Subject:
Pressuriser Spray Valve Operation
- 3 Gentlenen:
- i The Control Analysis section of Babcock & Wilcox has reviewed the differential temperature between the Pressurizer and the Reactor Coolant System to ensure that the spray actuation would not result in the design criteria being exceeded.
for the Pressurizer Spray and Pressurizer Surge Lines. Based upon this reviev, the current recommendation is:
Do rot aetuate the pressurizer spray valve during plant heatup unless,the(AT;between the pressurizer and the RCS id'less than or. equal to:250 F, unless required for plant safety.
This new limit should be observed for pressurizer spray valve operation and should be incorporated in Section 1.2 of DP 1101-01 for D1I-1.
Revised DP 1101-01 for DiI-2 already ine,1udes this new li=1t.
