What is a unit of time listed in MCNP6 PTRAC output file?

AI Thread Summary
The unit of time in the MCNP6 PTRAC output file is the shake, which equals 10 nanoseconds. This unit is commonly used in nuclear physics due to its relevance in the timescales of nuclear events and chain reactions. The discussion highlights the difficulty in finding this information in the MCNP manual. The user initially speculated that the time might be in milliseconds or microseconds, but the shake is the correct unit. Understanding this unit is essential for accurately analyzing PTRAC output data.

Time unit in MCNP6 PTRAC
Hi everyone,

I've been trying to analyze PTRAC output file from MCNP6

here we can see the location , cell, particle, time, and so on...

My question is, I have trouble finding the unit of time listed in PTRAC, (ex, 0.30113E-02), which is hard to find in MCNP manual

My intuition is that the time unit is in milisecond, or microsecond

Does anyone know the answer of this simple question?

The natural unit of time in MCNP is the shake. 1 shake is 10ns. It's a convenient scale for nuclear events and it's the right order for one generation in a chain reaction so there is a lot of history attached to it. Could that be the right for the parameter you are looking at?
 

Thread 'MCNP6 BURN Card Issue: Zero Burnup for Material in Fuel Assembly'

Hello everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information（power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.） for Material 2 is zero, while Material 1...

Thread 'Beginner Seeking Help: MCNP6 Burnup Example (OECD-NEA Benchmark)'

Hi everyone, I'm a complete beginner with MCNP and trying to learn how to perform burnup calculations. Right now, I'm feeling a bit lost and not sure where to start. I found the OECD-NEA Burnup Credit Calculational Criticality Benchmark (Phase I-B) and was wondering if anyone has worked through this specific benchmark using MCNP6? If so, would you be willing to share your MCNP input file for it? Seeing an actual working example would be incredibly helpful for my learning. I'd be really...
