PLANT SYSTEMS SURVEILLANCE REQUIREMENTS (Continued)'
- 3)
Verifying that the system maintains the control room envelope at a positive pressure of greater than or equal to 1/8 inch Water Gauge at less than or equal to a pressurization flow of 2000 cfm relative to adjacent areas during system operation (1); and I
- 4)
Verifying that the makeup filter unit heaters dissipate 4.5 +
0.45 kW when tested in accordance with ANSI N51 0-1980.
- f.
After each complete or partial replacement of a HEPA filter bank, by verifying that the HEPA filter bank satisfies the In-place penetration and bypass leakage testing acceptance criteria of less than 0.05% in accordance with ANSI N510-1980 for a DOP test aerosol while operating the system at a flow rate of 6000 cfm +/- 10% for the cleanup units and 1000 cfm +/- 10% for the makeup units; and
- g.
After each complete or partial replacement of a charcoal adsorber bank, by verifying that the charcoal adsorber bank satisfies the in-place penetration and bypass leakage testing acceptance criteria of less than 0.10% in accordance with ANSI N51 0-1980 for a halogenated hydrocarbon refrigerant test gas while operating the system at a flow rate of 6000 cfm +/- 10% for the cleanup units and 1000 cfm +/-10% for the makeup units.
(1) Measured points at a positive pressure but less than 1/8 inch Water Gauge are acceptable if an evaluation, considering appropriate compensatory action, demonstrates that the condition meets the requirements of GDC-1 9. The provisions of this note expire at 0800 on September 19, 2005.
