Operators at the Susquehanna nuclear power plant in Luzerne County near Berwick, Pa., briefly declared an “unusual event” Sunday, Sept. 15, as a result of water leaking inside a room in the plant's Unit 2 reactor building. The unit was shut down at the time of the declaration.

An unusual event is the lowest of the four emergency classifications established by the U.S. Nuclear Regulatory Commission for nuclear power plants. The event had no effect on public safety and required no public action.

The plant declared the unusual event at 11:38 a.m. after operators received indications of the water leak. They responded quickly to stop the leak, which was contained in one room. The plant is designed to contain water leaks to the room where they occur.

The unusual event declaration was ended at 3:52 p.m.

Unit 2 was shut down early Saturday, Sept. 14, for an inspection of the unit's turbine blades. It remains safely shut down.

"We have traced the cause of the water leak to a valve on one of the plant's multiple cooling systems. Other cooling systems were operational throughout the event. In keeping with our philosophy of operating the plant safely and conservatively, we will conduct a full investigation of this incident and make any necessary changes to be sure it does not recur," said Timothy S. Rausch, senior vice president and Chief Nuclear Officer for PPL Susquehanna. 

In accordance with plant procedures, local and state emergency management agencies were notified of the situation.

Unit 1 at the plant continues to run safely at full power.

The Susquehanna plant, located in Luzerne County about seven miles north of Berwick, is owned jointly by PPL Susquehanna LLC and Allegheny Electric Cooperative Inc. and is operated by PPL Susquehanna. More information is available at www.pplsusquehanna.com.

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
