CCC-0503 MARINRAD.

1. NAME OR DESIGNATION OF PROGRAM:  MARINRAD.

3. DESCRIPTION OF PROGRAM OR FUNCTION

The program system MARINRAD evaluates the consequences from release of radioactive waste into the ocean. It consists of two programs: (1) MARRAD computes nuclide  concentration caused by ocean transport and generates food chain concentration factors; (2) MAROUT evaluates a pathway-to-man dose model, generates print reports, and produces graphic plots.

4. METHOD OF SOLUTION

The systems model is divided into three distinct parts:
- An Ocean Transport Model. The ocean is partitioned into an arbitrary number of sediment and water compartments. The model computes the concentration of each radionuclide released into the system in each compartment as a function of time ( MARRAD).
- A Steady-State Food-Chain Model. Stable element concentration factors are used to calculate radionuclide concentrations in compartment biota. A food-chain model computes concentration factors for biota that prey on compartment biotra but do not reside in that  compartment (MARRAD).
- A Pathway-to-Man Model. Doses and health effects are calculated for all pathways that lead to exposure of man. These include ingestion of aquatic biota, external exposure to contaminated water  or sediments, inhalation of airborne spray or shore sediments, and several additional miscellaneous pathways. Doses to aquatic biota are also calculated (MAROUT).

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM:

6. TYPICAL RUNNING TIME:

The test case of MARRAD included in this package has been tested by NEA-DB on a CDC CYBER 740 computer in 737 seconds of  CPU time. The plotting capability MAROUT could not be tested, since  it uses the proprietary software DISSPLA which was not available at  NEA-DB.

11. MACHINE REQUIREMENTS:

To run the test case of MARRAD included in this package on a CDC CYBER 740 120,000 (octal) words of CM were required.

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED:

NOS2.5.1 664/650 (CDC CYBER 740) with compiler FTN5.1+650.
