FW: H-3 sources IPEC_RL_Comments_1.xls Jim, At todays Spent Fuel Pool status meeting I inquired about our plans to verify that the Unit 1 south curtain drain was unblocked and functioning and also the Unit 2 containment footer drain system and segregation of its outfall for sampling at manhole 5. I was told that a feasibility study is in progress to determine robotics entry points.From: Croulet, Donald Sent: Tuesday, December 20, 2005 9:46 AM To: 'James Noggle'
