STANDARD REVIEW PLAN o
OFFICE OF NUCLEAR REACTOR REGULATION P
SECTION 3.9.6 INSERVICE TESTING OF PUMPS AND VALVES REVIEW RESPONSIBILITIES Primary - Mechanical Engineering Branch (MEB)
Secondary - Reactor Systems Branch (R$8) 1.
AREAS OF REVIEW The HEB reviews the following areas of the applicant's safety analysis report (SAR) that cover the inservice testing of pumps and valves designated as Class 1. 2. or 3 under the Anerican Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (hereaf ter "the Code"). Section !!!:
1.
Inservice Testing of Pumps _
The descriptive information in the SAR covering the inservice test program for all a.
Code Class 1. 2. and 3 system pumps is reviewed. The Reactor Systems Branch veri-fles the code class designations for each listed pump and the completeness of the list.
b.
Reference values for testing for speed, pressure, flow rate, vibration, and bearing temperature at normal pump operating conditions are reviewed.
The pump test schedule, included in the plant technical specifications, is reviewed, c.
d.
The methods described in the SAR for measuring the reference values and inservice values for the pump parameters listed in I.1.b above are reviewed.
2.
Inservice Testing of Valves The descriptive information in the SAR covering the inservice test program of all a.
Code Class 1. 2. and 3 valves is reviewed. This review does not include those valves defined in !WV-1300 of Section XI of the Code. The Reactor Systems Branch verifles the code class designations for each listed valve and the completeness of the list, b.
The SAR test program, which includes preservice tests, valve replacement, valve repair and maintenance, indication of valve position, and inservice tests for all valve categories, is reviewed.

II. ACCEPTANCE CRIVERIA The acceptance criteria for the areas of review, described in 1 of this plan are as l
follows:
j l
1.
Intervice Testing of Pumps l
a.
The scope of the applicant's test program is acceptable if it is in agreement with j
IWP-1000 of Section XI of the Code. Since the pump test program is based on the detection of changes in the hydraulic and mechanical condition of a pump relative 4
to a reference test specified in IWP-3000, the establishment of a reference set of parameters and a consistent test method is a basic criterion of the program, b.
The pump test program is acceptable if it meets the requirements for establishing reference values and the periodic testing schedule of IWP-3000 of Section XI of the Code. The allowable ranges of inservice test quantities, corrective actions, and bearing temperature tests are established by IWP-3200 and IWP-4300. The pump test schedule in the plant technical specifications is required to comply with j
these rules.
c.
The test frequencies and durations in the plant technical specifications are acceptable if the provisions of IWP-3300 and IWP 3400 of Section XI of the Code are met. If a pump is normally operated more frequently than once a month, and at l
the reference conditions, it need not be specially tested. Otherwise, pumps must I
be tested each month during plant operation, and during shutdown periods if practical. The pumps must be run for at least five minutes under conditions as stable as the system permits. Bearing temperatures must be measured once a year for the duration specified in IWP-3410.
d.
The methods of measurement are acceptable if the test program meets the requirements of IWP-4100, 4200, 4300, 4400, and 4500 of Section XI of the Code with regard to instruments, pressure measurements, temperature measurements, rotational speed, and vibration measurements.
2.
Inservice Testino of Valves a.
To be acceptable, the SAR valve test list must contain all Code Class 1,2, and 3 valves except those used for operating convenience only, such as manual vent, drain, and test valves, and valves used for maintenance only. The SAR valve list must include a valve categorization which complies with the provisions of IWV-2110 of. -* ion XI of the Code. Each specific valve to be tested by the rules of l
Subss...on IWV is listed in the SAR by type, valve identification number, code class, and IWV 2110 valve category, b.
The valve test procedures in the plant technical specifications are acceptable if the provisions of IWV-3000 of Section XI of the Code are met with regard to pre-service and periodic inservice valve testing.
111. REVIEW PROCEDURES The reviewer will select and emphasize material fram the procedures described below as may be appropriate for a particular case. For each area of review, the following review procedures are followed:
3.9.6-2 11/24/75 1
l.
Inservice Testing of Pumps of The scope of the applicant's program is reviewed for agreement with II.l.a a.
this plan. The program is acceptable if a preservice test program is used to establish reference values. The periodic inservice program must verify the reference values within acceptable limits, of The pump test program procedures must agree with the requirements of II.l.b b.
this plan. The applicant must justify any exception to II.l.b.
The program is best presented in tabular form in the plant M chnical specifications, The inservice test frequencies and test dur,, ons in the plant technical c.
specifications are reviewed for agreement with II.l.c of this plan, d.
The test results described in the SAR are reviewed for agreement with II.l.d of this plan. The SAR need only provide the necessary information to permit a conclusion that the methods of measurement and the data acquisition system will provide the needed data. The reviewer does not approve or disapprove the instru-ments or methods proposed or used.
2.
Inservice Testing of Valves The SAR valve test list and valve category description are reviewed for agreement a.
with II.2.a of this plan, b.
The valve test program is acceptable if the procedures follow the rules of Section II.2.b of this plan for preservice and periodic inservice testing.
IV. EVALUATION FINDINGS The reviewer verifies that sufficient information is provided in accordance with the requirements of this review plan and that his evaluation supports conclusions of the following type, to be included in the staff's safety evaluation report:
"To ensure that all ASME Code Class 1, 2, and 3 pumps and valves will be in a state of operational readiness to perform necessary safety functions throughout the life of the plant, a test program is provided which includes baseline preservice testing and periodic inservice testing. The program provides for both functional testing of the components in the operating state and for visual inspection for leaks and other signs of distress.
"The applicant has stated that the inservice test program for all Code Class 1, 2, and 3 pumps and valves meets the requirements of the ASME Code,Section XI Subsections IWP and IWV, respectively.
" Compliance with these code requirements constitutes an acceptable basis for satisfying the applicable portions of General Design Criteria 37, 40, 43, and 46."
