Technical Specification Internretation No. 003 Rev. 2 O

l l Because the purpose of missile shields is to protect equipment from tornado i

generated missiles, and given the fact that adequate warning is available for I tornado conditions, it is not necessary to consider protected equipment inoperable solely due to its missile shield being removed. This interpretation provides conservative pre planned allowances for control of missile shields without further consideration of equipment OPERABILITY. Removal of missile shields not contained herein, or exceeding the bounds of this interpretation require additional assessment of equipment OPERABILITV. The conservative option to declare affected equipment inoperable and compty with the provisions of Technical Specifications is always available.

l The following allowances have considered the impact on HVAC pressure i

boundaries, but do not address Security and Fire Protection requirements.

The capability to immediately re-install missile shields as used in the following allowances is deemed to exist when the necessary equipment to perform the installation is located on site and is available for use. Personnel necessary to operate the equipment shall be onsite and available when weather conditions exist such that a potential for a Tornado Watch or Warning exists. If weather conditions pose no immediate potential for adverse weather, then personnel G associated with the operation of the equipment shall be available and within 90 V minutes of the site. The shield shall also be in such condition and location to support reinstallation.

Removal and installation of missile shields shall be conducted in accordsc.ce with MDA-304, " Heavy Loads Program".

Installation of each removed shield shall begin immediately upon the associated notification (Tornado Watch, Tornado Warning, etc.) otherwise the affected system (s) shall be declared inoperable.
