STEAM GENERATOR PRESSURE TEST 1

December 1,1972 Robinson File No. 2-0-9-a jd-J -71 Date of Test OBJECTIVE

,1. Establish a 1900 psi differential pressure between the primary and secondary systems for purpose of a pressure test.

INITI AL CONDITIONS

1. Reactor is in hot shutdown condition with reactor coolant pumps running

. as required.

r

2. All control and shutdown rods are inserted. 9/

f

3. Pressurizer heaters are in " auto" control. M f
4. Pressurizer power operated relief valves are set up for normal operation. M f

S. Pressurizer continuous spray valves are ','open" and pressurizer control spray valves are in " auto" control. M

6. Reactor makeup in " auto" control with boron adjusted to

/

makeup at reactor coolant system concentration. M f

7. Letdown is maxicum for purification of the primary system i) water. ,

11. Feedwater is being supplied through the feedwater bypass valves.
12. Primary coolant has been sampled for iodine and tritium, and leak rate of each S/G has been determined. M f

PPICAUTIONS

1. Primary system pressure should not exceed the normal operating pressure of 2235 psig.
2. Calibrated gauges are to be utilized on the primary and secondary system to determine pressure.

~

3. Only authorized personnel are to be allowed inside the

/

containment vesscl.

f

4. Insure a positive labyrinth seal as required for the reactor ecolant pumps. "

^

5. The limitation of a 200 F delta temperature between the pressurizer and the primary system is not applicable (Permanent change) . ,

6. If test exceeds seventeen hours duration it will be necessary to compensate with boron addition for Xe decay to maintain shutdown margin. )h5 7 . Do not exceed a cooldown or heatup rate of 50 F. per hour.
8. During cooldown, monitor nuclear instrumentation and plot a 1/H curve.
9. Do not utilize the secondary system power operated relief valves unless it becomes necessary to prevent the safetics from lifting.
10. Sample and determine boron concentration of the primary system at .

30 minute intervals or as requested by the shift foreman.

11. Pressurizer sprays should not be used if the spray fluid is more than 320 F below the pressurizer temperature.
12. All normal precautions for cooldown and heatup remain in effect unless specifically altered by this procedure.

\

1. Borate to the bcron concentration as specified in the attached shutdown margin calculations for the test period. Shu+.dewn margin calculated for
17. shutdown at 2000F.

.. /

2. Begin cooldewn from hot shutdown conditions utilizing the turbine and/or condenser steam dumps to dissipate energy. Pressurizer autonatic systems should r: air.tain no load level and pressure in the pressurizer. Do not exceed a cooldown rate of 50 F / hour._

7-

3. When Tavg decreases to $h3 F. go to the "37 pass Tavg Interlock" position on the steam dunp centrols.

/

h. Block the High Steam Flow, Low Steam Pressure / Low Tavg safety injection signal at Tavg of 5h3 F.

/

M

5. Continue cooldown until a differential pressure of 1900 psi exists between the primary syste:n (primary system pressure deterained by PI LOh & h05) and the secondary syste t (secondary pressure determined from test gauges on the three steam lines).

/

M NOTE: Insure that a 1900 psi differential does exist. Secondary pressure indication shculd be 33h psig with primary pressure at 2235 psig.

6. Maintain the required pressure differential until the data required on the attached data sheet is obtained.
