Thanks.

Where is MW-55?

'Thanks.

Re: Oyster Creek sample results Todd, Here's the latest:

I

The Condensate Storage Tank inspection work by divers ha* been completed. No indications of leakage have been identified.

Exelon plans to excavate and examine a 1-inch minimum flow line associated with the condensate tank. This would be part of the company's efforts to complete the examination of buried piping considered to be a possible source of the groundwater contamination. The excavation of that line may take place later this week. Inspection of the pipe wold include removing its coating and subjecting the line to ultrasonic testing.

The company's root cause analysis is expected to be completed about mid-month. It is expected to include an analysis of

'the corrosion mechanism/cause that led to the holes identified earlier in the 8-inch and 10-inch buried pipes associated with condensate storage tank system. To date, Exelon has not identified any other source of the groundwater contamination.

Here are the latest well sample results:

MW-50: 3.22 million picocuries per liter of tritium MW-51: 3.72 million MW-52: .MDA (minimum detectable activity)

MW-53: Close to .MDA MW-54: 9,950 MW-55: 1.2 million MW-15; 905,000 These sanples are from 5/27.

Daily samples taken from the intake, discharge and Route 9 bridge areas have not indicated any tritium concentrations above MDA.

NRC Region staff specialists and our Resident Inspectors at Oyster Creek continue to closely follow these issues. We will review Exelon's root cause evaluation once it is complete.

RE: Oyster Creek sample results Neil:

Anything new re: the search for the source(s) of the tritium at Oyster Creek?

Have any new sources of tritium been found and what are the latest well readings?

Thanks.

Oyster Creek sample results

Todd, Here are the latest well sample results for Oyster Creek (from 5/6/09):

Well MW15KIA -- 5.3 million picocuries per liter of tritium Well MW-50 -- 2.9 million Well MW-51 -- 4.5 million Well MW-52 -- Below minimum detectable activity Well MW-53 -- 15,100 Well MW-54 -- 9,500 All of these wells are in the vicinity of the condensate storage tank and associated buried piping.

The attached graphic might help you to better visualize where the condenser fits in as far as plant operation.
