LOSS OF TECHNICAL SUPPORT CENTER VENTILATION
"This telephone notification is provided in accordance with Exelon Reportability manual SAF 1.1 0, 'Major Loss of Emergency Preparedness Capabilities', and 10CFR50.72(b)(3)(xiii).
"On June 6th 2015 at 12:13 [CDT], it was determined that the onsite Technical Support Center (TSC) Ventilation System Supply Fan belts had failed, resulting in loss of ventilation for the facility. Repairs were not completed within the time required had the TSC needed to be staffed. There is currently no emergency event in progress requiring TSC staffing. If an emergency is declared and the TSC ERO activation is required, the TSC will be staffed and activated unless the TSC becomes uninhabitable due to ambient temperatures, radiological, or other conditions. If relocation of the TSC staff becomes necessary, the Station Emergency Director will relocate the staff to an alternate TSC location in accordance with
applicable site procedures.
"The licensee has notified the Senior Resident Inspector of the issue."
*** UPDATE PROVIDED BY TODD CASAGRANDE TO NESTOR MAKRIS AT 2305 EDT ON 06/06/2015 ***
"After repairs were completed, the TSC ventilation was restored to service at 2300 [EDT] on 06/06/2015.
"The licensee has notified the NRC Resident Inspector."

NOT MEETING TECHNICAL SPECIFICATIONS DUE TO INCORRECT LOADING OF CASKS
"On June 6, 2015, during a review of Independent Spent Fuel Storage (ISFSI) cask loading, plant personnel discovered that for two casks, preferential loading was not used during uniform loading as required by ISFSI Technical Specification 2.1.2, Uniform and Preferential Fuel Loading.
"ISFSI Technical Specification 2.1.2 requires that a preferential fuel loading configuration (i.e., that fuel assemblies with the longest cooling times shall be loaded into peripheral fuel storage locations) is used during uniform loading. Preferential loading was only partially met for two casks, designated MPC-253 and MPC-257. For these two casks, fuel assemblies with the longest cooling times were placed in the four center cask locations, which are only ones allowed for those assemblies containing control rods.
"Engineering has performed an evaluation and determined that the fuel casks remain in a safe and analyzed condition.'
"There is no adverse effect on the health and safety of the public.
"The NRC Resident Inspector has been informed."

"A full extent of condition review has determined that 17 of the 29 loaded casks in the Diablo Canyon ISFSI prior to the 2015 campaign were found to be out of compliance with ISFSI Technical Specification 2.1.2, Uniform and Preferential Fuel Loading. The casks were preferentially loaded based on heat load vs cooling time.
"Engineering has performed an evaluation and determined that the fuel and casks remains in a safe and analyzed condition.
"There is no adverse effect on the health and safety of the public.
"The NRC Senior Resident Inspector has been informed."
