Westinghouse report PCS T2R 050, "Large Scale Test Data Evaluation, May 1995." The NRC
assessment was that with the exception of Figure 13, "Large scale PCS instrumentation Elevations" located on page 18, the material identified as~ proprietary would be withheld. De staff claimed that
' the identified figure was available to the public through other Westinghouse reports. In a telephone call with Ms. Jackson on January 29,1996, Westinghouse agreed that the identified figure was not 0- proprietary. Ms. Jackson indicated that the identified figure would be placed in the Public Document ._

Room. His letter provides written confirmation that the identified figure is not considered proprietary by Westinghouse. ,
