DOCKETS 50-266 AND 50-301 TESTING OF THE NEW EMERGENCY DIESEL GENERATORS POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2 In response to the NRC staff reviewers' questions pertaining to testing of the diesel generators for the Point' Beach Nuclear Plant Diesel Generator Addition Project, we are providing the following information which outlines the tests that are being, or have been, conducted on the diesel generators. The outline also-contains approximate times when future tests will be performed. -

Factory Accentance Testina Factory acceptance testing was successfull'y completed during December of 1993 on both~of the emergency diesel generators:

.1. Performance tests per paragraphs 6.2.1.2a through 6.2.1.2d of IEEE Std 387-1984

2. Single-Load Rejection-Test equal to our largest single load

3. Full-Load Rejection Test

4. Transient Tests 0 - 25% Load Step  :

f. 0 - 50%- Load Step  ;

O - 75% Load Step j 0.- 100% Load Step l 3.002$ , t ,

The following testing was completed on one of the emergency diesel generators:

1. Start and Load Acceptance Tests consisting of 30 consecutive successful start and load tests

2. Load Acceptance Test (Load Profile Test)

3. Margin Test per the IEEE Standard 387-1984 ,

4. 24-Hour Endurance Test 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at 2987 kW and 22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> at ,

2951 kW, rated load is 2850 kW .}

Site Accentance Testina Site acceptance testing will be performed in two phases. The:first -

phase will consist of the tests shown below and will be' performed prior to permanent tie-in to the plant. The tests will be ,

performed by using a temporary connection to the electrical i distribution system.

1. Start Tests (25 starts per unit) ,

i

2. Load-Run Test ,

l'

3. Fast-Start Test

4. Hot Restart Test These tests are scheduled to be conducted during August.and -

September of 1994. 1 The second phase of testing will be conducted during the tie-in phase of'each diesel. These tie-ins will be performed ~during the  :

refueling outages for.each unit.  !

7. Combined SIAS and LOOP Test. This test will be only run as an "

SIAS coincident with a LOOP. A delayed SIAS or LOOP scenario.

will not be conducted. This is consistent the current testing .

process for existing emergency diesel generators.  !

'The projected schedule for these tests is as follows:

October 1994 EDG G-04 to Unit 2, B Train (2A-06)

April 1995 EDG G-03 to Unit 1, B Train (1A-06) and EDG G-04 to Unit 1, B Train (1A-06)

October 1995 EDG G-03 to Unit 2, B Train (2A-06) and EDG G-02 to Unit 2, A Train (2A-05)

April 1996 EDG G-02 to Unit 1, A Train (1A-05)

A Technical Specification amendment request to allow the use of the new emergency diesel generators is being prepared for submittal.

We expect to submit the request during the second quarter of 1994.

Approval of_the. Technical Specification amendment request will be necessary by September 1994 to allow the tie-ins to begin in October 1994 as scheduled. Therefore, observation of the tie-in testing by the NRC Technical Staff will not be possible prior to issuance of the Technical Specification amendment.

Please contact us if there are any questions.
