Composition of depleted materials

Jaakko, I run depletion calculation with set printm 1 option to get “<input>.bumat<n>” files. The fuel composition is as follows: mat ThPu 6.55665E-02 burn 1 90232.09c 2.0592E-02 94238.09c 2.2900E-05 94239.09c 7.4780E-04 94240.09c 2.9030E-04 94241.09c 1.5340E-04 94242.09c 5.0100E-05 8016.09c 4.3710E...

Re: Preserving the source distribution

It seems that MCNP stores x, y, and z-coordinates, u, v, and w-direction cosines, energy, weight, and time for each particle.

Preserving the source distribution

Jaakko,

As you definitely aware, source convergence in full core calculations takes a lot of time.

So it would be nice to have a possibility to save the source distribution and to use it in the following calculations (similar to MCNP SRCTP).

Iteration mode

Jaakko, I tried to run a PWR assembly model in the B1 iteration mode. I got the following: ==================================================================== Starting the transport calculation cycle... Sampling initial source... OK. Inactive cycle 1 / 25: k-eff = 1.11376 (DT thresh = 0.9000) Inact...

Generation of few-group XS in different group structures

Hi Jaakko,

I was wondering if it is possible to generate few-group cross sections in different group structures in the single run.
