This restriction, in conjunction with the leakage rate limitation, will limit the site boundary radiation doses to within the limits of 10 CFR Part 100 during accident conditions.

During initial core loading and while the low power test program is being conducted and ready access to the reactor vessel is required, there will be no pressure on the system thus greatly reducing the chances of a pipe break. The reactor may be taken critical during this period; however, restrictive operating procedures will be in effect to minimize the probability of an accident occurring.

N limitations on primary containment leakage rates ensure that the total containment leakage volume will not exceed the value assumed in the accident analyses at the peak accident pressure of 49.6 peig, P a . As an added conservatism, the measured overall integrated leakass rate is '

further limited to 0.75 L, during performance of the periodic tests to account for possible degradation of the containment leakage barriers between leakage tests.

x The pressure suppression pool water provides the heat sink for the reactor primary system energy release following a postulated rupture of I the systas. N pressure suppression chamber water voltane must absorb the associated decay and structural sensible heat release during primary system blowdown from 1,035 peig. Since all of the gases in the dryvell i a l purged into the pressure suppression chamber air space during a 2oss i

. of coolant accident, the pressure resulting from isothermal compression plus the vapor pressure of the liquid must not exceed 62 pais, the suppression chamber =mwi=== pressure. The design volume of the suppression chamber (water and air) was obtained by considering that the total volume of reactor coolant to be condensed is discharged to the suppressioerchamber and that the dryvell volume is purged to the suppression chamber. ..

Using the minimum or parimum water levels given in the specification, containment pressure during the design basis accident is appravimately 49 peig, which is below the marian = of 62 peig. The maximum water level indications of -1 inch corresponds to a downconer submergence of three feet seven inches and a water volume of 127,800 cubic feet with or 128,700 cubic feet without the dryvell-suppression chamber differential pressure control. N minh== water level indication of -6.25 inches with differential pressure control and -7.25 inches without differential pressure control corresponds to a downcomer submergence of approximat.ely three feet and water voltane of appravimately 123,000 cubic feet.

radioactive materials from the containment atmosphere will be restricted l to those leakage paths and associated leak rates assumed in the accident j

break. Ths reactor may be taken critical during this period; however, l restrictive operating procedures will be in effect to minimise the

total containment leakage volue will not exceed the value asemed in the f accident analyses at the peak accident pressure of 49.6 pois, P a . As an 1

The pressure suppression chamber water volume must absorb the associated decay and structural sensible heat release during primary l system blowdown from 1,035 peig. Since all of the gases in the drywell are purged into the pressure suppression chamber air space during a loss of coolant accident, the pressure resulting from isothermal compression plus the vapor pressure of the liquid must not exceed 62 pais, the suppression chamber maxim a pressure. The design volume of the suppression chamber (water and air) was obtained by considering that the j

total voluse of reactor coolant to be condensed is discharged to the l suppression chamber and that the drywell volume is purged to the j suppression chamber.

Using the minimum or maximum water levels given in the specification, containment pressure during the design basis accident is approximately i 49 peig, which is below the marimtm of 62 pois. The maximum water level indications of -1 inch corresponds to a downcomer submergence of three feet seven inchas and a water volume of 127,800 cubic feet with or 128,700 cubic feet without the drywell-suppression chamber differential 2 pressure control. The minimum water level indication of -6.25 inches with differential pressure control and -7.25 inches without differential pressure control corresponds to a downcomer submergence of approximately

3.7 A & 4.7.A Primary Containment l : l The integrity of the primary containment and operation of the core standby cooling system in combination, ensure that the release of radioactive materials from the containment atmosphere will be restricted a

i to those leakage paths and associated leak rates assumed in the accident

analyses. This restriction, in conjunction with the leakage rate

' limitation, will limit the site boundary radiation doses to within the limits of 10 CFR Part 100 during accident conditions. l i

During initial core loading and while the low power test program is being conducted and ready access to the reactor vessel is required, there will be no pressure on the system thus greatly reducing the chances of a pipe break. The reactor may be taken critical during this period; however, l restrictive operating procedures will be in effect to ministize the '

4 probability of an accident occurring.

The limitations on primary containment leakage rates ensure that the total containment leakage volume will not exceed the value assumed in the I accident analyses at the peak accident pressure of 49.6 psig, P a. As an I added conservatism, the measured overall integrated leakage rate is further limited to 0.75 L during performance of the periodic tests to account for possible degradation of the containment leakage barriers between leakage tests.

The pressure suppression pool water provides the heat sink for the reactor primary system energy release following a postulated rupture of the system. The pressure suppression chamber water volume must absorb the associated decay and structural sensible heat release during primary system blowdown from 1,035 pais. Since all of the gases in the drywell are purged into the pressure suppression chamber air space during a loss of coolant accident, the pressure resulting from isothermal compression plus the vapor pressure of the liquid must not exceed 62 pais, the suppression chamber maximum pressure. The design volume of the suppression chamher (water and air) was obtained by considering that the total volume of reactor coolant to be condensed is discharged to the

- suppression chamber and that the drywell volume is purged to the suppression chamber.

Using the minimum or maximum water levels given in the specification, containment pressure during the design basis accident is approximately 49 pais, which is below the maximum of 62 peig. The maximum water level indications of -1 inch corresponds to a downcomer submergence of three feet seven inches and a water volume of 127,800 cubic feet with or 128,700 cubic feet without the drywell-suppression chamber differential pressure control. The ministan water level indication of -6.25 inches with differential pressure control and -7.25 inches without differential pressure control corresponds to a downcomer submergence of approximately three feet and a water volume of approximately 123,000 cubic feet.
