RSICC CODE PACKAGE PSR-520

1. NAME AND TITLE

COMPASS 1.0.0: Computerization of MARSSIM for Planning and Assessing Site Surveys.

2. CONTRIBUTOR

U. S. Nuclear Regulatory Commission, Washington, D.C. and Oak Ridge Institute of Science and Energy, Oak Ridge, Tennesee.

3. CODING LANGUAGE AND COMPUTER

Visual Basic; Pentium (P00520PC58600).

4. NATURE OF THE PROBLEM SOLVED

The COMPASS Version 1.0.0 software was designed to facilitate the use of MARSSIM (Multi-Agency Radiation Survey and Site Investigation Manual) and guide the user into making informed decisions in designing final status radiological surveys. COMPASS also simplifies the application of the statistical tests by performing the statistical calculations and providing prospective power curves that help in determining what level of confidence the user is willing to accept for a particular number of measurements or samples for a survey unit. After performing the final status survey, COMPASS assess the data for comparison to the release criteria.

5. METHOD OF SOLUTION

COMPASS facilitates the use of MARSSIM and helps in making informed radiological survey decisions. The MARSSIM provides information on planning, conducting, evaluating, and documenting building and surface soil final status radiological surveys for demonstrating compliance with dose or risk-based regulations or standards. The MARSSIM is a multi-agency consensus document that was developed collaboratively by four Federal agencies having authority and control over radioactive materials: Department of Defense (DOD), Department of Energy (DOE), Environmental Protection Agency (EPA), and Nuclear Regulatory Commission (NRC). The MARSSIM's objective is to describe a consistent approach for building and surface soil final status surveys to meet established dose or risk-based release criteria, while at the same time encouraging an effective use of resources.

6. RESTRICTIONS OR LIMITATIONS

None.

7. TYPICAL RUNNING TIME COMPASS is an interactive program requiring seconds to process a request.

8. COMPUTER HARDWARE REQUIREMENTS

A Pentium 166 mHZ or higher is required with 32 MB RAM. A monitor with 600 x 800 or better screen resolution is also required.

9. COMPUTER SOFTWARE REQUIREMENTS

Windows 95, 98, NT 4.0 or 2000 is required along with Internet Explorer 4.0 or higher. The executable program is distributed, but no Visual Basic source files are included.
