Obninsk Nuclear Plant Connects to Grid

Overview

What happened

Obninsk Nuclear Power Plant connected to the power grid as the world's first grid-connected nuclear reactor, marking a historic milestone in nuclear energy production.

Date

June 27, 1954

Location

Obninsk, Kaluga Oblast, Soviet Union, approximately 110 km southwest of Moscow, in a region with access to the Moscow River.

Key people

Lev Kotchetkov, Igor Kurchatov, and other prominent Soviet scientists played crucial roles in the plant's development and operation.

Outcome

The plant generated 5 megawatts of electricity, demonstrating the feasibility of nuclear power for industrial use and informing future reactor designs.

Why it matters

Obninsk Nuclear Power Plant's success paved the way for widespread adoption of nuclear energy, driving innovation and experimentation in the field.

What was Obninsk Nuclear Plant Connects to Grid?

Obninsk Nuclear Power Plant was built in the "Science City" of Obninsk, Kaluga Oblast, about 110 km (68 mi) southwest of Moscow, Soviet Union. Connected to the power grid in June 1954, Obninsk was the first grid-connected nuclear power plant in the world, i.e. the first nuclear reactor that produced electricity industrially, albeit at small scale. It was located at the Institute of Physics and Power Engineering. The plant is also known as APS-1 Obninsk. It remained in operation between 1954 and 2002. Its production of electricity for the grid ceased in 2002; thereafter it functioned as a research and isotope production plant only.

Obninsk Nuclear Plant Connects to Grid is tied to June 27, 1954. Key people connected to the event include Lev Kotchetkov.
