1. When does your organization issue the COLR to the Plant (e.g., as needed, before the start of the outage, 3 months prior to the outage) ? The COLR is normally accepted by our Safety Review team prior to the outage (2-3 weeks). The procedures that are updated are posted during the outage. Additionally, any changes during the cycle are processed as needed. 2. How long after issuance to the Plant is the COLR sent to the NRC? We generally send the COLR to licensing shortly after it is approved (within a week of approval). Licensing then has to write a cover letter and send the letter around for review and signature before it is sent to the NRC (this typically takes a week or two). Per RMD - We are supposed to send the COLR to licensing about 2 weeks after shutdown. We are supposed to verify that licensing has transmitted the approved COLR to the NRC 90 days after shutdown. 3. What organization prepares and issues the COLR (e.g. core design, safety analysis, licensing, etc.)? Our fuel projects group prepares and issues the COLR. Because it is a report and not as easily accessible at the site level, Reactor Engineering then updates a Design Reference Procedure that anyone at the site can access. We update the DRP during the outage (as noted above).

From: pwrrm@retaqs.com [mailto:pwrrm@retaqs.com] On Behalf Of Gore, Duane Sent: Tuesday, January 05, 2010 3:15 PM To: 'PWR Reactivity Management' Subject: [Pwrrm] Issuance of the COLR
We have been questioned by our Resident as to the timeliness of issuing the Core Operating Limits Report (COLR). We issue it after we approve our Reload Safety Evaluation report. Sometimes this is done before the refueling outage starts, other times it is just prior to core reload. Other than having it in place when the new core is loaded, we do not have any requirements on a lead-time. When we issue the COLR to the Plant we also issue it to Licensing and they do the formal transmittal to the NRC.
