D. L. Ziemann letter to c. Reed dated January 16, 1979

Dear Mr. Ziemann:

Our Staff has reviewed the draft evaluations prepared for SEP Topics IV-1.A, Operation with Less than all Loops in Service; V-10.A, Residual Heat Removal System Heat Exchanger Tube Failures; and VIII-3.A, Station Battery Test Requirements which were transmitted by References (a) and (b).

We have confirmed that the technical information presented in the draft evaluations for Topics IV-1.A and V-10.A is correct for both Dresden Units 1 and 2.

Our review of the draft evaluation for TopicVIII-3.A indicates that your conclusions may have been drawn upon in-complete information.

The battery.test requirements are included in the station technical specifications, however, we do not feel that these specifications give a complete picture of the tests which are performed.

For your use and information, we are enclosing copies of the battery test procedures used by station personnel.

We feel that your evaluation of the pro-cedures will give a more comi;>lete analysis of our station O \\

operations.

2

Do not smoke or light flames in battery storage areas.

Hydrogen may be given off b't batteries whic:h can ex-plode when exposed to fire.

When filling batteri~~ with water, avoid spilli~g water on top of cells.

If water is spilled, wipe it up so cells do not short.

3.

All specific gravity readings are to be t~~perature corrected using attachment B.

4.

Do not under any circ~mstances let.any metal lay across the battery terminals.

The battery will short and an explosion will most likely occ~r.

If readings are taken while batteries are en equalize, note it on data sheet.

Nominal specific gravity is 1.215 at 77°F. specific gravity ~ay range+.010 points at 77°F w*ith electrolyte level at high level line and stTll be considered satisfactory.

With float voltage set between 2.17 V and 2.19 V per cell, and no greater than a 5°F variation in cell temperature of a series string

{step o; tier of rack)., the individual cell voltages can vary frc~ each other+.03 volts per cell.

When taking spedfic gravity readings, corrections must be made for var-iatfons in temperature of the electro_lyte.

For each 3°F (1.6i°C) in temperature cf the electrolyte above i7eF (25°C) add one point (.OOI) in specific gravity to the cbse;ved hydro~;~~~ rea:in;s; and fc* each J°F(l.67°C) in temperature below 77°F (25°C) subtract one (.001) in specific gravity from the observed hydro~eter reading.

STATION BATTERY CAPACITY TEST DOS 6900-2 Revision 2 January 1978 A.

PURPOSE

The purpose of the test is to verify that the battery capacity is equal to or greater than 85% ~f the manufacturers rating.

The test is to consist of an eight hour rated discharge for the 24/48V, i2SV and 250V batteries.

PRECAUTIONS D.O.S.R.

I.

If any of the individual cells approach 1.75 volts during the test, the test is to be temporarily stopped, noting the time.

The cell is to be removed from the circuit and re-placed with jumpers.

The test is then to be continued, noting the re-start time *.

Be sure to consider the duration the test is stopped in the total time of the test.

1.

Battery is to be declared inoperable if capacity is found to be less than 85% and appropriate action is to be taken per Tech. Spec. 3.9.

If battery capacity is between 85% and 100%,

is to be notified as to corrective action to the vendor be taken.

The battery, however, is sti 11 operable.

Give the battery an equalizing charge following DOP 6900-1, OOP 6900-2, or DOP 6900-3.

Isolate the battery charger from the battery following OOP 6900-8.

Record cell voltages, specific gravities, and temperatures on the data sheet.

Have maintenance connect the test load per DMP 541.

CLOSE the test breaker and begin the discharge. Refer to DHP 541 for o~eration of test load box.

R~cord the time and dis-charge current.

1

The fol lowing criteria must be met for water returned from 02/3 Radwaste to.condensate storage:

Turbidity - 20 or less APHA Turbidity Units or 1 ppm or less Filterable Solids Conductivity - Less than 1.0 umho Gross Activity - 8.0 x 105 uuCi/1 or less Silica - !. 0.30 ppm pH - 6.0 to 9.0 Chloride - !. 0.10 ppm

2.

Laboratory Criteria for Turbidity.

a.

If the APHA turbidity is 20 or less, a filterable solids test is not required.

If all other chemistry criteria is met, the water is acceptable for storage.

b.

If the APHA turbidity is between 20 and 50, a filterable solids test is required.

If the filterable sol ids test

. results are 1 ppm or less and all other chemistry criteria are met, the water is acceptable fdr storage.

PRECAUTfONS

1.

Cells that approach zero voltage prior to the end of the test must be shorted out to prevent them from going into reversa 1 *

2.

Do not smoke or light a fire as explosive hydrogen could be present.

E.

LIMITATIONS AND ACTIONS

1.

Variation in specific gravity should not exceed 15 points and the average specific gr~vity should not be less than 1190.

If the specific gravities do not fall within these limits, the acid should be adjusted in the low reading cells and the corresponding specific gravities recorded.

~"*-..._...

F.

PROCEDURE 1 *. Give the battery a thorough equalizing ~harge.

2.

At the end of the charge, record all temperatures, voltages, and specific gravities on the data sheet.

CAUTION Variation in specific gravities should not exceed 15 points and no cell should have a gravity less than 1190.

If gravities do not fall within these limits; acid should be added to the low reading cells as specified in Section 11.g of the Exide Battery Manual and the adjuste~ gravity recorded.

a.

Place both chargers in service and balance loads.

b.

OPEN battery feed breakers to bus 1 and 2.

c.

CLOSE TEST switch and adjust load to 93.6 - 94.0 amps.

4.

After 15 minutes, record the voltage of each cell.

Extremely weak cells will begin to show at this time.

s.

~-4: One hour after the start of the test, record the battery voltage, voltage of each cell, and the discharge current; continue to record them each hour.

CAUTION If a cell indicates that it is approaching 1.50 volts, begin more frequent readin'1S on that cel 1.

Cells that approach zero voltage must be jumpered out to prevent *them from going into reversal.

Record the exact time.any cell goes 1.0 volts and* the exact time any cell is jumpered out.

If

.. cells are shorted out, calculate a new final terminal
