RECOVERY ACTION: FOR INFORMATIONAL PURPOSES ONLY -- Nuclear Reaction Modeling for Actinides

RECOVERY ACTION: FOR INFORMATIONAL PURPOSES ONLY -- DUNS 785627931. The modification addresses the following work: Nuclear Reaction Modeling for Actinides (joint LLNL/LANL project). LLNL will develop a new technique to calculate the cross sections on actinides, in which the transition probability of fission is calculated based on a realistic multi-dimensional potential surface. The microscopic model will also be applied to dynamical fission processes to calculate fission-fragment properties and prompt fission neutron spectra Improved Prompt and Delayed Decay Spectra for Advanced Fuels. LLNL will provide the improved experimental nuclear data to the modeling of burning advanced fuels. In particular, LLNL will field the new measurement of the prompt gamma-ray radiation for neutron-induced fission on 241Pu in addition to the data analysis of existing data on other actinides. The contractor will be working at Lawrence Livermore.



The action is other than fixed price because it is in accordance with FAR 5.705(b), the rationale for pricing this action Other than Fixed Price is due to the fact that LLNS operates under a cost re-imbursement M&O contract and all costs are fully recovered. The other basis for Other than Fixed Price is because this is a Research and Development type work authorization and is therefore cost-reimbursable.



NOTE: This action is awarded under Modification no. M096 that recognizes Work Authorization no. KB/NS50/9/ARRA-2 issued under M&O Contract number DE-AC52-07NA27344. This action is funded by Recovery Act dollars.
