ENTERGY OPERATIONS. INC.
DOCKET NO. 50-368 ARKANSAS NUCLEAR ONE. UNIT NO. 2 AMENDMENT TO FACILITY OPERATING LICENSE Amendment No. 2(M Ucense No. NPF-6 1.
The Nuclear Regulatory Commission (the Commission) has found that:
A.
The application for amendment by Entergy Operations, Inc. (the licensee) dated April 30,1998, complies with the standards and requiremenis of the Atomic Energy Act of 1954, as amended (the Act), and the Commissinn's rules and regulations set forth in 10 CFR Chapter I; B.
The facility will operate in conformity with the application, the provisions of the Act, and the rules and regulations of the Commission; C.
There is reasonable assurance (i) that the activities authorized by this amendment can be conducted without endangering the health and safety of the public, and (ii) that such activities will be conducted in compliance with the Commission's regulations; D.
The issuance of this license amendment will not be inimical to the common defense and security or to the health and safety of the public; and E.
The issuance of this amendment is in accordance with 10 CFR Part 51 of the Commission's regulations and all applicable requirements have been satisfied.

Accordingly, the license is amended by changes to the Technical Specifications as indicated in the attachment to this license amendment, and Paragraph 2.C.(2) of Facility Operating License No. NPF-6 is hereby amended to read as follows:
2.
Technical Soecifications The Technical Specifications contained in Appendix A, as revised through amendment No. 204, are hereby incorporated in the license. The licensee shall operate the facility in accordance with the Technical Specifications.
3.
The license amendment is effective as of its date of issuance to be implemented within 30 days from the date of issuance.

c.
At least once per 18 months during shutdown by:
1.
Subjecting the diesel to an inspection in accordance with j
procedures prepared in conjunction with its manufacturer's i
recommendations for this class of standby service.
2.
Verifying that the automatic sequence time delay relays are OPERABLE at their setpoint i 10+ of the elapsed time for each load block, 3.
Verifying the generator capability to reject a load of greater than or equal to its associated single largest post-accident load, and maintain voltage at 4160 1 500 volts and frequency at 60 1 3 Hz.
4.
Verifying the generator capability to reject a load of 2850 Kw without exceeding 75t of the difference between nominal speed and the overspeed trip setpoint, or 15e above nominal, whichever is lower.
5.
Simulating a loss of offsite pewer by itself, and:
a)
Verifying de-energization of the emergency busses and load shedding from the emergency busses.
b.
Verifying the diesel starts from a standby condition on the undervoltage auto-start signal, energizes the emergency busses with permanently connected loads, energizes the auto-connected shutdown loads through the time delay relays and operates for 2 5 minutes while its generator is loaded with the shutdown loads.
6.
Verifying that on a Safety Injection Actuation Signal (SIAS) actuation test signal (without loss of offsite power) the diesel generator starts on the auto-start signal and operates on standby for 2 5 minutes.

3/4 8 E!.5CTRICAL POWER SYSTEMS BASE 8 Ts 4.8.1.2.c.3 demonstrates the EDG load response characteristics and capability to reject the largest single load without areeeding predetermined voltage and frequency while maintaining a specified margin to the overspeed trip. For ANo-2, the single load for each EDG is the service Water pump, rated at 800 MP (635.9 KN).
Containment electrical penetrations and penetration conductors are protected by either de-energizing circuits not required during reactor operation or by demonstrating the OPERASILITY of primary and backup overcurrent protection circuit breakers during periodic surveillance. The eso volt air frame protective devices utilise electro-mechanical overcurrent elements which are mounted on the protective device and, in some instances, preteetive relays to trip the protective devise. Actuation of the evereurrent element or relay will trip the protective device. The molded case protective devicae utilise magnetic or thermal-magnetic overcurrent elements which are contained in the protective device. Actuation of each overcurrent element will trip the protective device.
78 3.8.2.3 Action *b" requires the performance of SR 4.8.2.3.a.1 within one hour and at least once per I hours thereafter for a loss of one of the required full capacity chargers. If any category A limit in Table 4.8-2 is not met while a charger is inoperable, the associated battery bank shall be declared inoperable and ACTION *a" entered. The category A limits in Table 4.8-2 specify the normal limits for electrolyte level, float voltage and specific gravity for each designated pilot cell. When TS 3.8.2.3 ACTION
- b" is entered without the associated battery bank being on float (i.e. charger not connected to the bus), pilot cell float voltage is determined by measuring pilot cell voltage. The tema " full capacity charger" as used in Ts 3.8.2.3 is defined as a charger that is capable of supplying an output of 2 300 amperes.
