Foreign Material Management Its a lot more than just foreign material exclusion (FME)
Foreign Material Any material that by: u Quantity or nature, and u Location Was not accommodated in the design
Programmatic Involvement In Consequential Nuclear Power Events u Reactivity management (Chernobyl, SL-1, Windscale) u Foreign material management (FMM)
Famous FMM Events u TMI-2 ~ LOCA (water in an air system) u Salem-2 ~ destructive turbine overspeed (particulates in control oil) u Salem-2 ~ anticipated transient without scram (wrong lubricant hardened and froze RTB) u Cook ~ regulatory shutdown (fibrous material in containment) u LaSalle service water (injection of sealant in service water tunnel) u Fermi-1 ~ core damage (component adrift in reactor)
Famous FMM Events u Point Beach (frazile ice) u Salem (river grass) u Davis-Besse (did not find source of FM in containment) u St. Lucie (jellyfish) u Columbia (foam fragments were FM)
Other FMM Events u Concorde u Titanic u Surgical Items left in patients (thousands) u Trojan Horse u Davis-Besse Sump Screens
Other FMM Experiences
Other FM Experiences (cont.)
FM Events u FM Damage u FM Near Misses (Intrusions +) u FMM Compromises u FMM Infractions and Deviations

Non-nuclear FM Events u Bhopal (water in MIC tank) u Herald of Free Enterprise (water) u ValuJet 592 (oxygen generators) u Chunnel Fire (burning cargo) u Concorde (loss of aircraft) u (box cutters)?
Your favorite FMM snafus... u Here u Elsewhere
Foreign Material ~ A Little Bit Goes A Long Way u Procedures can only prevent the repetition of the types of FMM events that have occurred u FMM education is necessary to prevent new types of FMM events
Foreign Material Management u Not just a signs and tags... u A way of doing business Foreign Material Exclusion Area
FMM Includes Control of FM production Control of FM access to buffer areas In FM buffer areas and danger areas: FM inventory control FM physical control FM removal before closeout FM exclusion Controlling the adverse side effects of FME measures
FMM Includes (cont.) Detecting FM compromises Detecting FM intrusions Control of intruded FM Removal of intruded FM Analyzing potential future effects of intruded FM Disposition of intruded FM Configuration tracking of intruded FM
Foreign Material Exclusion (FME) FME An important part of FMM
Control of Adverse Effects of Countermeasures FMM C/M are facility changes that must be controlled.
Response to Detected FM Response to Detected FM Stopping More FM Limitation of Transport Limitation of FM Effects Removal Assessment of Effects Documentation of FM Configuration
FMM ~ Design Factors u Good design may help filter out foreign material… or mitigate the consequences of a FMM event u But, dont rely on design factors alone to identify & prevent FMM problems
Some Places Where FMM Considerations Apply: u Work planning u Purchase orders u Design engineering u Chemistry controls u Radiation protection u ALARA u Pre-job briefings u Post-job walkdowns u Performance indicators u QC inspections u Receipt inspections u Alarm response instructions u Operator training u Management & tech. staff training u QA audit program u Severe weather walkdowns

Where Is Our Foreign Material Management Program? Is it narrowly focused on FME? Is it owned by a senior FMM Zealot? Does it include education as well as procedures? Do key managers support our FMM program as if their careers depend on it?
Where Is Our Foreign Material Management Program? (cont.) Does Operations support our FMM program as if the health and safety of the public depends on it? Can our corrective action database give a good picture of the status and adequacy of our FMM program performance? Are our senior managers good FMM role models? Do they walk the talk?
Where Is Our Foreign Material Management Program? (cont.) Does our Plant Operations Review Committee give our FMM program the attention it deserves? Has our executive level nuclear safety committee held a review of our FMM program performance? Has our independent oversight organization audited the status and adequacy of our FMM program performance?
