<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">We use a high risk RWP for surveying under vessel area or keyway to down post from a VHRA to HRA and have RP supervisor on tag out of incore drive system to
prevent changes in dose rates. Then work in keyway is performed on a RWP that is not high rad risk. The same goes for our reactor cavity after shutdown VHRA posting removed and down posted to allow use of non-high risk RWPs.

should use during the course of work involving radiological controls. Criteria RP.2-4 discusses high-risk work activities. In one section of RP.2-4, 05-008 mentions reclassification of high-risk work as medium or low radiological risk once, “…initial surveys
are complete and protective controls are established and validated…”. <o:p></o:p></span></p>
