fyi. I know we were expecting this report; sounds like it will be soon.

John I wanted to give you a heads up that we will be issuing to the NRC our final ground water report this week (most likely Friday). The first few paragraphs from the letter are copied below, so you can get a flavor of the letter.

We are making sure our stakeholders are aware of this. You will be receiving a CD rom of the final report.

Entergy Nuclear Operations, Inc. (Entergy) has completed a comprehensive ground water investigation at the Indian Point Energy Center (IPEC).

This investigation was conducted from October 2005 through October 2007 as a result of an apparent spent fuel pool (SFP) leak at Unit 2 which were discovered during construction activities within the Unit 2 Fuel Storage Building (FSB) as previously reported. During the ensuing investigation it also became apparent that the previously known Unit 1 leak was migrating beyond collection points thought to contain it.

The scope of this investigation included all three (3) reactor units and all areas of the site where credible potential sources of leakage could exist. The investigation has identified the sources of leaking radioactivity responsible for the radioactive contaminants that have been found in ground water at the IPEC site. The affected ground water regime has been characterized and modeled to determine the fate of leaked contaminants in the environment, identified the sources of the leakage and determined the radiological impacts that result from this leakage. As a result, Entergy has begun implementation of a long term ground water monitoring program and initiated a remediation program.

Detailed results of the investigation are provided in the enclosed ground water investigation report, and summarized below.

The sources of ground water contamination have been traced back to leakage that originates from two separate structures, the Unit 2 fuel building and the Unit 1 fuel building. This conclusion is based on the 1

radionuclide and chemical characteristics of the sources, ground water flow patterns, and the concentration gradients within the plumes. No other sources of leakage to ground water were identified as contributing to these ground water plumes.
