I would like to evaluate more than 50 radionuclides.

[오신성]

Hello, everyone.

I am Shinsung Oh, majoring in nuclear engineering.
I am studying for the spent nuclear fuel nuclide release considering IRF and would like to evaluate the release rate through PFLOTRAN.
I'm currently using PFLOTRAN v4.0 in the Linux environment.

There are more than 50 radionuclides that I'm interested in.
For that reason, I got the following error message after running PFLOTRAN.
ERROR: More than 50 radionuclide species are provided in the WASTE_FORM_GENERAL,MECHANISM FMDM_SURROGATE, SPECIES block. Please email pflotr...@googlegroups.com and if reducing to less than 50 is not an option..

Is there any way I can increase these limits?

Thank you in advance.

Sincerely,

Shinsung Oh

Hi Shinsung,

 

It could be as simple as increasing the limit (k>50) to a different number and allocate more than 50 in the temp_species_array.

You can change the source code of pm_waste_form.F90 and try to see if it has any problem running more than 50 radionuclides.

If you could share what simulation you are trying to run, I can suggest whether PFLOTRAN is the right code to do it or not. Typically a field scale simulator do not handle more than 50 species.

 

          case('SPECIES')

            allocate(temp_species_array(50))

            do

              call InputReadPflotranString(input,option)

              if (InputCheckExit(input,option)) exit

              k = k + 1

              if (k > 50) then

                option%io_buffer = 'More than 50 radionuclide species are &

                  &provided in the ' // trim(error_string) // &

                  ', SPECIES block.'

                call PrintErrMsgToDev(option, &

                                       'if reducing to less than 50 is not &

                                       &an option.')

              endif

 

 

Best regards,
