Customer ServiceThis paper recommends adding quarterly inspections to the battery maintenance program of the Hualong nuclear power plant to more effectively monitor the status of non-indicating batteries, to maximize battery life, prevent avoidable failures and reduce premature replacement.
Customer ServiceSince rechargeable batteries serve as a backup source of electricity in power plants, their correctness is very important. Even a short-term outage can lead to catastrophic consequences. For these reasons, special attention should be paid to the maintenance of stationary batteries.
Customer ServiceUnexpected power failures, e.g., triggered by a natural hazard event or equipment failure, can cause a loss of containment of a dangerous substance. When power interruptions and restarts are deliberate, they need to be planned in advance to avoid inadvertently causing release of a dangerous substance.

Customer ServiceBattery hazards can have serious consequences in the form of explosions or fires which can be quantified in terms of blast and thermal loads, respectively. These consequences have the potential to threaten buildings, equipment, and most importantly people.
Batteries can fail in several ways, often resulting in fires, explosions and/or the release of toxic gases. One common failure mode is thermal abuse, where batteries are operated outside of their designed temperature range, as provided by the manufacturer.
The accident reports indicated that power failures on hazardous sites have resulted in 21 fatalities and over 9500 injuries worldwide since 1981, as well as significant property damage and production loss from resulting fires and explosions. The impacts from one power failure can be devastating.
Battery cells can fail in several ways resulting from abusive operation, physical damage, or cell design, material, or manufacturing defects to name a few. Li-ion batteries deteriorate over time from charge/discharge cycling, resulting in a drop in the cell’s ability to hold a charge.
These articles explain the background of Lithium-ion battery systems, key issues concerning the types of failure, and some guidance on how to identify the cause(s) of the failures. Failure can occur for a number of external reasons including physical damage and exposure to external heat, which can lead to thermal runaway.
However, the potential for power failures may also contribute to chemical accident risk on hazardous sites. Unexpected power failures, e.g., triggered by a natural hazard event or equipment failure, can cause a loss of containment of a dangerous substance.
