Examination regulations SVDB-NE14, Rev. 2 (18.2.1986), procedure for in-service inspection and supervision of nuclear power plant components subject to acceptance and belonging to safety categories 1-4. 3. Examination time schedule 3.1 The baseline inspection took place after the pressure testing of the primary system. For the pressurizer, which was already pressure tested on completion of fabrication, this means that the baseline inspection followed the second component pressure test. 3.2 The SVDB is invited in due course by the KKG to undertake supervision of the baseline and in-service Inspection test. Announcement of the test is issued with the relevant annual or outage inspection schedules. 4. Examination conditions 4.1 Examination of the pressurizer proceeds in accordance with the component examination programme tables. 4.2 In principle, the tests are conducted from the outside only, after removal of the insulation. Justification; After operation startup, a specific activity of 57 (gas) or 11 (water) Ci/m 3 is to be expected in the interior of the pressurizer. Exception : Visual Inspection of the internal plating and internal components in the area of the handhole nozzle. N.B. Owing to the built-in thermal skirt, internal inspection of the vessel wall is not possible from the manhole. 4.3 The test methods and specifications together with the test programme for the individual test areas can be seen from the component examination programme table. 4.4 The position and designation of the welds or examination zones can be seen from Annex 1. 91
