Subject:

Byron Station Units 1 & 2 Initial Test Program Results Containment Ventilation System NRC Docket Nos. 50-454/50-455 ~ f Reference (a): 2-6-87 S.A. Varga letter-to D.L. Farrar

Dear Mr. Murley:

As requested in reference (a), a further assessment of Byron Unit 1 Included is a discussion RCFC low speed fan performance has been completed. on the use of fan motor data to determine actual fan flow in lieu of a direct airflow measurement. During Retest R-152 at Byron Station the airflows for the Unit 1 RCFC fans were taken at the riser stacks because flow readings at the fans could not be taken. Attachment A provides a list of the uncorrected RCFC stack airflow data for Unit 1. To evaluate'the flow,at the fans themselves, This l and as such at the RCFC coils, the fan motor electrical data was used. data was converted to horsepower and when the fan horsepower was plotted on the fan curve the flowrate at the fan was determined. As a double check of this method, the measured fan pressure was This taken and used to determine the fan flowrate using the fan curve. method compared to the first method determined that both indirect flowrate methods were in correlation. Since this was the case, and-the electrical data is more accurate, this was used as the basis for the fan performance evaluation for Unit 1. Attachment B lists this test data and provides a description of how to determine the fan flowrate.. i In order to demonstrate the validity of using fan motor data to . determine fan flowrate, the Byron Unit 2 RCFC Testing and Balancing (TAB)- data was analyzed. During the Unit 2. TAB, a direct airflow measurement at the fan was taken along with the fan motor' data. The results are summarized As can be seen, there is a good correlation between the in Attachment C. fan motor data and the fan flowrate measured directly. We thus feel that the use of the fan motor data to evaluate the Unit.1 RCFC fan (and coil) ~ flowrate is valid and shows that our FSAR commitments have been satisfied. -l k' i g l B706180001 870529 PDR ADOCK 05000454 P PDR g t

B/B-FSAR AMENDMENT 43 SEPTEMBER '1983 mode. f Fan cooler heat removal performance is shown in Figure 6.2-17and G.2 -11c. l 7p Inadvertent Spray Actuation In the event of inadvertent spray, the containment.would depressurize until the temperature of the air was approximately the temperature of the spray. A calculation was performed to calculate the maximum outside to inside pressure differential. The following initial conditions were assumed: a. The containment'is initially at 1200 F, which maximizes the temperature differential between the containment atmosphere and the spray,J which is at a temperature of 35* F. b. The containment is at 14.7 psia. c. The relative humidity is at a maximum value of 100%. As the air temperature is reduced, the partial pressure of the air decreases from 13.009 to 11.103 psi. The steam partial pressure decreases from 1.691 to 0.117 psi as the spray cools-the atmosphere. Thus a containment-pressure of 11.22 psia is produced, causing a differential pressure of 3.48 psi across the containment shell. Accident Chronology For the double-ended pump suction, double-ended hot. leg, and double ended. cold leg loss-of-coolant accidents, the major events and their times of occurrence are shown in Tables 6.2-6 through 6.2-8. Table 6.2-9 presents the accident chronology for the limiting steamline rupture.

6. 2.1. 2.1 Design Basis Loop Compartment, Upper Pressurizer Cubicles, and Steamline Pipe Chase Reference 6 provides the basis for break' locations, types, a'nd areas.

The design-basis break for the subcompartments is a circumferential, double-ended guillotine rupture of high-pressure system pipe which yields the maximum' mass and energy release rates. Since the circumferential double-ended guillotine rupture of a system pipe is the design basis, no credit is taken for-limiting break ' reas due-to pipe restraints. a Reactor-Cavity Annulus The most severe line break in the reactor cavity is a circum-ferential cold leg break at the nozzle safe-end weld.
