Need for Supplement to IL RT license amendment Ken, On October 27, 2016, NextEra provided responses to t he NRC staff's request for additional information (RAI) related to the license amendment request regarding extending containment leakage testing frequency. On November 28, we held a call with your staff to clarify the response to EMCB-RAI-2. As discussed during the call, the NRC staff would like you to clarify the fo llowing on the docket in a supplemental response. | |||
EMCB-RAI-2: | |||
The last sentence of the response to EMCB-RAI-2 states, "since the corrosion allowance for the base mat is less than the cylindrical liner plate, the corrosion analysis is bounded by the base mat analysis and further justified in the response to EMCB RAI-3." Earlier in the response the licensee states the corrosion allowance for the cylinder is 0.094" in general with a 0.1875" allowance for localized areas and the allowance for the base mat area is 0.125." | |||
It is not clear the quoted statement is accurate unless the licensee is referring to the localized corrosion allowance for the cylinder. The licensee should clarify the statement and if the localized allowance is being used a technical justification should be provided for use of the localized allowance instead of the general allowance. | |||

Need for Supplement to IL RT license amendment Ken, On October 27, 2016, NextEra provided responses to t he NRC staff's request for additional information (RAI) related to the license amendment request regarding extending containment leakage testing frequency. On November 28, we held a call with your staff to clarify the response to EMCB-RAI-2. As discussed during the call, the NRC staff would like you to clarify the fo llowing on the docket in a supplemental response.
EMCB-RAI-2:
The last sentence of the response to EMCB-RAI-2 states, "since the corrosion allowance for the base mat is less than the cylindrical liner plate, the corrosion analysis is bounded by the base mat analysis and further justified in the response to EMCB RAI-3." Earlier in the response the licensee states the corrosion allowance for the cylinder is 0.094" in general with a 0.1875" allowance for localized areas and the allowance for the base mat area is 0.125."
It is not clear the quoted statement is accurate unless the licensee is referring to the localized corrosion allowance for the cylinder. The licensee should clarify the statement and if the localized allowance is being used a technical justification should be provided for use of the localized allowance instead of the general allowance.
