Question: What was the 2010 population of the town just south of Portsmouth Gaseous Diffusion Plant in 2010?
Context: Tarrafal de São Nicolau is a town in the western part of the island of São Nicolau, Cape Verde.  Its 2010 population was 3,733 and home to more than a third of the municipal population, it is also home to about a quarter of the island's population and is the island's most populated place which is more populated than the island's main city (rarely as capital) Ribeira Brava.  It is situated on the west coast, 9 km southwest of Ribeira Brava and is connected with the main road (EN1-SN01) which is 53 km northeast.  It is the seat of the Tarrafal de São Nicolau Municipality, and the main port of the island.  the town and area are surrounded by mountains.  The port is the other that offers ferry services to other islands including São Vicente and Sal which connects to other islands including Santiago.  The town area covers the south of the municipality roughly a third and bordering up to about 700 meters above sea level in the north bordering Monte Gordo Natural Park, the municipal boundary is to the east.  For many years, the port is the island's most busiest, it was expanded before 1990 and completed in 1991, it is 137 meters long and fits for two boats, the water's depth ranges from 3 to 7 meters.  It is the only island that have two ports that are used for ferry services, it once had two that used it, the other was Sal. Piketon is a village in Pike County, Ohio, United States, along the Scioto River.  The village is best known for the uranium enrichment plant located there (one of only three such plants in the United States).  The population was 2,181 at the 2010 census.  Originally called Jefferson, it was the county seat of Pike County 1815–1845, when James Emmitt, a wealthy local entrepreneur, influenced removal of the county seat to Waverly, due to its closer proximity to the then new Ohio & Erie Canal.  Piketon is the location of the Pike County Fairgrounds and is served by the Scioto Valley School District. Somanya is a town and the capital of Yilo Krobo District, a district in the Eastern Region of south Ghana.  Somanya has a 2013 settlement population of 20,596 people.  Because the town itself is surrounded by a number of farming communities to the north of it, the use of the name Somanya actually encompasses a collection of smaller communities around a bigger one.  As a result, the 2010 Population and Housing Census conducted by the Government of Ghana put the population of Somanya at 87,847, representing 3.3 of the region's total population.  Males constitute 48.2 percent of the population while females represent 51.8 percent according Ghana Census Bureau.  The entire Krobo district is described as rural and Somanya is currently the municipal district center of the surrounding smaller towns.  With the capital of Ghana, Accra, rapidly expanding northwards, the traveling distance between Somanya and Accra is shrinking and now is around 30 miles. 596, originally named by the US intelligence agencies Chic-1, is the codename of the People's Republic of China's first nuclear weapons test, detonated on October 16, 1964, at the Lop Nur test site.  It was a uranium-235 implosion fission device made from weapons-grade uranium (U-235) enriched in a gaseous diffusion plant in Lanzhou.  The bomb had a yield of 22 kilotons, comparable to the Soviet Union's first nuclear bomb RDS-1 in 1949 and the American Fat Man bomb dropped on Nagasaki, Japan in 1945.  With the test, China became the fifth nuclear power.  This was the first of 45 total nuclear tests China has conducted to date, all of which occurred at the Lop Nur test site. The Portsmouth Gaseous Diffusion Plant is a facility located in Scioto Township, Pike County, Ohio, just south of Piketon, Ohio that previously produced enriched uranium, including weapons-grade uranium, for the United States Atomic Energy program and U.S. nuclear weapons program.  The plant is in shutdown status and is in preparation for decontamination and decommissioning (D&D), with some facilities overseen by the United States Enrichment Corporation, a subsidiary of USEC Incorporated, a publicly traded corporation (NYSE: USU).  The D&D work on the older facilities to prepare the site for future use is expected to continue through 2024 and is being conducted by Fluor-B&W Portsmouth LLC. K-25 was the codename given by the Manhattan Project during World War II for the project to produce enriched uranium for atomic bombs using the gaseous diffusion method.  Originally the codename for the product, over time it came to refer to the project, the production facility located at the Clinton Engineer Works in Oak Ridge, Tennessee, the main gaseous diffusion building, and ultimately the site.  When it was built in 1944, the four-story K-25 gaseous diffusion plant was the world's largest building, with over 1640000 sqft of floor space and a volume of 97500000 cuft . Happy Valley was a construction camp of trailer homes and hutments at the Clinton Engineer Works of the Manhattan Project in the 1940s.  It was located near the K-25 gaseous diffusion plant in Oak Ridge, Tennessee, to lessen travelling time for the seventeen thousand construction men working there. The Paducah Gaseous Diffusion Plant (PGDP) is a facility located in McCracken County, Kentucky, near Paducah, Kentucky that produced enriched uranium 1952–2013.  It is owned by the U.S. Department of Energy (DOE).  The PGDP was the only operating uranium enrichment facility in the United States in the period 2001–2010.  The Paducah plant produced low-enriched uranium, originally as feedstock for military reactors, weapons and later for nuclear power fuel. Orange Walk Town is the fourth largest town in the nation of Belize, with a population of about 13,400 (Official Release of the Main Findings of the 2010 Population and Housing Census).  It is the capital of the Orange Walk District.  Orange Walk Town is located on the left bank of the New River, 53 mi north of Belize City and 30 mi south of Corozal Town. Eurodif, which means "European Gaseous Diffusion Uranium Enrichment Consortium", is a subsidiary of the French company AREVA, which operates a uranium enrichment plant established at the Tricastin Nuclear Power Center in Pierrelatte in Drôme.  The nuclear site of Pierrelatte includes many nuclear installations, of which the largest are the Eurodif fuel factory and the Tricastin nuclear power station.
