can we calculate the effective delayed neutron precursor by OpenMC？

Hi all,
I read some papers about the calculation for effective Delayed Neutron Precursor (DNP) based on MCNP. The way of calculating the effective DNP is so called “prompt method”. This method in MCNP is described as:
Firstly, run K-eigenvalue calculation By turning off “beta term”, and then we can get the keff_prompt. Secondly, run K-eigenvalue calculation By turning on “beta term”, and then we can get the keff. At last, the effective DNP can be obtained by:

the effective DNP = keff - keff_prompt
I reviewed the user’s guide of OpenMC, and I didn’t find the specification about the calculation of effective DNP. So, can we calculate it by OpenMC ?

Best regards!

Hi yin,
Check this link where paul romano has given a solution of your question. You can do it but you have to change source code and install OpenMC in your machine.
