INTERNATIONAL WORKSHOP ON CABLE AGING Darrell Murdock Division of Engineering Office of Nuclear Regulatory Research 301-415-1591 1
INTERNATIONAL WORKSHOP ON CABLE AGING OUTLINE
- 1. STATE OF KNOWLEDGE ELECTRICAL CONDITION MONITORING METHODS CABLE AGING RESEARCH GAPS
- 2. ONGOING RESEARCH NRCs ONGOING CABLE AGING PROJECT TEST RESULTS
- 3. OPERATING EXPERIENCE AND LONG-TERM OPERATION
- 4. INTERNATIONAL PLATFORM TO DISCUSS AND SHARE RESEARCH 2
INTERNATIONAL WORKSHOP ON CABLE AGING STATE OF KNOWLEDGE
- 1. CONDITION MONITORING METHODS (ELECTRICAL)
FURTHER RESEARCH IS NEEDED TO DETERMINE WHICH ELECTRICAL CONDITION MONITORING METHODS ARE CAPABLE OF TRACKING LOCAL AND/OR GLOBAL AGING
- REDUCE AMBIGUITY ON THE CAPABILITIES OF ELECTRICAL CONDITION MONITORING METHODS
- DETERMINE THE STRENGTH AND LIMITATIONS OF EACH ELECTRICAL CONDITION MONITORING METHOD
- INCREASE THE USE OF ELECTRICAL MONITORING METHODS OR NON-DESTRUCTIVE EXAMINATION 3
INTERNATIONAL WORKSHOP ON CABLE AGING STATE OF KNOWLEDGE
- 2. CABLE AGING ACCELERATED AGING RESEARCH GAPS
- SYNERGISTIC EFFECTS
- DETERMINE WHETHER OR NOT PERFORMING CONCURRENT AGING IS MORE CONSERVATIVE THAN SEQUENTIAL AGING
- INVERSE TEMPERATURE EFFECTS
- CERTAIN POLYMERS MAY DEGRADE FASTER AT CONSTANT DOSE RATE AT LOWER TEMPERATURE
- DIFFUSION LIMITED OXIDATION
- LACK OF OR LOWER THAN NORMAL LEVELS OF OXYGEN DIFUSSING TO THE INTERIOR PORTION OF THE CABLE
- REDUCE OXYDATION REACTIONS IN THE INTERIOR PORTION OF THE CABLE
- ACTIVATION ENERGY CALCULATION
- CONFIRM THAT THE MATERIAL ACTIVATION ENERGY DOES NOT DECREASE AS YOU EXTRAPOLATE FROM AGING TEMPERATURE TO ENVIRONMENTAL TEMPERATURE (NON-ARRHENIUS BEHAVIOR) 4

CONDITION MONITORING METHODS ASSESSED THE CABLES CONCURRENT THERMAL AND RADIATION AGING SHIP THE CABLE MANDRELS TO THE CONTRACTOR HIRED TO PERFORM THE LOSS-OF-COOLANT TEST 37
INTERNATIONAL WORKSHOP ON CABLE AGING DEVELOPMENT OF AN INTERNATIONAL PLATFORM WHERE RESEARCH IS DISCUSSED AND SHARED PURPOSE ADVANCE THE COMMON UNDERSTANDING OF CABLE AGING RELATED ISSUES WITH THE INTERNATIONAL STAKEHOLDERS POTENTIAL BENEFITS:
- FACILITATE INTERNATIONAL RESEARCH COORDINATION
- DECREASE DUPLICATION OF RESEARCH
- BETTER LEVERAGE RESOURCES INTENDED FOR RESEARCH
- PROMOTES COLLABORATION ON RESEARCH ACTIVITIES AND TECHNICAL DISCUSSIONS LEAD INSTITUTION
- NRC LED INITIATIVE
