The Surry nuclear power plant is located in Gravel Neck in Surry County , after which it was named, in the southeast of the US state Virginia on the south bank of the James River across from historic Jamestown or Williamsburg , 45 miles northwest of Norfolk and 17 miles northwest of Newport News . A canal is used to draw water from the James River. The area of ​​the power plant is 840 hectares. The nuclear power plant is similar in appearance and design to its sister plant North Anna . The four blocks of Surry and North Anna combined produce about a third of the electricity needed in Virginia.

Reactors

Four blocks were planned for the plant, but only two reactors were completed.

Block 1 and 2

Construction of the two reactors began on June 25, 1968. The first unit was synchronized with the power grid on July 4, 1972, and the second unit was first synchronized with the grid on March 10, 1973. Unit 1 went into commercial operation on December 22 1972 on, Block 2 followed on May 1, 1973. The architect for both reactors was Stone & Webster .

The two completed and operational blocks are pressurized water reactors from Westinghouse , each with three circuits. The reactors have a gross output of 838  MW each with a net output of 788 MW each. 400,000 average households can be supplied with electricity from the Surry nuclear power plant. In 2007 the capacity factor was 88.5% for Unit 1 and 101.2% for Unit 2.

In December 2016 it became known that Surry was also affected by the Creusot Forge scandal over falsified certificates. Parts of the lid of the reactor pressure vessel in Unit 1 come from the contaminated Areva subsidiary.

Block 3 and 4

Units Surry 3 and Surry 4 were also planned as pressurized water reactors, but compared to Units 1 and 2 with a higher projected gross electrical output of 919 MW (net output 859 MW, thermal output 2631 MW). Construction on both units began on January 1, 1974 and was canceled on March 1, 1977, around two years before the meltdown in Three Mile Island .

Generation costs

The two nuclear power plants, North Anna and Surry, were the two with the lowest generation costs out of 27 nuclear power plants in the USA between 2010 and 2012. They are given as 16.05 USD per MWh for North Anna and 17.38 USD per MWh for Surry.

Operating license

In the USA, the Nuclear Regulatory Commission (NRC) grants an operating license for a nuclear power plant for a period of up to 40 years. The 40 year period was originally based on the fixed asset depreciation period . The Atomic Energy Act of 1954 allows the operating license to be extended (even several times) by 20 years at a time.

The original operating license for Unit 1 was issued on May 25, 1972 by the NRC. It was extended on March 20, 2003 to May 25, 2032. The original permit for Block 2 was granted on January 29, 1973. It was extended on March 20, 2003 to January 29, 2033.

According to world nuclear news , Dominion Energy Virginia informed the NRC as early as 2015 that it was aiming for a further renewal of the operating license for the two units in 2019. Submitting a letter of intent is a prerequisite for the NRC to plan its manpower requirements for the license renewal process.

Data of the reactor blocks

The Surry nuclear power plant has two units in operation , another two units have been discarded:
