Ginna has performed a neutron spectrum re-assessment since our up-rate. However, the reason for doing so was more due to changing dosimetry vendors at about the same time than specifically because of the up-rate. We felt we needed a better/more detailed understanding of the spectrum to ensure proper monitoring. Prior to the assessment, the neutron spectrum information we had was somewhat general/generic and several decades old.
