Columbia's response below.
1. Has anyone developed/implemented changes to their High Radiation Area Controls process that has resulted in appreciable efficiency gains for the Radiation Protection organization? Not within the last year. 2. What method do you use or what barriers do you put in place to ensure a RP technician returns a HRA/LHRA/VHRA key before leaving site at the end of his/her shift? All keys have an encumbering device attached to them when they are checked out, 4"X4" bright orange plastic. All keys are inventoried by the outgoing and incoming Lead HP Technician at the beginning of each twelve hour shift, the inventory form is completed and sent to Supervision for review. If so, how do you "guard" the LHRA whenever the shield door is required to be unlocked/open (tool head change, camera change, etc.)? Who performs this "guard" function (RP, platform worker)? Columbia (BWR) uses LHRA Guards whenever a locked high radiation area is accessed. LHRA door guards are briefed by HP Technicians and given a LHRA Door Guard Responsibilities form which they sign and keep in their possession until the LHRA door is locked. Anyone can be a LHRA door guard as long as they understand they have no other duties besides guarding access to the LHRA.

I would appreciate any and all responses. From: Helton, Mark Sent: Wednesday, November 16, 2016 10:54 AM To: [email protected]<mailto:[email protected]> Subject: Efficiency Gains in HRA Controls I am looking for any ideas/responses regarding the following questions/issues... 1. Has anyone developed/implemented changes to their High Radiation Area Controls process that has resulted in appreciable efficiency gains for the Radiation Protection organization? 2. What method do you use or what barriers do you put in place to ensure a RP technician returns a HRA/LHRA/VHRA key before leaving site at the end of his/her shift? 3. (For those using Sentinel) Does anyone use the "High Rad Keys" functionality in Sentinel to inventory, issue, and return HRA keys? 4. (For PWR only) Do you use lockable LHRA shield doors on your S/G manways during S/G maintenance activities in an outage? If so, how do you "guard" the LHRA whenever the shield door is required to be unlocked/open (tool head change, camera change, etc.)? Who performs this "guard" function (RP, platform worker)? Have you developed a method for sampling air or taking radiation readings inside the channel head without unlocking/opening the shield door? Thank you in advance for all responses.
