Have you tried activating it with a Kerbal Engeneer on EVA? When a EVA Kerbal is Close to the engine, it should have the ability to active the reactor.

I hadn't, it was on a station core I was shipping interplanetary and then constructing in-situ. I use life support mods so shipping it over unmanned was my preference.

It's a nice challenge to need to have a crew rendezvous with the nuclear rocket prior to shipping OR come up with a design where the core can be activated on the launch pad without shredding the extendable radiators. Tempers the upgraded Timberwind a bit. Thanks for the info.

Do you take contributions to the wiki pretty freely? It seems like a lot of digging is necessary to get "good" at KSPIE and there's a lot of helpful but unfortunately outdated or incomplete information in random corners of the internet. If I could find all of the info on the wiki I would happily have read it cover to cover (I have read it cover to cover, it's just incomplete and outdated). I bet some community contributions in a central spot could spark a real makeover of the documentation.

Any help including help in improving docmentation would be welcome

I'm not sure but I believe everybody can can the wiki, if not I can add you as a collaborator.

Can someone explain the physics behind the nuclear LIGHTBULB?

If you increase thrust (increase the propellant mass flow) with the thrust the ISP and thrust increase.

However when increasing the mass flow with the slider, thrust increases and ISP decreases.

The Nuclear Lightbulb, takes a bit of time to get to full temperature and it performance better when approaching maximum power output where maximizes Isp but performance will be reduced at lower throttle where the reactor core operates at a lower core temperature. By default the Closed Cycle Gas Core tries to maximize isp, but when you need more thrust, like durring assend from a gravity well, you have the option to increase the mass flow, effectivly lowing the temperature the propellant is heated to , which will effectivly increase thrust at the expense of isp. THe ability to operate anywhere and able to increase gears makes it one of the most versitale engines available.

There's a build of KJR that will show the added autostruts, that's what those lines are. I thought it had a ui to enable and disable but my memory is a little foggy and every currently available fork of KJR krakens my craft to pieces eventually. I don't find it all that useful in modern KSP, anyway. The occasional autostrut or quantum strut always fixes even the wonkiest designs for me. 

Yep :) TY this was it.  I had simply missed the ui menu.  I knew it would be something simple that I was missing lol.  TY very much :)

Hi, I made a ship with Nuclear Lightbulb engine using liquid fuel, but the Isp in vacuum is only 700s. For this combination of engine and fuel Isp shoud be 1400s (0,8*22,136*Sqrt(6250)) as the formula in the part description says. But for some unknown reason, Propellant Isp modifier is only 0,400 and not 0,800. See the photo for details: https://imgur.com/a/PtPO4Qt

Am I doing something wrong or is it a bug?

I'm running KSP-IE 1.21.7.4 on 1.7.0.2483 KSP base game

No, but the information in the Part info screen is incorrect, the Isp ration of Liquid Fuel for Gas Cores is not 0.8 but 0.4, so your Isp will only be 700 instead of 1400.

@Vanamonde All good, it was acting inconsistently on my end so I wasn't sure if anything was happening! 

@FreeThinker Any idea about this engine animation glitch?

I don't know, I don't think KSPIE has anything to do with it, I need to look at the logs  to give any judgement on what might be the problem

I'm running the latest version of the mod and game with other mods, so I'm fairly sure this isn't a problem with KSPIE. Consider disabling a few mods at a time to see which one is causing this?

@FreeThinker Here is my log.

@wkwied I was looking in to this issue last night, and I saw a few other instances of it occurring for others. Speculation was generally KSPIE, and the only other mods I updated were Filter Extensions and Toolbar Control, which I wouldn't imagine would affect this, but then again you never know... 

However, given the fact that I have seen this occur for others who were using this mod, I would be eternally grateful if FreeThinker would have a look at my log and offer whatever perspective (s)he might have. 

Thank you!

I too also have this engine animation glitch as well for the same engine, for the NERVA.

@lobf We share the following mods:

Interstellar suite

KAS/KIS

So it could possibly be an animation misfire for the engine.

Well at least for NERVA I found a small mistake which cause KSPIE not to be present on the NERV , but  fixed it, but  the  observed effect is realy weird

Looking through the log I notice the following:

@lobf, I can now confirm the observed behavious. the fix is simple

open WarpPlugin\Parts\Engines\NERVA\NERVA.cfg

find and replace

 

	running_open
	{
//		AUDIO
//		{
//			channel = Ship
//			clip = sound_jet_deep
//			volume = 0.0 0.0
//			volume = 0.1 0.5
//			volume = 1 1
//			pitch = 0 1
//			pitch = 1 1.25
//			loop = true
		}
	}

by

	running_open
	{
//		AUDIO
//		{
//			channel = Ship
//			clip = sound_jet_deep
//			volume = 0.0 0.0
//			volume = 0.1 0.5
//			volume = 1 1
//			pitch = 0 1
//			pitch = 1 1.25
//			loop = true
//		}
	}

notice where "//" is added in front of "}"

Alternatively delete NERVA.cfg from WarpPlugin\Parts\Engines\NERVA

Where to get megajoules ???

 

1,000 EC, electrical charge, is 1 MJ. It can be freely converted between the two.

There is electricity on the ship but no megajoules

If MJ is not in the resource window, then nothing on the ship requires MJ

There are engines that run on xenon and megajoules
