5.1.5 Components which have been repaired, replaced, or otherwise subjected to temporary or permanent modification shall be tested in accordance with I
procedures which are appropriate in view of the nature of the repair, replacement' or modification, and in view of the condition of the system.
5.1.6 All annual tests requiring the reactor to be shut down may be performd at the nearest scheduled shutdown, provided that the interval between tests does not exceed 16 months.
The interval between semi-annual tests shall not exceed 8 months.
5.1.7 Definitions applicable to Section 5.2.15 are as follows:
Channel Check:
A qualitative determination of acceptable operability by I
observation of channel behavior during operation. This determination shall i
include, where possible, comparison of the channel with other independent channels measuring the same variable.
Channel Test:
Injection of a simulated signal into the channel to verify its proper response including, where applicable, alarm and/or trip initiating action.
Channel Calibration:
Adjustment of channel output such that it responds, l
with acceptable range and accuracy, to known values of the parameter which the channel measures. Calibration shall encompass the entire channel, including equipment actuation, alarm, or trip.

5.2.1.2 Individual Leak-Detection Test (Type B and C Tests):
Type B and C tests shall be performed as follows:
(a) Type B Tests:
Leak-detection tests shall be performed at a pressure of at least 52 paig by using the soap-bubble technique (or other methods of equivalent sensitivity) or by determining the rate of pressure loss of pneumatically pressurized test chambers on the following containment components:

the electrical penetrations, i
the reactor build'ng spray valve shaft penetration, l
the freight door, the main steam line penetration, J
the feedwater line penetration, the heating steam line and condensate return penetration, the containment building airlocks, and the flanges of the ventilation system inlet and exhaust ducts.
Component Leak Surveillance System:
A leak surveillance system (i.e.,
continuous pressurization of individual containment components) that maintains a pressure not less than 52 psig at individual test chambers of containment penetrations and seals during normal reactor operation shall be acceptable in lieu of Type B tests for the components under such leak surveillance.
1 l
l (b) Type C Tests:
Containment isolation valve leak detection testing shall be conducted at a pressure of 52 psig.
l (c) Acceptance Criteria:
The combined leakage rate for all I
penetrations and valves subject to Type B and C teste shall be less than 60%
of the design leak rate at 0.1 percent per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> (d) Corrective Actions:
Leaks which cause the acceptance criteria of l
(c) to be exceeded shall be repaired and retested until the criteria is met.
Repairs of lesser leaks are optional.
l (c) Test Frequency:
Type B tests (except for air locks and electrical I
penetrations) shall be performed at intervals no greater than two years.
Air locks shall be tested at 4-month intervals.
The freight door shall be tested following each closure prior to plant startup.
Electrical penetrations shall be tested at intervals no greater than one year.
Type C tests shall be performed during each reactor shutdown for refueling, but in no case at I
intervals greater than two years.

l 5.2.1.5 Report of Test Results:
The leakage rate results of Type B and C l
tests that meet the acceptance criteria shall be reported in the applicable LACBWR operating report.
Leakage test results of Type B and C tests that fail to meet the acceptance criteria shall be reported in a separate summary that includes an analysis and interpretation of the test data, the least squares fit analysis of the test data, the instrumentation error analysis, and the structural conditions of the containment or components, if any, which contributed to the failure in meeting the acceptance criteria.
