Description

PRELIMINARY SCOPE OF WORK: 1. Radiological characterization of above and below grade piping. It is suspected that there is considerable residual radioactivity in the pipes associated with this drainage system, but the actual extent and levels of this contamination are unknown. The radiological constituents of potential concern (COPC) are 234U, 235U, 94Nb, 60Co, 137Cs, and 90Sr. Pipe openings range from two inches to three inches in diameter. Pipe diameters start 2 inches to 3 inches in diameter the openings and, through a series of transitions, progress to 6 inches when joining the main drainage line beneath the building. 2. Radiological characterization of ventilation ducting between Postmortem Cells and Basement Rooms 6 & 7. The two independent HEPA filtration systems were used to maintain negative pressure in the postmortem cell area while examinations and tests were preformed on the reactor fuel. When operational, air was drawn into inlet vents situated on the sides of each of the postmortem cells, through ducting formed into the concrete walls and ceilings, through a series of HEPA filters located in the basement mechanical room (Rooms 6 and 7), and out through the two small stack located on the east side of the building. Although not present, the mouth of the inlet vents are engineered for a prefilter that reduces the amount of contamination entering the ventilation system. The effectiveness of the prefilters is undeterminable, but recent surveys show negligible removable contamination and fixed contamination of approximately 20,000 dpm/100 cm2 ? (. The ventilation inlets and associated ducting needing characterization are 6 inch by 18 to 24 inch rectangular openings that penetrate strait down to the ceiling of the basement. The greatest length for such ducting is 12 feet. The COPC are the same as for the radiological drainage pipes. Method of characterization shall have the ability to identify all gamma emitting radionuclides between 100 KeV and 2 MeV and quantify the activity of each identified gamma emitting a radionuclide in each linear meter of pipe of ducting. A detail description of methods shall be provided to the Contractor 30 days in advance for proper development of work control documents. A detailed training plan will be developed to show compliance with required training. RADIOLOGICAL RELEASE, SURVEY, AND LICENSE REQUIREMENTS: 1. Subcontractor must provide the Contractor with a radiological survey of all equipment before transporting to the Nevada Test Site. Contractor?s Health Physics Department will verify that contamination levels are within current radiological control limits. 2. The Contractor will perform an initial radiological survey to verify radiological survey provided by Subcontractor before works begins. 3. Subcontractor work plan will show how equipment will be decontaminated. 4. Subcontractor must possess the necessary license to receive equipment in the case decontamination of Subcontractor equipment proves ineffective. If such a license can not be produced, contaminated equipment will remain in the possession of the Contractor. LOGISTICS: -Site access is available from 0700 hrs to 1630 hrs. -Temporary site access badges will be issued for duration of job to subcontract personnel. -The Contractor (BN) will provide all PPE. -The Contractor (BN) will dispose of all low-level waste generated. EQUIPMENT & SUPPLIES: Identified by Subcontractor REQUIRED TRAINING: Current OSHA 40-hour HAZWORKER Training. Rad Worker II. Hantavirus Awareness (provided by Contractor). Hazard Communication (provided by Contractor). Personnel Protective Equipment (provided by Contractor).
