"Big Science" Descriptor : Nuclear reactor research 



Description of Facility/Instrument : ZPPR Is a split table critical 

 facility designed for study of the physics of nuclear power 

 breeder systems. Its matrix Is made up of two 14xl4x5-foot 

 assemblies of matrix tubes mounted on separate steel tables. 

 Its output power Is less than 100 watts. It simulates com- 

 mercial reactor cores of 1,000 megawatts (electric). 



Date of Construction : 1968, criticality was achieved In 1969 



Construction Cost ; Original : $ 20 million (including fuel) 



1984 $$ : $170 million (including fuel)
