A study of radioactive material releases from the gaseous and liquid effluent of the first Philippine Nuclear Power Plant (PNPP-1)

Radioactive material releases from the gaseous and liquid effluents of the first Philippine Nuclear Power Plant (PNPP-1) were determined using a modified PWR-GALE Code. This code is a computer program employing a mathematical model for ''source term'' calculations for pressurized water reactors. The input data utilized for source term calculations are based on the information gathered from the Preliminary Safety Analysis Report and the Environmental Report for the First Philippine Nuclear Power Plant. The computer output gives the annual release rates of the following: 1) noble gases, 2) radionuclides and radioactive materials in particulate form, 3) radionuclides other than noble gases, 4) corrosion and activation products, 5) fission products. The results obtained from the computer output were used to make a comparative analysis of the annual release rates and radionuclide concentrations with that of 10 CFR Part 20, to determine if the PNPP-1 has been adequately designed to reduce the radioactive releases to ''as low as is reasonably achievable.'' 20 refs.; 9 tabs.; 3 figs.
