- 1. GENERAL This chapter describes acceptance and commissioning test programs and the maintenance program planned during use of the packaging.
- 2. ACCEPTANCE TEST PROGRAM 2.1. Examination of purchase and fabrication documents This examination covers all testing and inspection documents and reports related to procurement and manufacture, to ensure that the packaging has been manufactured in accordance with the specifications and quality assurance program (Chapter 8A in this Safety file) presented in this report.
This examination covers, specifically, the following points:
Conformity of materials with the specifications stated in Chapters 0 and 0A in this Safety file.
Dimensional compliance of the various components: dimensions must lie within the range of tolerances indicated on the design drawings appended to this report (see appendices 0-1 and 0A-1), with the exception of waivers or justified non-conformities shown on the as-built drawings, Compliant execution of procedures and operator qualifications. These procedures are related in particular to:
- welds, surface conditions (when specified) non-destructive tests (acceptance of equipment and check on the execution of some welds),
surface treatments, placement of the resin, placement of the lead.
Compliance of acceptance results with the criteria.
Qualification of inspectors.
2.2. Visual examination All accessible surfaces are visually examined, to check that they are free of dirt, grease, oil or any other contaminating deposit; surfaces are to be cleaned if necessary.
Internal and external surface conditions are examined to check that they comply with manufacturing specifications. Any failure to comply must be repaired or justified.
TN International Ref. DOS-18-011415-036-NPV Rev. 1.0 Page 4 / 12 NON PROPRIETARY VERSION 2.3. Handling point tests A load test shall be carried out on every handling point of the packaging. The method used should ensure a minimum force per handling point equal to 1.5 times its nominal load.
A dye penetration test of welds loaded during the test and trunnion bearing surfaces and fillets is carried out before and after each test. The load test is deemed to have been successful if there are no permanent deformations allowing for measurement uncertainty and if the dye-penetration test is satisfactory (white dye penetration criterion).
2.4. Hydraulic Test The test pressure is 11 bars gauge.
Criterion: no leak, no deformation of the closing system and the containment.
2.5. Containment leaktest The leak-tightness of the packaging containment system is verified by measuring leak-tightness levels for the:
lid inner seal orifice cover inner seals, welds on the containment system The test is deemed to be satisfactory if:
A. the total leakage rate is less than 3.5 x 105 Pa.m3.s-1 SLR.
B. the total leakage rate through containment welds is less than 1.10 x 107 Pa.m3.s-1 SLR.
2.6. Check on wood moisture content It is checked that the moisture content of the wood does not exceed the value specified in chapter 0 at the time that it is put into place in the shock absorbing cover.
2.7. Radiological homogeneity inspection The uniformity of radiation shielding shall be tested by gamma radiography. This test shall identify zones with the least radiation shielding.
TN International Ref. DOS-18-011415-036-NPV Rev. 1.0 Page 5 / 12 NON PROPRIETARY VERSION 2.8. Thermal test The purpose of this test is to verify the heat dissipation characteristics of the package.
The power distributed in basket compartments is equal to 8 kW. The packaging together with its shock absorbing cover or equivalent thermal protection and with or without one of its baskets is placed in the normal transport position. Packaging and shock absorbing cover meltable plugs are removed.
The power and the temperatures are recorded during the temperature rise and during thermal equilibrium, which is assumed to be reached after 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> of continuous heating.
This test is made on the first manufactured packaging or on a packaging from the first series manufactured.
2.9. Packaging correct operation tests The purpose of these tests is to check that the various components of the packaging can be assembled without hang-up or abnormal friction, and that the packaging is ready for use. These tests apply to the following points:
placement of the basket, placement of seals in their grooves installation and removal of closing systems installation and removal of the shock absorbing cover, line-up and operating test of the orifice cover handling tool line-up and operating test of the drain system, packaging drying test, packaging handling tests.
2.10. Basket correct operation tests Gauge insertion and extraction tests to verify the flow area inside compartments corresponding to the basket used.
2.11. Correct operation tests of the MTR-52S and MTR-52SV2 basket canisters Test for opening and closing of transport plugs and plugs for handling of canisters with the appropriate tool. Special attention shall be paid to ensure that there is no seizure during closing/opening.
Test for canister insertion into compartments 4 and 9 of the MTR-52S and MTR-52SV2 baskets to check the external cross-section of the canisters.
TN International Ref. DOS-18-011415-036-NPV Rev. 1.0 Page 6 / 12 NON PROPRIETARY VERSION Insertion of a gauge with an 83 x 83 mm2 cross-section to check the canister minimum internal cross-section.
2.12. Marking Regulatory identification plates shall be placed on the packaging after the examinations, checks and tests have been done, if they are all satisfactory.
2.13. Weighing All new packagings shall be weighed at the end of manufacturing starting from January 2015. The mass of the following components shall be checked:
each packaging with its top shock absorbing cover and without any internal
- fittings, each internal fitting.
- 3. MAINTENANCE PROGRAM For inspections with a frequency defined both by a number of cycles and a duration, the packaging shall be subjected to this inspection before the imposed number of cycles, and:
prior to the expiration of this duration, or after expiration of this duration if the packaging is not in transport, but before the next
- loading, the duration and intervals start the last time this test was carried out.
Tables 7A.1, 7A.2 and 7A.3 present the program of verifications, tests and replacement of critical components to be applied during use of the packaging. The intervals specified in this table are specific to each component and not to the packaging.
All packagings with one or more components not satisfying the criteria specified in the maintenance program (see Tables 7A.1, 7A.2 and 7A.3) shall be withdrawn from service until the appropriate corrective action can be applied.
