Nuclear Security Exercises now available to all Nucleonica users

March 28th, 2019

In Nucleonica’s e-Learning center (e-Learn app), a series of nuclear security exercises has been released for all Nucleonica users.

These exercises have been developed jointly with Dr. Emily Alice Kröger from the Federal Office for Radiation Protection (Bundesamt für Strahlenschutz) and the Nucleonica Team. The exercises were developed for use in BfS training courses on Nucleonica held on a regular basis. Because of the general interest in these presentations, we have released them for general use by Nucleonica users.

webKORIGEN and DELNuS updates

March 26th, 2019

WebKORIGEN is a Nucleonica application for the simulation of the time evolution of a nuclide inventory in power reactors. A related application, DELNuS (Decay Engine for Large Nuclide Sets), allows the user to make decay calculations for a large number of nuclides (typically present in a reactor).
Following a new compilation (2019), a number of updates and improvements in the webKORIGEN and DELNuS applications have been made:
webKORIGEN:
– it is now possible to make Ra226 irradations in the flux mode.
– new tabs show the cross section data (also burnup dependent ) and decay data used in the calculations for the various reactor types.
– in the results grid, nuclide half-lives have been added

DELNuS
– a problem with using mixtures in DELNuS has been resolved.
– in the results grid, the nuclide half-lives have been added
– decay data used in the calculations are displayed

Ra-226 irradiations now possilbe with webKORIGEN

March 22nd, 2019

Qu. (from D. B. Garching, Germany):
Dear Nucleonica Team, if I let Ra-226 irradiate in a certain flux for a certain time, why I do not get nuclides with mass numbers higher than 226?

Ans. (Nucleonica Team)
This problem has now been resolved.

Results are shown below for an irradiation of Ra-226 (2g) in a dedicated facility with a thermal neutron flux of 2e14 neutrons per cm2 per s for a period of 100 days.
