INFORMATION REQUEST TO SUPPORT UPCOMING TEMPORARY INSTRUCTION 2515/193 INSPECTION AT DRESDEN NUCLEAR POWER STATION, UNITS 2 AND 3

Dear Mr. Hanson:

This letter is to request information to support our inspection of the Implementation of EA-13-109: Order Modifying Licenses with Regard to Reliable Hardened Containment Vents Capable of Operation under Severe Accident Conditions beginning July 23, 2018, at your Dresden Nuclear Power Station, Units 2 and 3. This inspection will be performed in accordance with the U.S. Nuclear Regulatory Commission (NRC) Temporary Instruction 2515/193.

In order to minimize the impact that the inspection has on the site and to ensure a productive inspection, we have enclosed a list of documents requested for the inspection. Please provide this information prior to July 6, 2018. It is important that all of these documents are up to date and complete in order to minimize the number of additional documents requested during the preparation and/or the on-site portions of the inspection.

Existing information collection requirements were approved by the Office of Management and Budget, Control Number 3150 0011. The NRC may not conduct or sponsor, and a person is not required to respond to, a request for information or an information collection requirement unless the requesting document displays a currently valid Office of Management and Budget control number.
