. - RSC Approval:5/2598 SEn5 ANNUAL THERMAL POWER CAUBRATION CALCULATION SHEET

1. Water level before power run (rneasured from the top of the tar.k). L=1 cm

2. Two sets of thermocouple readings taken before the power run.

TC#0 TC#1 TC#2 TC#3

._ Reading 1 Sum au readings and divide by 8. T=t *C

3. Time when power run was started (decimal hours) t=

i

4. Power meter readingo during the run % Pows = %

Unear Power = kW Log Power = kW

5. Time when the reactor was scrammed (decimal hours) 1" 2

6. Water level aher power run L=

2 cm

7. Two sets of thermocouple readings taken after the power run.

TC#0 TC#1 TC#2 TC#3

.,, . Reading 1 Sum au readings and divide by 8 T=2 *C

8. Vj = (731.52 L 1) 4.2895 x Id Vj = cm3 .

9. Vj = (731.52 L )2 4.2895 x 104 V=

2 cm3

10. Mt = V /(apoeirc t volume at TI )* vt - My = grams

11. M2* V /(apoeircvolume 2 at T2) V2 " M=

2 grams

12. M Mj M2

13. 3 Oevap = (M)(2.003 x 10 ) 4 (4.184)(M)(T 2IT ). O, yap = Joules

14. Ocap"(M 21 T ' MjT )(4.184)1 Ocap = }oulos

15. 3 time = sec time = (12* 1 )(3.6 x 10 )

16. Power = (Ocap + Owap)/ time Power = kW

17. Power meter caibration required 7 (if yes, use Form NEL-013.)
