Linda Gundrum, NRC Project Manager for Point Deach Nuclear Plant From:

Tom Malanowski, Licensing Senior Project Engineer, Point Beach Nuclear Plant Subjoct: 'l3CR 191 Clarifications Please be advised of an error in our letter NPI A7-0466 which supplemented Technical Spcification Change Request 191. In that supplement we explairuxi that Unit 2 Refbcling Outage 23 (U2R23) would be the first Unit 2 refuehng to provide an operating cycle ofgreater than 12 months. Subsoquently, wo have reviewed the Refueling Outage Plan (dated 8/12/97) and discovered that U2R24 will be the first Unit 2 refueling to provide an operating cycle of greater than 12 months. Therefore, we request that the pending amendment change all reference to "U2R23"to "U2R24" ne markups of the revised Techrdcal Speci0 cation pages are attached As stated in our letter NPL-97-0466, the irnplememation schedule does not involve a significant hanrd, authorize a significant change in the types or total amounts of any efEuent release, or result in any significant increase in individual or cumulatin occupational exposure.

We regret any inconvenience this revision nuy have cauwd.

If you have any questions, please call me at (414) 221 3950.

During power operation, the requirements of 15.3.2 8 and C may be modmed to allow the following components to be inoperable for a specified tirne, if the system is not restored to meet the requirements of 15.3.2-8 or C within the time period spoolfled, the appropriate remotor(s), except as otherwise noted, shall be placed in the hot shutdown condition within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and borated to a shutdown margin equivalent of et least 1.0% delts Wk at cold shutdown, no xenori condl6ans.

y The chemical arW volume cxmtrol system provides control of the reactor coolant system boron inventory. This is normally accomplished by using one or more charging pumps in series with one of the two boric acid transfer pumps. Above cold shutdown conditions, a minimum of two boron (njection flow paths are required per unit to ineurs functional capablity in the event that an essumed single acove failure renders one of the flow paths inoperable.

1 The boration volume evallable through any flow path is sufficient to provide the required shutdown margin at cold shutoown. Xenon free conditions from any expected operati.N condition. The volume requirement is assoolates with boration from just critical, hot zorn or l

pi full power, peak xenon with control rods at the insertion lima, to xenon-free, cold shutdown tel l

with the highest worth control red assembly fully withdrawn. This requires approximately

• 26,600 ganons of 2700 ppm boreted water 90m the raft'eling water storage tank (RWST) or l the concentrations and volumes of borated water speelflod in Table 15.3.21 from the boric acid storage tanks (BASTS).

These RWST perameters are in effect following U1R25 for Unit 1 and U2R2/for Unit 2; and take effect prior to leaving the co'd shutdown condition of those outages.

Prior to U1R25. the Unt 1 rninimum RWST volume and boren concentrabon values for this basis statement are 24,100 gallons and 2000 ppm respectively. Pdor to U2R23, the Unit 2 minimum RWST volume and bomn concentration values for this basis statement are 24,100 gallons and 2000 ppm respecthely.
