VGB POWERTECH 11 (2019)

Digital nuclear security level DCS main and auxiliary data distribution based on NASPIC platform VGB PowerTech 11 l 2019
based on NASPIC platform, the other security
level platforms mentioned above do
not have TU transmission stations, which
will reduce the number of cabinets, but
there is a risk that the load of the main processor
is large and the response time is relatively
long.
Conclusions
Through the in-depth analysis and research
of the security level DCS architecture,
the data transmission mode of the
main and auxiliary data shunting is proposed,
which gives priority to ensuring the
safe and reliable processing and transmission
of the main data directly related to the
security function. The distribution of auxiliary
function data in TU station effectively
reduces the load of main function data
transmission channels, improves the realtime
and reliability of the system, and ensures
the safe and reliable operation of nuclear
power plant. The distribution technology
of main and auxiliary data has been
successfully applied to many projects, and
has achieved good engineering application
results.

Summary
This VGB Standard VGB-S-610, “Structural Design of Cooling Towers” constitutes the joint basis – together with VGB-R 135e,
“Planning of Cooling Towers”, and VGB-R 612e, “Protection Measures on Reinforced Concrete Cooling Towers and Chimneys
against Operational and Environmental Impacts” – for the civil engineering-related planning including design, construction and
approval as well as for the construction of cooling tower facilities built from reinforced concrete. It is based on more than 50 years
of experience in the construction of cooling towers gained by plant and structural design engineers, by construction companies,
accredited review engineers and owners. In addition, Guideline VGB-R 613e, “Code of Practice for Life Cycle Management of
Reinforced Concrete Cooling Towers at Power Plants”, presents notes on in-process inspection and maintenance.
The VGB Standard was thoroughly revised and restructured compared with the last edition, VGB-R 610e of 2010, chiefly in order
to increase its application and ac-ceptance by potential users outside Germany. To this end its structure was modified to make it
similar to the European standards by dividing into a generally valid and internationally oriented base part and a specific national,
i.e., German part. Different from the European standards, however, no national annex was created. Instead, for improved readability
a unified document was produced comprising the generally applicable base part and the location-specific part (on a grey
background) with German rules. For application outside Germany it is necessary to use the respective national rules and specifications
instead of the German rules.
New findings from continued engineering studies and feedback from practice have also necessitated modifications. In particular,
hybrid cooling towers and multi-cell cooling towers as now common cooling tower design variants have been included, in addition
to natural draught cooling towers.
This VGB Standard does not cover contractual arrangements with responsibilities for organisational workflows. These are to be defined
separately by the contracting par-ties. Users are requested to inform the VGB Office of their experience with the appli-cation
of this VGB Standard and any sources of possible misinterpretation or short-falls in presentation, and to make suggestions for improvements.
These may be tak-en as a basis for future additions or amendments.
This VGB Standard VGB-S-610e, “Structural Design of Cooling Towers”, supersedes VGB Guideline VGB-R 610e of 2010 with the
same name.
