Project No.8-9025.00 Date: 5/28/90 Page 3 of 12 The objective of this calculation is to determine the ambient temperature rise in the TDAPYV pump area of the Intermediate Building during a 4 hour SBO-induced loss of ventilation. Because the Ginna Station Blackout coping duration is 4 hours, the simplified methodology provided in NUMARC 87-00, Section 7 will be applied.The Section 7 methodology is based on the fact poured concrete walls act as heat sinks and that their surface temperatures will remain essentially constant over the course of the 4 hour loss of ventilation. As stated in the previous section, the surface temperature of the solid concrete block walls will also be assumed to remain constant.Section 7 of NUMARC 87-00 presents the following simplified equation for use in evaluatin'g a four hour loss of ventilation: Tait-Tw+[QIA]3~4 where: Tair is the resultant ambient air temperature in the TDAPV pump area(the north portion of el.253'-3" of the Intermediate Building}after 4 hours;Tw is the wall temperature; Q is the heat generation rate fthm hot piping, equipment, and electrical devices;and A is the surface area of the walls and ceiling acting as heat sinks.The effects of opening doors to allow removal of heat through natural circulation are evaluated as defined in Section 7, p.7-15, of NUMARC 87-00: Tair-Tw+(Q3~4l[A3~"+16.18 F 0 6 3]}where F is the"door factor" and is equal to H3<W;where H and W are the height and width of the door, respectively.

The following steps shall be performed to accomplish the described method for determining the TDAFW pump an:a ambient temperature: 1.Sum the wall surface areas to obtain A in square meters.For conservatism, the surface ama of the ceiling will be neglected as it is constructed of corrugated metal attached to the pouted concrete floor slab of the elevation above.2.Determine the initial wall temperature. The effects of the higher temperature of the south waH which is exposed on its outer surface to the Containment Structure ambient temperatuie will be considered. 3.Conservatively estimate the heat generation rate, Q, in the TDAFW pump area.This will be done by considering heat rejected by hot piping and equipment using the equations given on p.7-19 of NUMARC 87-00.Heat rejected by operating electrical equipment will also be considered. 4.Apply the results of the above and calculate the resultant ambient temperature. 5.Evaluate the effects of opening doors.Step 1: Sum wall surface areas to obtain A, in sq.meters This step is accomplished using the referenced drawing, 33013-2113. As previously identified in the Assumptions Section, the solid'concrete block walls bordering the North, East, and West sides of the Intermediate building will be considered in this evaluation. The South wall borders the Containment Structure and is constructed from poured concrete.The ceiling surface area has been neglected as a heat sink since it consists of corrugated metal.

Project No.8-9025.00 Date;5/28/90 Page 7 of 12 Step 2: Determine the initial wall temperature, T;in'C The initial wall temperature will be calculated by means of a weighted average of Surface area between the South wall, adjacent to the Containment Structure and all other walls, The initial temperature of all other walls is assumed to be 104'F, which is the stated FSAR value for the normal maximum ambient temperature in the Intermediate Building.The South wall surface temperature is calculated as an average between the Containment maximum normal ambient of 120'F and the 104'F Intermediate Building ambient temperature, Therefore, T (South wall)=(120'F+104'F)/2=112'F the initial temperature computed by weighted average on the basis of area is: Ti=(33.33/97.93)*112 +(64.6/97.93)

Review of Table 2 shows that the uninsulated Tb.exhaust lines were considered to have a surface temperature of 240'F.This value is based upon the information in the AFW Steam Turbine Bill of Materials, previously referenced, which gives exit steam conditions. In addition to the 62,105 watts generated by hot piping and equipment, an additional 1,000 watts will be added to account for heat generated by emergency lighting, operating solenoids, etc.Therefore, the total heat generated in the TDAPV pump atea is: Q=62,105+1,000=63,105 watts Step 4: Calculate the ambient temperature This step is accomplished by applying the NUMARC 87-00 correlation: Tair=Ti+[Q/A]T-=41.7+[63,105/741.33]3/4 =41.7+28=697 C=1575 OF Step 5: Evaluate the effect of opening doors This step is performed using the NUMARC 87-00 correlation for considering free convection through vertical openings.Arrangement drawing 33013-2121 shows double doors on the west side of the North wall which open to the Turbine Bldg.The'Turbine bldg area adjacent to these doors is assumed to remain at 104'F during the 4 hour blackout duration due to its configuration and the lack of significant heat sources in the area.The effects of opening doors to allow removal of heat through natural circulation are evaluated as defined in Section 7, p.7-15, of NUMARC 87-00: Tair-Tw+(Q3/4/[A3/4 +16.18 F 0 8653))where; Devonrue Calculation

Conclusion Break flow decreases from 6.6 lbs/sec.(63 gpm)to 3.45 lbs/sec.at 4 hr.following changes in RCS pressure.Voiding appears in the upper head and upper plenum.The voids are condensed in the SG.Natural circulation flow is never lost.Voiding in the upper head is approximately 50.5%by volume after 4 hr.Voiding in the upper plenum is approximately 46.5%by volume after 4 hr.aWa~l74 II2288.8 2888.8 c 1688.8 M Vl'V L N IN9,8 0.Pfp]~lt 1488.8 1289.8 fi fjo<1898.8 2888.6 4668.8 666B.S 866B.S TIIK (SEC)ISSGG.S 12669.9 14668.8 IQS,S 118e.e PKSTNS----PKSTNm<2)1888.8 iI II we.e I'g I Illi 1848.8 I I 1828.8 M I I 1688.8 I I I 968.8 I i I 968.8 948.8 928.8 2668.8 46ee.e 6689.8 6888.8 TI%<SEC)STATIOH ELNXOUT 12866.8 14668.8
