Mechanical – F3 Manhole- Sump Replacement, parts received, to be scheduled during Shutdown – PV07- MI60 Pump Vault 7, 150 Hp. Pond Pump Suction Valve won’t close, requires shutdown of both Pumps to repair Pump, replace valve, (need schedule for repair).

Mechanical (Cont.) – Site Wide Valve Exercising, V.I.P.E.R. Roll-out Annual Valve Exercising required by NFPA 25 Valve Intuitive Powered Equipped Rover (V.I.P.E.R.) Purchased, Software, Exercising Procedure and Commissioning Completed Domestic Water Valve Exercising in Village has been completed, Main Site WIP

Mechanical, (Cont.) Site-Wide ICW Flush Completed, Live Zebra Mussels Found at following locations: – IHFP-612Across from IARC/OTE – IHFP-107AP10 – IHFP-109AP30 – IHFP-110AP50 – IHFP-111AP0 – IHFP-185KRS – IHFP-203F0 – IHFP-041B0 – IHFP-113NE Wilson Hall – IHFP-106S Corner XG and TRG – IHFP-216D0 Outback

Tritium In Sewers (cont.) Tritium in the Sewers Source Identified as CUB Softener Sampling Discharges, (further testing required to verify as sole source).

Mechanical (Cont.) RHC5 XG Operators Room (Light Side) Reheat Coil #5 supplies 2 Registers to Operators Room and Abandoned ductwork above XG Computer Room, (at least 1 supply uncapped and open above dropped ceiling) RHC5 is currently held closed by having main air applied directly to the valve RHC5 could be re-enabled through installation of a pneumatic Thermostat locate in the Operators Room Since the Trunk line from AC2 is mostly blanked off above the Computer Room Ceiling, a solution to the Operators Area would be a re-route of this ductwork.
