1. Alleaedly, durina hot functional tests in 1983. CPSES loaded fuel. ,

operated the reactor to generate steam in order to perform the hot  !

functional tests. As a result of this unauthorized event workers removina coatinos inside containment were exposed to radiation. l Texas Utilities Electric Co, CPSES received a low power operating '

license on February 8, 1990. CPSES commenced initial fuel loading on February 9,1990, and completed fuel loading on February 14, 1990.

Initial criticality was achieved on April 3,1990 at 2:42 p.m.  !

2. Alleaedly, tritium alarms have been soundina as material is released into Souaw Creek Reservoir and other release areas. You believe from information you have received that CPSES released acoroximately 1800 I DCi/l durina the 2nd auarter 1991.  ;

CPSES does not have tritium alarms that sound when tritium is released 1 from CPSES. In order to analyze a sample for tritium, a liquid sample must be obtained, mixed with a chemical solution referred to as a ,

" cocktail", and placed into a liquid scintillation counter where the low t energy light pulses are counted. The counting results are equated to an ,

activity of tritium per unit volume. l The total activity of tritium released from CPSES during the 2nd quarter  !

1991 was 160 curies, the total volume of water released from CPSES was .

2.85E+10 liters. CPSES reported a release of 5.62E-06 microcuries per milliliter for tritium which is approximately 0.187% of the regulatory limits that are allowed for tritium in water in an unrestricted area.

If you convert the 5.62E-06 microcuries per milliliter reported by CPSES to picocuries per liter, using the following conversions: 1,000,000 picocuries - 1 microcurie; and 1,000 milliliters - 1 liter; the result is 5,620 picaturies per liter which equates to 5.62E-6 microcuries per milliliter reported by CPSES for the 2nd quarter 1991, r
