Re: Millstone 3 tests

Warren, Please feel free to post the GOTHIC Millstone-3 report in the public document room and/or on ADAMS.

GOTHIC has been used for the gas transport analysis at many plants using an approach that gives conservative estimates for the void at the pump intake and for pressure pulse analysis.

On behalf of our clients and other GOTHIC users, we are very interested in addressing any questions or concerns that you may have regarding these applications. We would be happy to meet with you and your staff to discuss GOTHIC, the validation for gas transport and the methods we've developed for plant analysis.

If you think this would be helpful, please suggest some dates and location and we will do our best to accommodate you.

I'm working with our regional people to establish a working line of communication so that we can get together and I can get better calibrated. In the meantime, Section 1.4 of ML102300053 covers our position with respect to GOTHIC. We periodically update this as we obtain new information. I anticipate the next update will be in October.
