Point Lepreau Instrument and Equipment Survivability Assessment During Severe Accident Conditions

Abstract

Instrument and equipment survivability during severe accidents has always been recognized as an important consideration in assessing response capability. However, events during the 2011 Fukushima Dai’ichi accident have placed renewed focus on ensuring critical instrument and equipment is capable of performing its function during a severe accident. NB Power has performed a survivability assessment following the COG JP-4426 methodology to evaluate the capability of equipment and instrumentation used during a severe accident to achieve a controlled, stable state after core damage under the consequential unique and harsh containment environment. This paper describes the evaluation, its results and planned next steps.
