. 4.2 ACCESS CONTROL
/
The test objective is to verify that controls and alarms necessary for proper regulations of access to potentially contaminated areas in the area defined by the interim ABSCE function as designed. Proper operation of locks, latches, and alarms for doors associated with Unit 1 equipment and/or contained within or are part of the interim ABSCE boundary shall be considered acceptable test results.
5.0 PREREnUISITES That portion of Unit 1, and all equipment associated with the interim ABSCE, must be completed prior to this test. All components (ducting, filters, flow control dampers, etc.) associated with the Auxiliary Building Gas Treatment System must he completed. Installation and coerability of building isolation dampers, general supply fans, and general exhaust fans must be assured. All penetrations of the interim ABSCE must be installed and properly sealed. Power and control circuitry must be operational for the ABGTS and associated dampers, instrumentation, and alarms. Control air must be available for pneumatically operated dampers.
Access control doors, locks, and other system components must be installed and operational. Power must be supplied to card-key readers, local alarms, Main Control Room alarms, and indicator lights.
6.0 LNVIRONMENTAL CONDITIONS The test may be conducted at ambient conditions. Wind direction and velocity, ambient temperature, relative humidity, and outside harometric
\. pressure shall be recorded during the test.
J fr {}gg;r
2 In particular. the test portion which concerns the AHGTS will: (a) Verify the startup and control capabilities of the system, connidoring a single operating component failure. (b) Verify the capability to reach (within a specified time) and maintain the required negative pressure within the interim ABSCE defined for use during period betwecn Unit 1 startup and Unit 2 startup. For the extent of this area see the temporary drawings marked ABSCE Series. (c) Verify the efficiency and proper operation of the components and instrumentation in the air cleanup unit. - The portion of the test related to the access control system will verify proper operation of locks, latches, and alarm annunciation for types 3, A B, and C safety-related doors that are associated with Unit 1 equipment and/or contained . within or are part of the interim Auxiliary Building Secondary Contcinment Enclosure boundary. 4.0 OBJECTIVES AND ACCEPTANCE CRITERIA 4.1 AUXILIARY BUILDING GAS TREATMEhT SYSTEM The test objective is to determine that the ABGTS has the capabilities necessary to reduce the concentration of radioactive nuclides in air releases from within the interim ABSCE to the environs during accidents to levels sufficiently low to keep the site boundary dose rate below the 10CFR100 guideline value. It must also minimize the spreading of airborne radioactivity within the Auxiliary Building following an accidental release in the fuel handling and waste packaging areas. Individual system requirements needed to accomplish these objectives and the acceptance criteria for each requirement are listed in Table I.

PREOPERATIONAL TEST INSTRUCTION TVA-9A AUXILIARY BliILDING GA3 TREATMENT SYSTEM AND AFCESS CONTROL SYSTEM Test Description The Auxiliary Building Gas Treatment System to be tested consists of the ABGTS filter assemblies, heaters, fans, dampers, and interim ABSCE_as getailed by EN_ PES in the drawings attached in Appendix H. The ventilation system is bounded by the interf ace with the normal Auxiliary Building exhaust system on its supply side and continues to the Shield Building exhaust vent. This test will verify the capability of the ABGTS to function properly during accident conditions for which it was designed. In particular, the startup and control of the system, considering a single operating component f ailure will be verified, the capability to reach and maintain the required negative pressure within the intorim ABSCE will be verified, and the ef ficiency and proper operation of the components and instrumentation in the ai. cleanup unit will also be verified. The Access Control System to be tested consists of all type 3. A, B, and C safety related doors that are associated with Unit 1 equipment and/or enatained within or are part of the interim ABSCE. This part of the tect
- celated to the access control systet will verify proper operation of locks, latches, and alarm annunciation.
The completed test data package will become part of the plant historical records.

J. ENCLOSURE 3 CLARIFICATION OF DESIGN REQUIREMENTS AND PREOP TEST RESULTS
- 1. Background The interim ABSCE boundaries were defined and operations during the interim period were discussed in the enclosures to the March 29, 1976, memo to NRC. As stated in that writeup, operation of the ABGTS is not changed by utilization of the interim ABSCE. ABGTS operation is described in FSAR Section 6.2.3.
- 2. Testing Proper operation of the ABGTS and isolation of the interim ABSCE are verified during the preop testing program. In particular, the capability of the ABGTS to establish and maintain the required negative pressure within the interim ABSCE is verified. Infiltration to the interim ABSCE at the negative pressure is shown to be no greater than that value stated in Section 6.2 of the FSAR. In addition, it is also shown that redundant low-leakage dampers installed at the boundaries of the interim ABSCE close automatically to isolate the interim ABSCE upon receipt of an accident signal.
Test results to this date have shown that the required negative pressure can be established and maintained in the isolated interim ABSCE. However, infiltration rates have exceeded the acceptance criterion. TVA personnel are presently in the process of identifying and sealing leakage paths. The test results package will not be approved until the acceptance criterion is met.
- 3. Seismic Criteria Isolation dampers and associated controls installed in the interim boundary are safety grade and seismically qualified. These dampers and controls interface with the previously installed two-unit ABSCE isolation damper controls which are also seismically qualified. Doors and hatch covers added to complete the interim boundary have not been seismically qualified.
The short duration of the interim period between unit 1 completion and unit 2 completion coupled with the relatively small chance of a significant seismic occurrence during that period did not warrant the qualification of these doors.
- 4. Passage of Construction Material and Personnel Two temporary roll-up doors have been installed in series at the entrance to the unit 2 containment to provide an interim boundary and also allow passage of construction materials. All heavy construction has been completed in unit 2 containment; thus it is expected that construction materials shipped through the doors will generally be small and easily moved. In addition, two personnel doors have been installed in parallel with the roll-up doors. These allow passage ,
of personnel and hand-held materials without opening the roll-up doors. The series nature of the door installation ensures that at least one door will be closed except during passage of material, such as . - . insulation, when its size requires that both doors be open simultan eously. g'
Construction material which must be moved into the lower floors of the auxiliary building must pass through the main hatch at the 734 elevation. A temporary hatch cover has been installed at this hatch to provide an interim boundary. This hatch cover will remain closed except during passage of construction materials. Upon initiation of an evacuation alarm, closure of the doors or hatch cover used for passage of materials will be the responsibility of employees stationed at the doors while open, who will be specifically charged with the duty of door closure upon alarm or after use for materials passage.
- 5. Single Failure Redundant, series dampers are installed in all ducts penetrating the interim ABSCE. Doors in the boundary are either installed two-in-series of if a single door has been used, the doors are locked closed and under administrative control. In the closed position, these door,s are considered to be passive components.
