Hi,
Diablo Canyon did the following in our response to ANI Bulletin 11-02:
Formal Process to assess future neutron personnel dosimetry
New neutron dosimetry are tested per the NVLAP accredited dosimetry vendors
procedures. Diablo Canyon ensures that the provided neutron dosimetry is
accredited in the appropriate ANSI/HPS N13.11 performance categories for the
types of radiation at DCPP.
Formal process to evaluate design changes affecting neutron exposure.
We put a step in our plant administrative procedure governing design changes.
It requires that RP be involved in the process if a design change could affect
the neutron spectrum.
If you have any questions, please let me know.
Thanks,
Linda
