these tanks were to be installed at the Hinkley Point B and three at the
Hunterston B nuclear powerplants. The system was to provide gaseous nitrogen
~t 700 pounds per square inch and 250° C for injection, as required,
into the reactors' coolant circuits. The gaseous nitrogen was to be obtained
by vaporizing the liquid nitrogen withdrawn from storage.54 
 U.S.S.R.—A large fertilizer trade deal with the U.S.S.R. was proposed
to Soviet officials by the chairman of Occidental Petroleum Corp.~,The proposal
called for Occidental to supply 1 million tons per year of superphosphoric
acid to the U.S.S.R. and to receive in return $150 million worth of urea
and ammonia.~~ 
 Construction work at the Nevinomysk combine was going ahead smoothly, and
nitric acid and ammonium nitrate units were being completed a year ahead
of the original completion date. Two dilute nitric acid units were onstream,
and a third unit was about to undergo trial runs. An am- 
89~ 
monium nitrate plant with a capacity of 680,000 tons per year was commissioned
during March, and an ammonia plant was expected to be onstream before yearend.56
Venezuela.—Venezolana del Nitrogen (Nitroven) was to supply urea fertilizer
to the People's Republic of China from its new complex at El Tablazo, Venezuela.
Two 900-ton-per-day ammonia plants and two 1,200-ton-per-day urea plants
were commissioned at El Tablazo during the year. In addition, a 600-ton-per-day
ammonia plant and 750-ton-per-day urea plant were started up at MorOn. Two
contracts were finalized with China for a supply of urea fertilizers worth
$23 million. Nitroven expected to capture a 10% share of the world market
for urea.~'
