.s PLANT SYSTEMS SURVEILLANCE REQUIREMENTS 4.7.6.1 The control room emergency ventilation system shall be demon-strated OPERABLE:
a.
At least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> by verifying that the control room air temperature is < 120*F.
b.
At least once per 31 days by initiating flow through each HEPA filter and charcoal adsorber train and verifying that each train operates for at least 15 minutes.
c.
At least once per 18 months or (1) after any structural maintenance on the HEPA filter or charcoal adsorber housing, or (2) following painting, fire or chemical release in any ventilation zone comunicating with the system by:
1.
Verifying that the charcoal adsorbers remove > 99% of a halogenated hydrocarbon refrigerant test gas Een they are tested in-place in accordance with ANSI N510-1975 while operating the ventilation system at a flow rate of 2000 cfm + 10%.
2.
Verifying that the HEPA filter banks remove > 99% of the D0P when they are tested in-place in accordance with ANSI N510-1975 while operating the ventilation system at a flow rate of 2000 cfm + 10%.
3.
Verifying within 31 days after removal that a laboratory analysis of a carbon sample from either at least one test canister or at least two carbon samples removed from one of the charcoal adsorbers demonstrates a removal efficiency of > 90% for radioactive methyl iodide when the sample is tested in accordance with ANSI N510-1975 (130*C, 95%
R.H.).
The carbon samples not obtained from test canisters
~
shall be prepared by either:
a)
Emptying one entire bed from a removed adsorber e.
tray, mixing the adsorbent thoroughly, and obtaining samples at least two inches in diameter and with a length equal to the thickness of the bed, or b)
Emptying a longitudinal sample from an adsorber tray, mixing the adsorbent thoroughly, and obtaining samples at least two inches in diameter and with a length equal to the thickness of the bed.
