pressure tests at Pg or within 0.25Is for peak pressure tests at P a-

2. Is of sufficient duration to establish accurately the change in leakage rate between the Type A test and the supplemental test.
3. Requires the rate that gas is inpacted into the containment or bled fror the containment during the supplemental test to be equivalent to at least 25 percent of the leakage rate mea-sured during the Type A test.

Table 4.7.1 Fbuticello Containment Penetrations (continued) + _.s d i I l Explanation of Notes: l

1. main steam isolation valves are nomclly tested by precouring the connecting volume between inboard and outboard valves. Since test pressure tends to unceat the inboard valve, a lover test pressure than Pa is specified.
2. Isolation is accomplished using manual valves in the containment supply line. Ecse valves are opened only when containment integrity is not required. 'Ibe valves are closed in accordance with valve lineup checklists which are co=pleted prior to plant heatup.

3 One-inch instrumentation lines equipped with excess flow check valves. Sub,)ect to leakage testing in accordance with Technical Gpecification h.7.D.l.b. leakage can occur only through rupture of the line or its associated instrument outside of containment.

h. TIP probes are withdrawn on a containment isolation signal and the line is isolated bj automatic closure of a ball valve. A shear valve can be manually actunted from the Control Room in the event a probe fails to retract. A solenoid valve in the purge supply line automatically closes on a contairment isolation signal.

5 Containment isolation of the CRb hydraulic control lines is accomplished with a ball check valve internal to each drive mechanism and the nomally closed hydraulic system control valve.

6. The dryvell air lock is constructed with both doors opening invan1 so that containrent pressure vill tend to seat the door seals. During overall air lock pressum tests, a st'.pport cember is installed on the inner door to prevent the door from being forced open.
7. These are internal penetmtions between the dryvell and torus.

8. Instrumentation lines not equipped with excess flow check valves. Leakage can occur only through rupture of the line or its associated instrument outside of containment. 9 This penetmtion teminates at the bottom of the suppression pool. It is not exposed to the contairment atmosphere.

10. These drains are installed at the bottom of the suppression pool.

rate ani a standby gas treatment system filter efficiency of 90% for halodems, 95% for particu-lates, and assuming the fission product release fractions' stated in TID lh8kk, the calculated maximum total whole body passing cloud dose is e. bout 3 rem and the calculated maxiusui total thyroid dose is approximately 150 rem at the low population zone distance of one mile for the j duration of the accident. The resultant doses that were calculated for the two-hour accident dose at the exclusion zone boundary of 1600 feet are lower than the above stated doses. Thus, the doses raported are the maximum that would be expected in the unlikely event of a design basis loss of coolant accident. These doses are also based on the assu=ption of no holdup in i the secondary containment resulting in a direct release of fission products from the primary containment through the filters and stack to the environs. Therefore, the specified primary g l contaiment leak rate and filter efficiency are conservative ani provide margin between

f ! i Bases Continued: l 1 Although the dose calculations suggest that the accident leak rate could be allowed to increase j to about 2.h% per day before the guideline thyroid dose value given in 10 CFR 100 would be I exceeded, establishing the test limit of 1.2% per day provides .an adequate nargin of safety to t assure the health and safety of the general public. It is ibrther considered that the allowable j leak rate should n't deviate significantly from the contalment design value to take advantage I of the design leak-tiC htness capability of the structure cv-r its service lifetime. Additional 1 margin to maintain the containment in the "as built" conditian is achieved by establishin6 the allowable operational leak rate. The operational limit is derived by multiplyirg the allowable

test leak rate by O.75, thereby providing a 25's margin to allow for leakage deterioration which may occur during the period between leak rate tests.
The surveillance testirg requirements for overnll integrated contalment leakage tests (Type A tests) and local penetration leakage tests (Type B and Type C tests) are consistent with the requirements of 10CFR50, Appendix J. " Primary Reactor Containmnt Icakare Testing for Vater-l Cooled Power Beactors."

j The leakage limitations and surveillance testing requirements placed on the containment air i lock are des 1 6 ned to provide assurance that this component is leak tight while at the same

time providing a reaccnable degree of freedom of accerc to the dryvell. The special testirg provisions specified for the air lock are consistent with the requirements of 10CFR50, Appendix J.

l 1 l Main steam isolation valves are nomally tested by preccurizing the connecting volume between the inboard and outboard valves in one steem line. The inboard =ain steam isolation valve l 1s sub jected to test pressure in 3 direction opposite to that exieting follovirg an accident. During testing, test pressure tends to unseat the valve and can lead to an invalid measuremnt. For this reason, the test pressure has been limited to 25 psi 6 for main steam isolation valve

testing and the allowable leaka6e has been stated in tems of a 25 psig test pressure.
