The Building 991 FEVS is only effective in Rooms 133 and 13s when one <strong>of</strong> the<br />
airflow oaths specified in the above assumptions from these rooms to the north waste<br />
storage area is oresent. As long as one <strong>of</strong> the airflow Dahs to the north waste storage<br />
area is oresent, the Room 170 dock doors can be open. Therefore, operations in<br />
Rooms 134 and 13 5 are not restricted xvhsn the Room 170 dock doors are open.<br />
The restriction on storing waste contaiiiers in Building 985 and reniovjng any waste<br />
generated in Buildins 985 within 24 hours <strong>of</strong> iob completion is required to mitisate<br />
the effects <strong>of</strong> HEPA filter bypass leakage. This item was addressed in JCO-931-<br />
97.1399-hRA and is due to the fan shaft seals for the 601A and 6018 fans. For<br />
Buildiw 985 there is no material-at-risk inventory currently available to become<br />
involved in an accident that could result in ai untiltered release. This control<br />
requires that any waste generated as a result <strong>of</strong> maintenance work or filter changes<br />
must be removed from the building to an approved waste storage area within 24<br />
hours <strong>of</strong> job completion.<br />
The restriction on storing waste containers in Corridor C is based on life safety issues<br />
with the structural integrity <strong>of</strong> the corridor. This restriction is required to limit the<br />
time that personnel have to spend in the corridor. Since this restriction is based on<br />
life safety issues, storage <strong>of</strong> waste containers is also not permitted in Building 997<br />
and Building 999 since access to these buildings can only occur via Corridor C.<br />
In order to restrict non-compliant waste containers that contain liquids with hydrogen<br />
generation and vent plugging potential from the BUILDING991 COMPLEX,<br />
verification <strong>of</strong> every container brought into the facility for compliance with the<br />
requirement is specified. A waste container is considered non-compliant with this<br />
requirement if the quantity <strong>of</strong> liquids in the waste containers exceeds that normally<br />
allowed by packaging requirements (i.e., up to 1% free liquids or 4 liters for a<br />
55-gallon drum). The compliance verification can occur at time <strong>of</strong> receipt or at the<br />
container originating facility prior to shipment by examination <strong>of</strong> container<br />
paperwork. In addition, a general verification <strong>of</strong> container compliance is specified<br />
for identification <strong>of</strong> non-compliant SNM, POC, and waste containers during facility<br />
operations and tours. This latter verification is only expected to observe container<br />
locations and arrangements while personnel pass through the waste container storage<br />
area or perform activities in the facility.<br />
Container segregation means separation <strong>of</strong> the non-compliant container from other<br />
containers. The separation is expected to be five or more feet, if possible, to prevent<br />
container interaction.<br />
