ASME N510:2007 pdf free download.Testing of Nuclear Air Treatment Systems.
5.1 Purpose
A visual inspection of the air treatment system, as specified by the test program, shall be made in conjunction with each test series to identify visual deficiencies prior to commencing tests. In addition, this inspection may be used to verily that the system design and construction are in accordance with ASME N509,
5.2 Summary of Method
Visual inspection shall be performed under a combination of background light plus supplementary light that provides adequate illumination of the surface to be inspected.
5.3 Prerequisites
Construction, modification, and/or repairs shall be completed to the extent of supporting the test series.
5.4 Apparatus (Equipment)
Supplementary light providing adequate illumination of the surface to be inspected is required.
5.5 Procedure
Visual inspections shall be conducted in accordance with ASME N511. Whenever “unacceptable” is used, it is intended to mean any damage or condition that would impair the ability of the item to perform its function.
5.6 Acceptance Criteria
Inspection results are acceptable when there are no indications of improper installation, physical damage, structural distress, or degradation that would impair the ability of the system to perform its intended function.
5.7 Report
A written report shall be prepared in accordance with section 14. Items identified as unacceptable should be further documented in the comment section of the test report to assist the owner in preparation of corrective action.
6 DUCT AND HOUSING LEAK TEST
6.1 Purpose
These tests are used to verify the leak tightness of the housings and ducts.
6.2 Summary of Method
The ductwork or housing is pressurized to determine leak tightness. The leakage shall be determined using either the pressure decay or constant pressure method.
NOTE: The pressure decay method may not be adequate to identhy bypass Leakage if the duct leakage acceptance criterion allows a higher leak rate for the duct than the damper criterion. When the challenge aerosol test is used, the duct size and espected leakage range must be considered for the purpose of estintating aerosol transit time from the damper boundary to the dowitrram test port location
11.3 Prerequisites
For a challenge aerosol or gas test, the injection and sample points shall be qualified per ASME AG-I.
11.4 Apparatus
11.4.1 For a challenge aerosol or gas leak test, the equipment shall be listed in section 9 or 10, respectively
11.4.2 For a pressure decay leak test, the equipment shall be listed in section 6.
11.5 Procedure
11.5.1 For a challenge aerosol or gas leak test, the procedure shall be in accordance with section 9 or 10, respectively.
11.5.2 For a pressure decay leak test, the procedure shall be in accordance with section 6.
11.6 Acceptance Criteria
The leakage shall be within the criteria specified in the test program or owner’s design specifications.
NOTE: The leakage value for bypass shall be added to the leak rate re%ult measured in section 9 or 10, or both, if th bypass is not challenged when challenging the filter banks.
11.7 Report
A written report shall be prepared in accordance with section 14.
12 AIR HEATER PERFORMANCE TEST
12.1 Purpose
This test is used to verify that the nuclear air treatment system air heater performance, at the design flow rate (±10%), meets the test program or owner’s design specifications.
12.2 Summary of Method
Power-on electrical (voltage and amperage measurements) and mechanical tests shall be performed to verify correct operation and condition of the air heater.
12.3 Prerequisites
Visual inspection of the heater shall be completed.
12.4 Apparatus
(a) clamp-on ammeter and voltmeter
(b) temperature-indicating device
13.5 Procedure
The adsorbent sample(s) shall be tested in accordance with ASME N511.
13.6 Acceptance CriterIa
Adsorbent test criteria shall be as stated in the test program or owner’s design specifications.
13.7 Report
A written repurt shall be prepared in accordance with section 14.
14 REPORTS
A written report shall be provided to document the in-service testing performed. The report shall conform to the facility’s test program and contain, as a minimum, the following:
(a) the system name, test/inspection procedure(s) used, date of test, results, and the user’s signature
(b) identification of the instruments, equipment, tools, and documents to the extent that they, or their equivalent, can be identified for future examinations
(C) observations and dimensional checks specified by the respective test data and any reports developed during the inspection and testing
(d) conclusions and recommendations by visual examinations and testing personnel
(e) reference to previous reporis, if this report is for reinspection and testing.
