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.
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) ? Prior to startup and during the cycle for emergent issues. 2. How long after issuance to the Plant is the COLR sent to the NRC? Typically two weeks after issuance 3. What organization prepares and issues the COLR (e.g. core design, safety analysis, licensing, etc.)? Fuels prepares, Reactor Engineering processes and site Regulatory Assurance issues to the NRC.
Thank you in advance for your responses.
