MARSSIM replacing NUREG/CR-5849

[Stephen McGuire <SAM2@nrc.gov>]

On March 14, Sue Dupre asked if the MARSSIM manual would replace
NUREG/CR-5849, Manual for Conducting Radiological Surveys in Support of
License Termination.

Yes, the NRC staff is considering replacing NUREG/CR-5849 with MARSSIM for
final site surveys performed by NRC licensees for license termination.  The final
decision on whether to endorse MARSSIM, in whole or in part, will depend to a
significant extent on the public comments received on MARSSIM.  (Comments are
due in July.)  

With that in mind, NRC licensees reviewing MARSSIM should review it as if it
were to be endorsed by the NRC as the acceptable method to conduct final site
surveys.
