Diablo Canyon 1) MIDAS with a home built front end for auto polling of plant and met data - our current version is terrain influenced model that utilizes a singe met input from the site - our new MIDAS is a wind field model, scheduled for go live this week, utilizes met data from 7 region specific towers surrounding the plant that alters the plume by 1/R2 as the plume approached the met region boundary.
2) We have been using MIDAS as a terrain specific influence model since 1995 - work on changing to a wind filed model has been in the works for a little over a year\ 3) Our County Air Pollution Control District, and to some degree, California OES have not been satisfied with the terrain specific model since it did not adequately address onshore ocean breeze affects on plume migration at certain areas 6 to 8 miles to the north and south of the plant Curt Hansen EP Coordinator - Dose Assessment 805-801-8185 ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Beckham, Bob Sent: Tuesday, June 21, 2011 9:39 AM To: [email protected] Subject: Powernet: Dose Assessment Software Duke Energy would appreciate any information you would provide on the following questions: 1) What software dose your site/EOF use for off-site dose assessment to the public (e.g., RASCAL, RADDOSE, MIDAS, home grown, etc.)? 2) Has your site/company changed to a different software within the previous 2 years? 3) IF the answer to question 2 is yes, would you briefly state why the change was made?
