Response to Question 19 of reference 1 indicates that there is no' separate cation demineralizer for lithium and cesium while Table 3 of reference 2 indicates that there is. Explain this discrepancy.

2.

Response.to Question 14 of reference 1 indicates that the condensate demineralizer flow is 7,826,000 lb/hr which is approximately 70% of the steam flow rate indicated in response to Question 13 of reference 1.

Table 3 of reference 2 indicated 100% steam flow becomes condensate 3.

demineralizer flow.

Explain this discrepancy.

Indicate whether this purge frequency is based on operating experience or engineering judgement.

5.

For each of the plant release points, provide the following:

1.

Height above grade.

2.

Height above adjacent structures.

3.

Expected average temperature difference between gaseous effluents and ambient air, i
