i Applicability -
Applies to the reactor building purge air treatment system and its associated filters.
Objective To specify minimum availability and efficiency for the reactor building purge air treatment system and its associated filters.
Specification 3.15.2.1 Except as specified in Specification 3.15.2.3 below, the Reactor Building Purge Air Treatment System filter AH-F1 and fans AH-E7A and B shall be operable as defined by the Specification below at all times when, containment in:egrity is required.
3.14.2.2*
a.
The results of the in-place DOP and hclogenated hydrocarbon tests at maximu='available flows on HEPA filters and charcoal adsorber banks for AH-F1 shall show <0.05% DOP penetration and
<0.05% halogenated hydrocarbon penetration, except that the DOP test will be conducted with prefilters installed.
b.
The results of laboratory carbon sample analysis from the reactor building purge syste: filter carbon shall show 290%
radioactive methly iodide decontamination efficiercy when tested at 2500F, 95% R.H.
- c.- Fans AH-E7I and B shall each be shown to operate within I 2,500 CFM of design flow (25,000 CFM).
3.15.2.3 a.
Fro: and af ter the date that the filter AH-F1 in the reactor building purge system is made or found to be inoperable as defined by Specification 3.15.2.2 above, or both f ans AH-E7A and B are found to be inoperable, reactor operation is permissible only during the succeeding 30 days, unless such filter and at least one fan is sooner made operable.
b.
If the required conditions for the reactor building purge filter and f an cannot be met af ter 30 days, operations shall be terminated innediately and the reactor placed in cold shutdown within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.
- Not required until criticality for cycle 5 operation.
Bases The Reactor Building Purge Exhaust Syste= filter AH-F1 while normally used to filter al) reactor building exhaust air, serves also as the post-accident purge filter when used in conjunction with 'the Hydrogen Purge System to reduce hydrogen gas concentrations in the reactor building following a LOCA.
It is
- necessary to demonstrate operability of these filters to assure readiness for service is required, approximately thrity (30) days following a hypothetical i
LOCA.
