Features of KKS
 Uniform
identification of all types of power
stations and processes
 Capacity and detail for identification of all
systems
 Interdisciplinary applicability
 Non-language Based
 Application in computer processing
GB KKNPP QA
KKS do not contain rules on;
 Combination
of code with other
identification systems
 Methods of marking (like: in control rooms,
labeling of components and identification
of documents.
 Open text abbreviations
 Identification of redundancies
GB KKNPP QA
Type of codes

KKS has three different type of codes

1.Process-related code.
• Process related identification of systems and items of
equipment according to their functions in mechanical, civil,
electrical, C&I engineering.

2.Point of installation code
• Identification of points of installation of electrical and control
instrumentation devices in installation units. (cabinets,
panels, consoles etc..)

3.Location code
• Identification of locations in structure, on floors and in rooms
and also of fire areas and topographical stipulations (surface
area grid).

General conditions
-Numbering increases towards the flow
direction
-Numbering starts anew, if one of the
preceding code element changes
-Assigned numerical code characters shall
not be changed in the process of designing
-All leading zeros must be written
-Numbering logic can be different for different
part of the project.
General conditions (contd..)
-Sector 0 is for power unit or common station
installations
-Power unit is coded with numbers starting
from ‘1’
-Common station installations are coded with
‘0’.
 Code

The coding shall have space between sectors
in one, two or three lines,
e.g.:

+ UJA02 R003
GB KKNPP QA
Reserve codes may be applied upon
agreement with ASE and VGB Technical
committee (Germany):
If code remains unambiguous, sectors of
process related code in the ‘( )’ can be
omitted
GB KKNPP QA
The code F0 is applied for similar systems or
structures only
For designation of assignment for normal operation
systems and safety trains, Arabic numerals from 0 to
4 in F0 sector of KKS code are used in algorithm of
protections and interlocks
In the numerical code FN Numbering from
00 to 99 are used.
In the numerical code AN is applied for
assigning number to a structure. The biggest
number is 999.
GB KKNPP QA
During numbering of code group AN code R
shall be always available.
The numbering shall be plotted in Cartesian
coordinates.
For shafts and rooms that includes several
elevations, a three digit group coding is used.
3NN - transport shafts.
4NN – cable shafts
5NN – staircases
6NN - elevators
7NN – Reactor cavities.
