1.0 BACKGROUND

1.1 Heatup Event Exceeds 100'F/hr The River Bend vessel experienced a heatup of 119'T in a one hour period. November 30,1990. This heatup rate exceeds the design basis rate of 100'F/hr frots the stress reports and pressure temperature (P T) curves. The rate was specifically exceeded between 1630 and 1730 hours0.02 days <br />0.481 hours <br />0.00286 weeks <br />6.58265e-4 months <br /> from 213'T to 332'F. During that time, the vessel pressure increased from 0 psig to 88 psig.

1.2 Vessel Integrity Concerns To evaluate the River Bend i vessel integrity, the magnitude of stress, the offect on fatigue usage, and the question of brittle fracture need to be addressed. Brittle fracture is not a concern because the temperatures were nat close to the limits of the pressure. temperature curves, for this heatup event. The vessel pressure boundary and the recirculation and steam piping are evaluated for excessive heatup stress and fatigue impact. The 100'F/hr vessel heatup rate limit is not applicable to the fuel. The fuel related limits are contained in the Fuel Warranty Operating 1.imits section of Amendment 6 to the Fuel Fabrication Services Contract for the River Bt.nd Nuclear Power Plant, Unit 1. For internals, thermal stresses are small compared to stresses due to deadweight and flow (6P and vibration). The stresses at the low flow, low temperature condition with the 119'F/hr heatup are bounded by the 100% flow, normal operating temperature condition at the end of the 100'F/hr heatup.

11,

f 9 2.0 FOUR CAEH AWAf YnD APPLY TO ENTIH VEHil, t

Four specific cases are analyzed to demonstrate the effects of the heatup event. The results from these cases can be applied to the entire vessel.

Using the River Bend Unit 1 stress reports, the four areas used to bound the analysis include:

1.- TOP HEAD

2. STUD
3. SUPPORT SKIRT 4 FEEDWATER N0ZZLE The conclusions for the top head and feedwater nozzle apply to all pressure boundary components, including the recirculation system and steam piping.

2.1 Top Head Analysis The combined thermal and pressure stress from the 119'F/hr heatup is two to four times-less than the largest calculated stresses at the top head during the heatup event.1 For example at the most severe location for the top head, the 119'F/hr heatup stress value was 7.78 Ksi compared to the more limiting calculated stress - of 35.06 Kai at end of startup.

Even though the higher temperature increased the ' thermal contribution slightly, the low pressure decreased the values significantly resulting l' in a much lower combined heatup stress. The top head analysis (details l

in Appendix A) is typical of the reactor pressure vessel shell.

21

4 2.2 Stud Analysis The change in fatigue usage factor, due to the 119'F/hr heatup event, is determined to be an increase of 0.0005 for the studs.2 The one cycle fatigue usage factor increases from 0.0043 to 0.0048. The detailed stud analysis is in Appendix B.

2.3 Support Skirt Analysis The point analyzed for the support skirt had the highest usage factor I and is the most limiting location for the 119'F/hr heatup case. Using the calculated startup temperature 3 in the support skirt region and the corresponding stresses, the 119'F/hr heatup stress was 41.9 Ksi -

compared to the larger, more limiting calculated stress of $3.9 Kai at 450'F.4 Therefore, the excess heatup had an insignificant effect on the support skirt stresses. Detailed calculations and support skirt schematic are in Appendix C.

4 2,4 Feedwater Nossie Analysis i in the feedwater nozzle stress caport for the triple thermal sleeve , 5 the startup and shutdown cases were bounded by the feedwater heater bypass case. One cycle of heatup and cooldown associated with feedwater l heater bypass had a fatigue usage of 0.0000036. A normal heacup would be less than this amount, and the incremental usage due to the 19'F ,

exceedance of the heetup limit would be even less. Therefore,.the 119'F/hr heatup event had an insignificant fatigue impact on nozzles such as the feedwater nozzle. The analysis and feedwater nozzle schematic are in Appendix D.

4 L O._Ilg10P EVENT DM,E NOT VIOLATE P.T Ct'RVES The thermal effects were included in the pressure temperature (P.T) curve data 6 to reflect the excessive heatup rate of 119'F/hr. This higher temperature rate shif ts the two thermally dependent core beltline curves, the heatup/cooldovn curve (B') and core critical operation curve (C'), less than 2'r. Figure 3.4.6.1 1 illustrates the 8 ef fective full power years 100'r/hr River Bend 1 P.T curve. If a 2'F shift of curves B' and C' were included, it is clear that the vessel condition of 88 psig and 332'F would not violate the adjusted curves.
