Response below for Robinson From: [email protected] [mailto:[email protected]] On Behalf Of Ramirez, James Sent: Friday, November 11, 2011 12:10 PM To: [email protected] Subject: Powernet: RE: Powernet RCA Egress Benchmarking
DCPP is conducting benchmarking regarding RCA Egress processes: 1. Does your plant have any unmonitored (no RP presence) RCA egress points that are always opened? Yes. Based on our plant configuration and new rules we recently allowed Operations to have an RCA egress point - had to do with protecting the Inside AO (keeps him from having to turnover on station) Prior to implementing this we installed remote equipment such as a camera (we can use to record when/if we want) and an alarm module that gives us an alarm at our primary RCA boundary if an alarm occurs on a monitor at the Operations exit point. 2. Is your plant's normal RCA egress point staffed continuously by RP personnel 24/7? No we staff it continuously during day but we only have one shift tech so HP is not always present on backshift 3. What items, if any, does your Program allow a person to wear through the personnel contamination monitor and therefore be monitored for release, via the PCM? Examples include security key cards, TLDs, hard hat lights, items attached to lanyards (pens), items attached to belts (pagers, phones, knives). All of the above referenced items are typically allowed to be worn through the monitor with the exception of the knife. 4. What items, if any, does your Program allow a worker to self-survey from the RCA through a small article monitor (SAM) only (no frisk - no smear)? Examples include clip boards, pens, pocket contents. Paperwork (procedures, forms, books), Clip Boards, Pens and Pencils, PPE (other than fall protection), Personal Clothing, Hand Carried Radios, contents of pockets (we have empty pocket requirement) 5. Does your Program require personal items monitored with a SAM to be put back on and then worn through the PCM as well? No 6. If your Program allows workers to self-survey personal items, is the person permitted to repeat the survey on a single alarm or is there immediate RP intervention? RP must respond to any SAM alarm - first alarm. Radiation Workers are not allowed to remove any item that alarms SAM. 7. If an item alarms the SAM does your Program require multiple negative counts at a changed geometry before release? RP personnel must get involved and use SAM as a tool in determining if any licensed radioactive material is present in item prior to allowing its release 8. If several items alarm the SAM in the aggregate, how does your Program allow for the release the non-contaminated items once the contaminated item is determined? Must the items pass the SAM as an aggregate? What if no contaminated item can be determined? RP personnel must get involved and use SAM as a tool in determining if any licensed radioactive material is present in item prior to allowing its release. Items that are a unit are expected to clear SAM as a unit. For example, If gloves are released they are released as a pair, not individual gloves. 9. What management level of authorization, if any, is required to release an item from the RCA? Currently Sr. RP can release items without additional authorization, however we are in the process of reevaluating this as part of our goal of greatly reducing the number of items that require release.
