ANSI/ISA-67.02.01-1999 - Nuclear Safety-Related Instrument Sensing Line
Piping and Tubing Standard for Use in Nuclear Power Plants
General reference,
softbound, 44pp.
$65.00
Establishes the applicable code requirements and code boundaries for the design and installation of instrument sensing lines interconnecting nuclear safety-related power plant processes with both nuclear safety-related and non-nuclear safety-related instrumentation.
Scope:
This Standard covers design, protection, and installation of nuclear safety-related
instrument-sensing lines and sampling lines for nuclear power plants.
The Standard covers the pressure boundary requirements for sensing lines
up to and including one inch (25.4 mm) outside diameter or three-quarter
inch nominal pipe (19 mm). The boundaries of this Standard for instrument-sensing
lines span from the root valve/piping class change, up to but not including,
the manufacturer-supplied instrument connection. The boundaries of this
Standard for sampling lines span from the process tap to the upstream
side of the sample panel, bulkhead fitting, or analyzer shutoff valve,
and include in-line sample probes.
Purpose:
This Standard establishes the applicable code requirements and code boundaries
for the design and installation of instrument-sensing lines interconnecting
nuclear safety-related power plant processes with both nuclear safety-related
and nonnuclear safety-related instrumentation. This Standard also establishes
the applicable requirements and limits for the design and installation
of sample lines interconnecting nuclear safety-related power plant processes
with sampling instrumentation.
This Standard addresses the pressure boundary integrity of an instrument-sensing line and sampling line in accordance with the appropriate parts of Section III, Boiler and Pressure Vessel Code, American Society of Mechanical Engineers (ASME) or American National Standards Institute (ANSI) B31.1, as applicable, and the assurance that the safety function of the nuclear safety-related instruments and process sampling is available.
