SUhVEILLANCE PROCEDURE 6.3.6.1 RCIC TEST MODE SURVEILLANCE OPERATION i
- 1. PURPOSE A. To provide a detailed instruction for station personnel to check the reactor core isolation cooling (RCIC) pump flow rate and pressure.
II. DISCUSSION A. The RCIC pump flow controller, flow rate, and discharge pressure are verified during this test by using the RCIC system test flow path. Pump suction is from the emergency condensate storage tanks, through the RCIC pump, through the test flow line, and back to the emergency condensate storage tanks. If during this test low reactor water level (> -37") occurs, system initiation signal, the system will return to auto initiation lineup. , B. Surveillance Procedure 6.3.6.4, RCIC Turbine Test Potentiometer And Pump Operability, can be performed to check the operation of the test potentiometer if so desired. III. REFERENCE MATERIAL A. USAR.

IV. PREREOUISITES A. Instrument and service air system in operation. B. Emergency condensate storage tank level normal. C. Suppression pool level normal. D. RCIC area FCU available and in service (preferred). V. LIMITATIONS A. Surveillance Requirements - Technical Specification Sections 4.5.D.1.b.,
-4.5.D.1.d., 4.5.D.1.e., 4.5.G.1., 4.5.H., and 4.6.G. (IST).
- 1. RCIC subsystem testing shall be performed as follows:
- a. Pump operability is once/ month,
- b. Flow rate at
- 1000 psig steam pressure is once/3 months (will be done monthly).
- c. Flow rate at
- 150 psig steam pressure is once/ operating cycle.
- d. Discharge piping filled is once/ month,
- e. Unit coolers. operability checked during testing of the associ-ated pumps.
- 2. With the surveillance requirements of Technical Specifications Section 4.5.D. not performed at the required intervals due to reactor shutdown, a reactor startup may be conducted provided the appropriate surveillance is performed within 48 hours of achieving 150 psig reactor steam pressure.
B. Administrative Limits.
- 1. All discrepancies shall be recorded in the Shif t Supervisor's log.
'rocedure Number 6.3.6.1 Date n.4/ E5 Revision 15 Page 2 Of 6- Pages
- 2. Attachment "B" shall be used to record the test and filed as part of the station records.
- 3. All testing shall be coordinated with the Control Room Operator.
VI. PRECAUTIONS - A. Assure positive suction is available to the RCIC pump from the emergency condensate storage tank. B. During periods of standby status, the flow control transfer switch shall remain in the AUTO position and the flow controller shall remain set for 100% flow. C. During any controlled operation of the pump, monitor closely for unusual vibration, oil pressure, oil temperature, or other abnormal conditions. D. The turbine should not be started or operated with oil temperature < 60*F or > 160*F. E. The pump, turbine, and associated equipment must be free of all obstruc-tions and foreign material at all times. F. Do not over-pressurize the RCIC low pressure pipe in the test return line to the emergency condensate storage tanks. The manual return valve must be open before the RCIC system is placed in operation. G. Warm the RCIC steam supply line slowly when placing the system in service. H. During operation of the RCIC system, closely monitor the suppression pool temperatures and place the Suppression Pool Cooling Mode of the RHR system in operation, as necessary, to maintain the pool temperature
< 95'F (can go to 105'F during testing but must be returned to < 95*F within 24 hours).
I. Obse rve that the gland seal condenser condensate pump always' has a discharge path valved into operation or that the pump ' breaker is deenergized. J. Do not exceed the manufacturers recommended startup suction strainer differential pressure. . K. During the 150 lbs. reactor steam pressure pump test, insure that the rea-tor heatup/cooldown rates are not exceeded. VII. TEST EOUIPMENT A. Stopwatch.
