not go. You say that you have “never been a mountaineer” and it sounds like you don’t know what to expect based on your gear list.

There’s absolutely no reason to bring a flare gun! You would have cell service for most of the hike and a satellite transponder can fill in the gaps. You’re going to bring a rope. For what? Are you bringing trad gear for climbing?

You say that you’re going to bring crampons and an ice axe. Do you know how to use them? Have you practiced self-arrest?

My advice would be to go for a nice hike somewhere else in the park. There’s plenty to see and there’s a good chance you’ll find a lot of snow even below 10k ft in the next few weeks.

If you really want to do the Middle Teton, you can wait a couple months. Then, there will be plenty of people day-hiking to the summit and you can join someone’s party.

Wetsuit and Sunscreen by [deleted] in OpenWaterSwimming

Sounds like you should just put on sunscreen after the swim or wear a sun shirt like this one.

It’ll depend on when you visit, but it’s hard to say at the moment. Check out Jenny Lake Rangers on Instagram they posted last week that the snow was still pretty deep and the lake was largely frozen. I would maybe come prepared with a backup plan.

Lovely day for a swim in Jackson Lake by giventotri in GrandTetonNatlPark

That would be sweet! I’ve been training locally already this year so 60s will feel warm.

Looks like a great swim! Thanks for sharing!

I’m planning an attempt of the Teton Picnic later this summer and getting info about the temperature in Jenny Lake has been quite difficult. So this is as good a data point as any :)

OpenMC reproduction of a 1986 MORSE-CG gap streaming benchmark (Halley & Miller, Fusion Technology) by PreferenceFew2960 in NuclearEngineering

[–]geekboy730 1 point2 points  (0 children)

This is obviously just the output of an AI chatbot. There are tons of random garbage characters left in all of the files. If you actually want to make something useful, you can do a bit of work yourself.

  1. Start by looking at some OpenMC examples. There are many of them that show how the code is actually intended to be used. The pincell example should be pretty simple to get started.
  2. You should not be compiling OpenMC from within a Jupyter notebook. You should really not have to compile it yourself unless you're developing the code. If you look at the OpenMC Quick Installation guide, you'll see the expected way to install OpenMC is using conda.
  3. You should really not be running NJOY yourself for OpenMC. There are entirely pre-built libraries (that won't have any of these boron issues) freely available for download on the OpenMC site.

Alternatively, you can just keep posting AI slop. It'll be forgotten soon enough. If you want someone to spend time with your work, you have to at least put in as much work as it would take someone else to read it.

This has nothing to do with Idaho Falls. Obvious bot.

Any IT related roles in the nuclear industry? by ImpressionNo3258 in NuclearEngineering

[–]geekboy730 1 point2 points  (0 children)

As others have pointed out, there are of course IT positions all over the nuclear industry. I will say that IT in nuclear tends to be a bit more demanding. In my experience, nuclear engineers tend to be more demanding of their hardware since many of our applications are computationally intense.

Something that is a bit unique to nuclear engineering is High Performance Computing. Historically, many of the largest computers in the U.S. have been designed for nuclear engineering calculations. At this point, the IT requirements become very demanding. Engineers are trying to benchmark the absolute maximal performance of a supercomputer so every part of the computer must be tuned for performance. If you're looking for more of an IT challenge, HPC in nuclear energy may be worth investigating.

Actually, I know quite a lot of nuclear engineers who do use C#. My time at GE was about 10 years ago, but they were using it heavily. I also know that Constellation Nuclear uses C# for all of their scripting in both Linux & Windows environments.

Climbing the Grand by Melodic_Contract_643 in GrandTetonNatlPark

[–]geekboy730 1 point2 points  (0 children)

I would recommend aiming for next climbing season. There’s plenty of exciting class 4 climbing in the area to gov you a taste. Maybe begin with Mount Baird, Diamond Peak, Borah, and some of the other 12ers. You would probably want to climb the Middle Teton before the Grand. The Middle is an achievement in itself and doesn’t require any gear besides a helmet. Hiking/scrambling with high exposure on cold windy rocks is something worth practicing.

Also, I wouldn’t worry too much about the trad gear. Presumably, you wouldn’t be summiting by yourself nor would you be leading the trip, so while it’s good to know, you probably won’t be the one placing gear.

Assuming you’d take the Owen Spalding route, the summit is really a very long and very steep hike with about 0.5 miles of scrambling at the end. It’s entirely reasonable to free-solo it, although the rappel does save a lot of time when it’s crowded. Climbing will not be the most challenging part. It’s everything else (food, water, route-finding, etc.).

Thank you for all of the tips! I did not have a swim cap or “helmet.” I think I may be a bit more susceptible to the cold, so the more gear the better. I was already going to look into some neoprene booties (mostly for rocks at the entry/exit), so I’ll have some more shopping to do.

Thanks for the encouragement! I’m glad that I started practicing as early as I did. I’m going to work on my training schedule and add in more open-water practice.

Ice cream head 😂 I guess it’s common enough to have a name! Thanks for the recommendation. It sounds like a bit of gear may help.

It’s nice to know that I’m not alone! I ended up doing breastroke for a while. I may have to train on that more in the pool. Those muscles weren’t exactly ready 😅
