SECTION 2 A
SUMMARY
2.1 TYPE A
SUMMARY
The recirculation spray cooler lap ring cracking condition that had been discovered during the Unit No. 1 CILRT was also found, to a lesser extent, on the Unit No. 2 coolers.
As reported by Vepco (see Reference 4), these cracks were caused by a crevice corrosion and stress corrosion cracking 7
condition.
The. repairs to the Unit No. 2 coolers were completed prior to the. October 1984 CILRT.
Vepco is currently evaluating potential modifications for the recirculation spray coolers to address this condition.
Pressurization for the CILRT was started at 2217 hours0.0257 days <br />0.616 hours <br />0.00367 weeks <br />8.435685e-4 months <br /> on October 12, 1984, and was completed at 1257 hours0.0145 days <br />0.349 hours <br />0.00208 weeks <br />4.782885e-4 months <br /> on October 13, 1984.
The "A" containment air recirculation' fan tripped at 1410 hours0.0163 days <br />0.392 hours <br />0.00233 weeks <br />5.36505e-4 months <br /> on October 13, 1984. The blades on these fans were adj usted to permit operation during the CILRT.
The containment air recirculation system would be isolated by the containment depressurization actuation signal when the containment pressure exceeds 10.psig. The procedural temperature stabilization criterica was achieved at 1800 hours0.0208 days <br />0.5 hours <br />0.00298 weeks <br />6.849e-4 months <br /> on October 13, 1984.
.For the first few hours after stabilization, the mass trend was very erratic.
The trend indicated a significant-leakage rate of approximately
^30 lba per hour, or just about twice the procedure acceptance criterion of
(,
0.75L
- A.
At. 0222 hours0.00257 days <br />0.0617 hours <br />3.670635e-4 weeks <br />8.4471e-5 months <br /> on October 14, 1984, a significant leak was observed in the containment air recirculation system chilled water piping.
An increasing water level in the chilled water makeup tank followed by venting air from the : supply and return header high points confirmed the leakage path.
As experienced on the recent North-Anna Unit No. 1 CILRT, the throttled chilled
-water _ flow for the ILRT lowered the system-pressure well below the containment pressure. This leakage path is not a credible design basis loss-of coolant accident leakage. path as z this system would be isolated.
It was running for - the CILRT_ to provide minimal' cooling flow to offset the fan.
. motor heat input and to stabilize containment air temperature.
By process of elimination, the "B"
air recirculation cooler uni _t-was identified as the major leakage path.
This cooler was isolated at: the penetration.
Air was still observed in the supply and return header piping
, after 1 the - isolation so - there were leaks,.although not as significant as those in the "B" Loop, in the other loop (s). The chilled water headers _were periodically vented thereaf ter, to _ prevent the system pumps ' from becoming air bound.
- The. CILRT was started. at 1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br /> on October 14,.1984, and was completed
-at 0240. hours on October 15, 1984. : The shorter duration test was done in
.accordance with the provisions of Reference 5.

2.2 LOCAL LEAKAGE RATE TESTS (TYPES B AND C)
The Local Leakage Rate Tests (LLRTs) of containment isolation valves and primary containment penetrations were conducted as required by station surveillance procedures since the Unit No. 2 preoperational Type A test performed in April 1979.
In accordance with Appendix J, 10CFR50, Paragraph V.B., data for the LLRTs are summarized in Section 4 of this report.

t 3.2 GENERAL TEST DESCRIPTION a{^'}
3.2.1 Initial Conditions In accordance with the North Anna Unit No. 2 CILRT Procedure 2-PT-61.1 (Reference 2), the following is a partial listing of the initial condi-tions completed and documented prior to containment pressurization:
a.
General inspection of the accessible interior and exterior surfaces of the containment structure was performed, b.
All test instrumentation calibrated or functionally verified within six months of the test.
c.
All required system valve lineups completed.
d.
Containment air recirculation system operating to maintain stable conditions, e.
Plant computers were operational and programmed for the CILRT.
f.
The official Log of Events was established.
g.
Site meteorological data was recorded during the performance of the test.
h.
All required Types B and C leakage testing complete c-reviewed by the Test Director.
.f x
3.2.2 Equipment and Instrumentation Pressurization of the containment was achieved by the utilization of ten air compressors.
Compressed air was piped through two after-coolers in parallel and then through a refrigerant air dryer. Ade-quate instrumentation and valving were installed to maintain control of the compressed air quality throughout -the pressurization sequence.
The total capacity of the pressurization system was slightly in excess of 10,000 cubic feet per minute.
The various containment parameters were monitored by the Leakage Monitoring System instrumentation.
The instrumentation (Attach-ment 3.2A), consisted of multiple resistance temperature detectors (RTDs), moisture dectectors, and two absolute pressure quartz mano-meters.
The general locations of the temperature and moisture sen-sors are shown in Attachments 3.2B and 3.2C.
A pair of rotometers were used to perform the superimposed leakage verification test. With the exception of these rotometers, all test instrumentation was monitored by the plant computer.
3.2.3 Data Acquisition System The data acquisition system used for the North Anna Unit No. 2 CILRT was
'~S the Westinghouse Prodac P250 process plant computer.
J B1-1426028-5097 3.2-1
For the CILRT, the P250 monitored the following instrumentation:
/
Type Scan Rate (sec) 18 RTDs 32 5 moisture detectors 32 2 quartz manometers 2
i The input to the C:ILRT program was a P250 calculated 10-minute average.
For the 0ctober 1984 CILRT, the P250 average program was modified to force an average at 10 minutes, independent of the number of accumulated scans.
The CILRT program performs sensor validity checks on the temperature, 4
moisture, and pressure sensors to identify any aberrant behavior.
If all sensors are trending within their CILRT, program limits, the program cal-culates weighted average dewpoint _ temperature, vapor pressure, weighted average containment temperature, and containment air mass.
i
[
LInstantaneous values of the CILRT instruments were recorded every 5 min-utes during the test period, using the P250 digital trend function on the operator's console.
During ;the Unit No.1 August 1984 CILRT, the RTD sensitivity was deter-mined to be causing some data scatter.
A three-fold improvement in the RTD sensitivity was realized by changing the range lof the computer bridge fg circuit.
This improvement was in place for the Unit No. 2 October 1984
'(vJ CILRT.
l-3.2.4 Data Resolution System Once the P250 has acquired the appropriate data, the reduced parameters -
are manually input into Vepco's Richmond Computer System for leakage rate
~
calculations.
For the North Anna Unit No ' 2 CILRT, both Mass Point and
. Total Time Analysis methods were used to determine the leakage rate (see Reference 5).
Absolute Method of Mass Point Analysis This method consists of calculating air. masses within the containment structure over the test period from pressure, temperature, and dewpoint observations. -The air masses are computed using the ideal gas law as follows:
Mass = 144V (P-Pv)
(Eq.1)
RT p,()
O B1-1426028-5097 3.2-2
Where:
l'
- M = air mass, Ibn I _- -
P = total pressure, psia s
Pv = vapor pressure, psia R = 53.35 ft-lbf/lbm*R (for air)
T = average containment temperature, *R V = containment free volume, 1.825 x 106 ft3 The leakage rate is then determined by plotting the air mass as a func-tion of time, using a least-squares fit to determine the slope, A'= da/dt.
.The leakage rate is expressed as a percentage of air mass lost in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or symbolically:
Leakage rate = (A/B) (-2400)
(Eq. 2)
Where A is the slope of the least-squares curve and B is the y intercept, the sign convention is such that the leakage out of containment is posi-tive and the units are in percent / day.
A 95-percent confidence interval is calculated using a Student's t dis-tribution.
The sum of the Mass Point Analysis leakage rate and the 95-
-percent confidence interval is the UCL-MP.
Absolute Method of Total Time Analysis This method consists of calculating a measured leakage rate.
The con-tainment air mass is computed using Equation 1.
The measured leakage O-rate at any time (t) is then determined by subtracting the mass -at the time (M ) from the initial mass (M ) and dividing by the initial mass.

The measured leakage rate is expressed as a percentage of the continment mass lost in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or symbolically:
Measured Leakage Rate = M. - M (2400)
(Eq. 3) 1-1 t
M (At) g
~
The sign convention is such that an outward leakage rate is positive and-
'the units are in percent / day.
~
The estimated leakage rate. is then determined by performing a linear least-squares fit of the measured leakage rate. values, as follows:
Estimated leakage rate = At + B (Eq. 4) where a is the slope and B is the y intercept of the least-squares line.
The'95 percent confidence interval is determined using a student's t dis-tribution.
The sum of the total time estimated leakage rate and the 95 percent confidence level is the UCL-TT.
