1. NAME AND TITLE

PCDOSE: Radioactive Dose Assessment and NRC Verification of Licensee Dose Calculation.

2. CONTRIBUTORS

Idaho National Engineering Laboratory, Idaho Falls, Idaho.

3. CODING LANGUAGE AND COMPUTER

Lotus 123 macro language; IBM PC's and compatibles (C00630/IBMPC/00).

4. NATURE OF PROBLEM SOLVED

PCDOSE was developed for the NRC to perform calculations to determine radioactive dose due to the annual averaged offsite release of liquid and gaseous effluent by U.S commercial nuclear power facilities. Using NRC approved dose assessment methodologies, it acts as an inspector's tool for verifying the compliance of the facility's dose assessment software. PCDOSE duplicates the calculations of the GASPAR II mainframe code as well as calculations using the methodologices of Reg. Guide 1.109 Rev. 1 and NUREG-0133 by optional choice.

5. METHOD OF SOLUTION

PCDOSE uses spreadsheet models of the dose assessment mathematical equations. The results appear in table format.

6. RESTRICTIONS OR LIMITATIONS

PCDOSE requires Lotus 1-2-3 software.

7. TYPICAL RUNNING TIME

A typical gas particulate problem took 20 seconds to execute on an IBM PS/2 Model 70 running MS-DOS 6.2. Faster execution times are obviously expected on faster machines. The liquid and noble gas modules ran at five seconds and two seconds respectively for maximum cases. Problem setup time is dependent on the amount of input data required. Maximum size gas particulate problems may require setup times of up to 30 minutes, liquid problems may require setup times of up to 15 minutes, and noble gas problems may require up to 5 minutes to setup.

8. COMPUTER HARDWARE REQUIREMENTS

Requirements include an IBM PC or compatible. For maximum operation, a minimum of 400K available conventional memory, a Math coprocessor, and 2 MB of EMS memory are recommended. PCDOSE uses approximately 2.5 MB of disk space.

9. COMPUTER SOFTWARE REQUIREMENTS

Lotus 123 v2.01 or higher is required to use PCDOSE. PCDOSE was tested at RSIC using Lotus 123 v2.4.
