220.127.116.11 The effect of this failure on the system.
18.104.22.168 Assignment of risk assessment values for severity and probability.
22.214.171.124 Recommended corrective action.
126.96.36.199 Effect of the recommended action
2.1.1 This FMEA is intended to cover the RHIC cryogenic distribution system and
2.2 SYSTEMS AND COMPONENTS FOR ANALYSIS
2.2.1 The broad categories that will be included in this study are as follows:
188.8.131.52 The cold helium distribution system associated with the ring magnets (valve boxes,
transfer lines, etc.)
2.3 COMPONENTS REVIEWED
2.3.1 Types of components that are covered in this study include: valves, relief valves, sensors,
filters, switches, gauges, interlocks, etc.
2.4 SYSTEMS OR SUBSYSTEMS NOT COVERED
2.4.1 Systems that are not a direct part of the Cryogenic System, i.e. magnet power supplies,
quench protection devices, etc. will be subjected to an F.M.E.A., by others. The F.M.E.A. of
these "other" systems is outside the scope of this F.M.E.A.
3.1 - INTRODUCTION
3.1.1 To properly prepare an F.M.E.A. that includes the effects on the process and the
potential hazards to personnel, we must systematically identify and analyze all of the possible
3.2 GENERAL PROCEDURE FOR ANALYSIS
3.2.1 Identify the major systems and subsystems that in an event of failure will greatly affect
the operation of the cryogenic system or could present a hazardous situation to personnel.
Here’s what’s next.
