S~ FSAR Question No.

240. 2 %he.Saiety Kv'aluation 'Report (Const ctien Permit Stage) states (3.4) that stoplog closures are to be prov ded to protect the entrances ta safety related structures up to e evation +22 ft. HLM. Stoplog ~

closures an the entrances of the Raa tor Auxiliary Building and the Fuel Eandling Building are shown in Figures 1.2-l3 and 1.2-16 of the FSAR. However ~ they. are not iscussed ar, described in other sections of the PSAR dealing th flood protection.

State whether the stoplogs Mill be p owdded Xf not, /ustify that they are not needed. Provide analy s of u3ve runup at all entrances bel~ elevation +22 MLS.

lf the stoplogs are to be installed, provide:

a) the bottom elevation of the door openings and the dimensions of the openings secured by the s oplogs.

b) tbe time required to place the s oplogs into position.

c) the criteria to be used to dere ine Mhen and if the stoplags are to be placed into position.

d) a discussion of the relevant tec nical specifications.

~Ree nnce Based upon PHF high vater elevation 7.2 ft mean low vater (HLV) vave runup elevation 16e0 ft KLV and plant island elevation 18.5 ft HLQ, flood protection stoplogs at entrances (Mhose aLnieum elevation is at least + L9 5 feet) safety-telated build&ops are nnt deemed necessary. Additional e runup protection is provided to the entrances of t he Fmk Handli ng Building and Reactor Auxiliary Building by the prl sence of ad5acent buildings and'tructures (see Englarged Site rPot Plan FSILR Figure 1 2-2).

Since no permanent structures are 1 ated on the south side of the Reactor Auxiliary Building, additio l vave runup protection vill be provided by installing stoplogs 4.

t SQ FSAR Question Ro,

. - 240-3 Discuss t.he hydrologic technical cification explaining (2.4.j.3) measures to be used to monitor t exf.sting beach dunes and mangrove areas ~hich are relied u n for hurricane prorection-Provided the follo~<ng inforaetio (a) the means by which storm eros a vill be measured and t: he frequency of such surveys.

(b) the means by which the aangrovI areas viLl be monitored to identify blighted areas and t frequency 'of such surveys.

~Res 0((s(.

Beach dunes and ~roves areas a not, relied upon to provide protection from hurricanes. As di cussed in Subsection2.4.5, the dunes are conservatively assumed t be eroded to an elevation of

+4 feet HIM prior to computing the maximum possible quantitica of erosion froza High~ay ALA and the p t island.. Ho credi.t is taken for the. energy dissipated or the t ee consumed in erosion of the dunes. Since the "stable base pla n elevations of W feet K.V to the east. and south of the'lant is and and elevation +5 kG.M on he north are the nat;ural ground eleva ions of. extensive flat areas, their viability is not dependent o the existence of the mangrovcs- In the Mave analysis S bsection 2.4.5, no rcductfon of mvc height or energy by the nLangr ves is assumed.

Ho FSAR change required.
