Periodic Checks
Services for Power Plants
Containers that require checks are subject to various
checking periods according to the operational safety
regulations in force. Due to the relatively long checking
intervals, it is generally not profitable for a company operating a power plant to carry out periodic checks using
its own personnel. Technical service providers are used
for this who regularly carry out periodic checks and
thus have a great deal of experience.
Voith Industrial Services is an experienced specialist in the area
of periodic checks for nuclear and conventional power plants.
We take over the following activities for you in carrying out your
periodic checks.

External and Internal Checks
Planning, Coordination and documentation
The external check includes:
• Evaluating the external condition of system parts in
pressure systems that are in need of monitoring
• Checking the safety-related equipment (presence,
condition and functionality)
In order to adhere to the schedule of an inspection, a detailed
timetable is drawn up in advance. Coordination of documents
relevant to comissioning is of enormous importance. Without
the documentation being finally concluded, a system cannot
be put back into operation. Our services here include:
• Drawing up planning lists (on the basis of checking dates
and work clearance lists)
• Coordination of all sub-sections
• Pressure check release
• Carrying out checks after clearance
• Documentation of checks with the applicable technical
inspection body
The internal check includes:
• Checking the pressurized cladding
• Checking compliance of the set-up with the specifications
in the checking documents
• Opening, cleaning and closing of containers and pressure
anks
• Execution together with the applicable technical inspection
body
Strength Checks
Processing of Findings
The condition of pressure systems in need of monitoring is
checked before comissioning and periodically checked during
the operating phase.
Strength checks are usually static pressure checks for
demonstrating the appropriate safety as compared to the permissible operating pressure. The strength check includes the
following steps:
• Water samples in the case of non-radioactive systems
• Production of pressure sample connection for the area that
is pressurized
• Coordination and execution with the applicable technical
inspection body
• Documentation
Application of checking procedures (VT, PT, FEP, among
others) in an inspection can show findings that should be
promptly repaired so as not to endanger the course of an
inspection. In doing so, provision of tools is important. Voith
provides the following services:
• Elimination of findings after coordination with the operating
company
• On-site measurement
• Carrying out visual checks
Surface Crack Detection
Surface crack detections evaluate the quality of manufacturing
and repair of welding seams and the reproducibility of periodic
checks at operationally stressed welding seams. The following
steps are to be carried out:
• Visual check before the non-destructive check
• Preparation, coordination and execution with the
applicable
technical inspection body
• Cleaning of the checkpoints
• Documentation
• Production of final condition through conservation
