calc reviews using GOTHIC Dave and Nasser, The purpose of this e-mail is to bring to your attention a few points regarding GOTHIC. Since you review GOTHIC work from time to time, I hope this will be helpful for future reference.
- 1. The current GOTHIC version that appears in the Software Catalog is 6.0 (or 6.0a). Any other version of GOTHIC Is not qualified per Entergy SOA (I do not know the rules applicable to VY yet). This does not mean the newer versions will give erroneous answers, it only means we are stuck with the old version due to some unreasonable SQA requirements. We are trying to fix this. But for now, we should be sure to use the correct version.
- 2. GOTHIC 6.Oa has a number of errors. Most of these errors are not applicable to the models we routinely use. However, some may be applicable. The calculation should be reviewed with respect to these errors if the models susceptible to such errors are used in the calculation. The error reports, and the
guidance as to what should be reviewed at a minimum is available on the Web.

Transient & Thermal Hydraulics -> GOTHIC Software Control Plan... -> Excel Sheet for list of errors...
Also the calculation preparers should remember to send me Attachment 3 of the Software Control Plan whenever a calculation using GOTHIC is completed the latest.
