Of fice of Nuclear Reactor Regulation November 16, 1979 Page 2 design at the Kewaunee Plant requires that the SFP system be continuously run.

Even though the charcoal filter units are normally bypassed, conservative interpretation of the existing wording in Tech Specs requires both above described tests to be performed af ter 720 hours0.00833 days <br />0.2 hours <br />0.00119 weeks <br />2.7396e-4 months <br /> of system operation. Revised wording identical to the above accepted wording is being submitted in order to eliminate these highly expensive, unnecessary tests.

Revised wording is being submitted to remove the monthly testing requirement of a full load rejection test of the diesel generators and establish a test frequency of once per 18 months. This f requency is in accordance with accepted practice at recently licensed plants. Reduced load rejection frequency has also been recommended by the diesel generator manufacturer. We therefore request immediate review and relief from this requirement in light of the NRC Staff's concern for placing unnecessary challenges upon safeguard equipment, without justifiable cause.

Amendment No. 29 to the Kewaunee Technical Specifications changed the previous pressurizer pressure coincident with level safety inj ection signal to a pressure only signal. The bases of Section 3.5 was overlooked in requesting the change.

Ravised wording is being submitted to make the bases coasistent with the previous change.

Enclosed is a check in the amount of $1200.0C in order to cover the fee associated with processing this amendment. We have determined this amendment to be a Class II amendment in accordance with 10 CFR 170.22.

. Basis Instrumentation has been provided to q nse accident conditions and to '

initiate operation of the engineered safety features.(1) Section 2.3 of these specifications describes the limiting safety system settings for the I-protective instrumentation. ,

Safety Injection The Safety Injection System is actuated automatically to provide emergency cooling and reduction of reactivity in the event of a loss-of-coolant accident or a steam line break accident.

Safety injection is initiated upon occurrence of low 41 pressure in the pressurizer, which would occur following depressurization and coolant loss in a loss-of-coolant accident, and directly by a high containment pressure signal.

Safety injection in response to a steam line break is provided directly by a low steam line pressure signal, backed up by the coincidence signal from the pressurizer and, in the case of a break viithin the containment, by the high containment pressure signal.

The Safety injection of highly borated water will offset the temperature-induced reactivity addition that could otherwise result from cooldown following a steam line break.

4.6 PERIODlC TESTING OF EMERGENCY POWER SYSTDI Applicability

/

Applies to periodic testing and surveillance requirements of the emergency power system.

Obj ect ive To verify that the emergency power sources and equipment are operable.

Specification

.

The following tests and surveillance shall be performed:

a. Diesel Generators

2. Automatic start of each diesel generator, load shedding, and restoration to operation of particular vital equipment, all initiated by a simulated loss of all normal a-c station service power supplies together with a simulated safety injection signal. This test will be conducted at each refueling interval to assure that each diesel generator will start and assume required loads to the extent possible within one minute. During this test a checkout of emergency lighting will be performed.
