The provisions of Surveillance Requirement 3.0.2 do not apply to the test frequencies specified in the Containment Leakage Rate Testing Program. However, test frequencies specified in this Program may be extended consistent with the guidance provided in NEI 94-01, "Industry Guideline For Implementing Performance-Based Option Of 10CFR 50, Appendix J," as endorsed by Regulatory Guide 1.163. Specifically, NEI 94-01 has these provisions for test frequencies extension:
1.
Consistent with standard scheduling practices for Technical Specifications Required Surveillances, intervals for recommended Type A testing may be extended by up to 15 months. This option should be used only in cases where refueling schedules have been changed to accommodate other factors.
2.
Consistent with standard scheduling practices for Technical Specifications Required Surveillances, intervals for the recommended surveillance frequency for Type B and Type C testing may be extended by up to 25 percent of the test interval, not to exceed 15 months.
The provisions of Surveillance Requirement 3.0.3 are applicable to the Containment Leakage Rate Testing Program.
5.5.2.16 Control Room Envelope Habitability Program l
l A Control Room Envelope (CRE) Habitability Program shall be l
established and implemented to ensure that CRE habitability is l
maintained such that, with an OPERABLE Control Room Emergency Air l
Cleanup System (CREACUS), CRE occupants can control the reactor l
safely under normal conditions and maintain it in a safe condition l
following a radiological event, hazardous chemical release, or a l
smoke challenge. The program shall ensure that adequate radiation l
protection is provided to permit access and occupancy of the CRE l
under design basis accident (DBA) conditions without personnel l
receiving radiation exposures in excess of 5 rem total effective l
dose equivalent (TEDE) for the duration of the accident. The l
program shall include the following elements:
l l
a.
The definition of the CRE and the CRE boundary.
l l
b.
Requirements for maintaining the CRE boundary in its l
design condition including configuration control and l
preventive maintenance.

Appropriate application of ASTM E-741 shall include l
the ability to take minor exceptions to the test l
methodology. These exceptions shall be documented in l

Measurement, at designated locations, of the CRE pressure l
relative to all external areas adjacent to the CRE l
boundary during the pressurization mode of operation by l
one train of the CREACUS, operating at the flow rate l
required by the VFTP, at a Frequency of 24 months on a l
STAGGERED TEST BASIS. The results shall be trended and l
used as part of the 24 month assessment of the CRE l
boundary.
l l
e.
The quantitative limits on unfiltered air inleakage into l
the CRE. These limits shall be stated in a manner to l
allow direct comparison to the unfiltered air inleakage l
measured by the testing described in paragraph c. The l
unfiltered air inleakage limit for radiological l
challenges is the inleakage flow rate assumed in the l
licensing basis analyses of DBA consequences. Unfiltered l
air inleakage limits for hazardous chemicals must ensure l
that exposure of CRE occupants to these hazards will be l
within the assumptions in the licensing basis.
