SUBJECT:

ORNL LETTER REPORT ON PTS The enclosed letter report from ORNL is forwarded for your infomation and use on A-49. This is the last report planned under the ORNL research project on pressurized themal shock integration. The report addresses the differences in the results of ORNL's three plant-specific PTS studies in order to distinguish differences due to plant desion features from differences due to improvements in analysis methods. These oisterences are sumarized in section 8 of the report including tables 8.1 and 8.2.
