RE: OpE Input for Friday, May I Here is what I have pieced together concerning Millstone EDGs and Oyster Creek tritium. Any thoughts/comments?
Oyster Creek - Search for Source of Tritiated Leakage There are three buried pipe lines that Exelon considers on critical path to restart. 1 6" aluminum pipe is in service at 125 psi and no leakage has been observed. 2 additional 30 foot sections of Carbon Steel pipe (8" and 10") are in the process of being replaced and tested to insure integrity. 3 other additional pipe sections are not critical to restart. 1 line has been tested, 1 line is being excavated for examination, and 1 line (Condensate Transfer Bldg (CTB) floor drain) has been plugged.
Exelon is preparing to desludge and inspect the Condensate Storage Tank, including UST of tank bottom, by divers early next week. The question has been posed to Exelon to provide its bases and rationale for proceeding with startup without knowing the status of the CST, given that the highest ground water concentration noted during the investigation was from MW-51 which is located about 7' from the tank, down gradient relative to ground water (i.e., 6.05 million pCi/I). It is expected that Exelon's basis and rationale to be discussed on 5/1.
Currently, Exelon is planning startup 3:00 am on 5/2.
All affected environmental wells have been sampled. Expect results to be reported today. Well sampling plan is expected to be provided for review.
