Shippingport reactor

Although the Westinghouse s PWR Shippingport reactor was the first LW R to generate electricity in the U.S., GE s BWR Dresden 1 reactor followed within a year. Operating power reactors range from 600 to 1,200 MWe (million watts of electric power). Since the thermodynamic efficiency is -33%, the thermal heat production is 1,800 to 3,600 MWt. Both types of reactor operate at about the same temperature (-bOOT),... 

A countercurrent HDEHP extraction process was used at Hanford in the late 1960s as part of the processing sequence for recovering and purifying 1 kg of Am and 50 g of Cm from irradiated Shippingport reactor fuel [50].

The idea of taking care of the RPV s as whole units became interesting and positive experiences was gained from the decommissioning of the Shippingport reactor. 

In Western countries, moreover, it was required that the whole refrigeration primary circuit should be located completely inside the containment, so that, even in the case of a complete rupture of the largest primary system pipe, all the escaped fluid would be confined in the containment envelope. The design pressure of the containment for water reactors (starting with the Shippingport, Pa, reactor, moderated and cooled by pressurized water) was derived on the basis of the assumption of the complete release of the primary water. 

Generation I (1950—1970)—experimental and prototype reactors The first power reactor generation was introduced during the period 1950—1970 and included early prototype reactors such as Shippingport, Dresden, and Fermi I in the United States. 

The pressurized-light-water reactor constructed at Shippingport employed ordinary water as both moderator and coolant and was pressurized to keep the coolant stream from boiling. The reactor coolant... 

Of the other three first-round projects, the proposal of the Yankee Atomic Electric Company to build a 175-megawatt electric pressurized-water reactor at Rowe, Massachusetts proceeded most smoothly. Shippingport, then imder construction, also was a pressurized-water reactor, but Yankee Atomic s concept, like Shippingport a Westinghouse reactor, was different because it operated at lower pressures. Delay over a disagreement about the nature of the AEC research md development to be conducted under the proposal hampered the signing of a contract imtil June 1956. Construction went almost on sdiedule and Yankee Atomic began operation in 1960. 

AEC and Duquesne Light Company negotiated agreement to construct jointly a pressurized-water reactor demonstration facility at Shippingport, Pennsylvania.

It is expected that power reactors such as that now under construction at Shippingport, Pennsylvania, will rely more upon the philosophy of containment than isolation as a means of protecting the public against the consequence of an improbable accident, but in each case there will be a reasonable distance...
