Wire-mesh doors are alto provided for radiation protection (access control) as required. Where other considerations, such as HVAC integrity, require that a hollow metal door be closr:d, and venting is still required the door is modified in such a way as to allow it to release during a tornado. These doors are also restrained during release to prevent destruction of the door.

Seismic Category I structures are designed.to withstand the impact 42 loads from the spectrum of tornado generated missiles as~shown.in Table 3.5.8.
Structures are of sufficient thickness to prevent perforation or the generation of secondary missiles by tornado generated missiles to which they can be exposed.
Non-Seismic Category I structures.or structural components'whose 42 failure under tornado' loading could possibly impair the function of Seismic Category I structures, equipment, systems or components are' designed to withstand the effects of the tornado loading to the extent
'that the functional requirements of Seismic Category I structures, equipment, systems and components are not impaired.
3.3.2.3 Method of Analysis
' The dynamic wind pressure, q, is calculated from the following equatien:
q - 0.00256 V2 where:
q - wind pressure [ psf ]
y - wind velocity [ sph ]
0130.1 The tornado wind velocity is not assumed to vary with height above the ground. The tornado wind pressure is applied as a static load. The O.'
pressure distribution and shape coefficients for tornado loadings are the same as the coefficients used for wind, as described in Subsection 3.3.1.2.

'A'ttachment to TXX-89622 Page 9 of 18 3.3 Wind and Tornado Loadinas 3.3.1 Wind Desip Criteria All Cate p.ry.I structures exposed to wind forces are designed to withstand the effects of the design wind. The design wind specified has a velocity of 80 mph r,t 30 ft.above ground, based on a recurrence interval of 100 years.
The procedures that are used to transform the wind velocity into pressure loadings on structures and the associated vertical distribution of wind pressures and pust factors are in accordance with pru:edures presented in Paper No. 3269 of tie American Society of Civil Engineers (ASCE) (" Wind Forces on Structures"),
and these procedures are acceptable to the staff.
The procedures that are used to detamine the loadings on seismic Category I structures induced by the desip wind specified for the plant are acceptable because these procedures provide a conservative basis for engineering design to ensure that the structure will withstand such environmental forces.
The use of these procedures provides reasonable assurance that,ismic in the event of design-bests winds, the structural integrity of the plant se ry I structures will not be impaired and, consequently, seismic Catepry I sys and cesponents located within these structures are tely protected and i
will perfom their intended safety functions, if Confomance with.
4 these precedures is an acceptable basis for satisfying, in part, the requirements of @C t.
3.3.2 Tornado Design criteria
)
All Category I structures exposed to tornede forces and needed for the safe shutdeun of the plant are designed to resist a.tormede of 300 mph tangential wind velocity and have been analyzed to show that,ther can resist the additional 50 eph transnational wind velocity, according to staff requirement. A simulta-neous atmospheric pressure drop uns assmed to be 3 get in 3 sec. Tornado missiles are aise censidered in the desige, as discussed in Section 3.5 of this report.
The pr'ocedores that are used'to trensfore the tornede wind velocity into pressure leadings are steilar;te those used for the dosip wind loadings as discussed in Section 3.3.1.' The tornede-eissile effects will be determined by using precedures discusand in Section 3.5.3..' The total effect of the design tornede en ebogery I structures is determined by appropriate combinations of the indiriggsi effects of the tornado wind pressure, pressure drop, and tornado j
associated mealles.
Nonseismic Category I structures or structural components whose failure under tornado loadings could possibly impair the function of seismic Ca ry I structures equipment, systems, or components are designed to withs the effects of,tornede loading to.the extent that the functional requirements of seismic Category I structures, equipment, systems, and components are not lapeired. Nonseismic Category I equipment that can possibly become a tornado-generated missile is evaluated as a potential missile.

, The Category I structures that feature openings to allow venting of these structures during the tornado are designed with missile shields over these openings capablo of providing the same missile protection as the alls and roofs of the respective structures.
The procedures used to determine the loadings on structures induced by the design-basis tornado.specified for the plant are acceptable because these procedures provide a conservative basis for engineering design to ensure that the structures withstand such environmental forces.
The use'of these procedures provides reasonable assurance that, in the event of a design-basis tornado, the structural integrity of the plant structures that have been designed for tornado loads will not be impaired, and, consequently, safety related systems and components located within these structures will be adequately protected and may be expected to perfom necessary safety functions as required.
Conformance with these procedures is an acceptable basis for satisfying, in part, the requirements of GOC 2.
3.4 Water Level (Flood) Desian 3.4.1 Water Level (Flood) Design To ensure conformance with the requirements of GDC 2 with respect to protection against flooding, the staff reviewed the overall plant flood protection design, including all systems and components whose failure as a result of flooding could prevent safe shutdown of the piant or result in uncontrolled release of significant radioactivity. The applicant has provided protection from inuniation and static and dynamic effects for safety-related structures, systans, and components by the " dry site" method (defined in Regulatory Guide 1.102) as described below.
The calculated probable maximum flood level (PE) for the facility is eleva-tion 789.7 ft (see Section 2.4.3).
Althou intake structure are below this elevation,gh portione of the service water the safety-related service water pump motors, valve operators and controls are above the maximum flood level.
There is essential equipment in the safeguards building below the maximum flood i
- level, tiowever, the grade elevation for the safeguards building is 810.0 ft; no doors or entries to the safeguards building are located below the maximum flood level. Water stops are used in all construction joints below grade, and safety grade sump pumps are provided f6r the safeguards building.. The lowest elevations of the auxiliary building.and fuel bei ding are above the maximum flood level. JThe only area of concern regarding exterior flooding involves the safety ct$17ed-weter system pumps and condensers, located at elevation 778 ft of the electrical and control building. At the central section at this elevation, thelre is direct access from the e actrical and control building to the turbine building. Although there are no doorways between the certral section of this elevation and the safety chilled-water equipment compartments, flood water could enter the compartments through nonweter-tight seals and open floor drain lines which communicate with the drain sump in the central section of the electrical and control building.
One path for flood water into the turbine building could be through the circulating water system pipe tunnel, l
which is open to the turbine bu'1 ding at elevation 758 ft 6 in. Also, as l
discussed in Section 10.4.5 of this repor.t. the access between the turbine 3-5 I
