'fhe battery shall be a

125 volt, 60 cell iron;clad or lead-calcium pasted plate type.

The jars shall be of heat-resistant, shock-absorbing transparent plastic of uniform thickness.

High and low electrolyte level lines shall be permanently marked on all four sides of the jars.

Ample sediment space shall be provided.

Cells shall be vented and provided, with permanent leakproof concealed 1

plastic cover with bayonet type vent plug so constructed as to allow escape of gases but preclude the escape of electrolyte spray.

Attention: Mr. B; Place

Subject:

Millstone 81 Battery

Dear Mr. Place:

The attached sheet shows the calculations used to determine the battery size necessary to meet your specified duty cycle load profile.

The actual ampere hour drain seen by the bat'.ery during the 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> duty cycle is 1207 AH. An LCU-17 type battery, with an 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> capacity rating of 1200 ampere hours, would almost satisfy this energy, requirement if discharged at its 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> rate of 150 amperes.

However; the non-)inepr nature of the duty cycle. with high current drain during the first hour period will be the determinuig criterion for sizing the battery.

A larger battery such as an LCU-21 with an 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> rating of 1500 ampere hours 'would easily satisfy the first hour energy requirements (excluding the initial 2 second load of 2987 amperes) with capacity to spare for the,

balance of the 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> period.

Even this size cell, however, would not sup-ply the initial inrush current surge of 2987 amperes for 2 seconds.

To satisfy this load an even larger cell, an LCU-27 with an 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> capacity of 1950 ampere hours, is required.'. Thus the 2 second load requirement is the factor that determines the actual battery size.

It will, of course, be capable of maintaining the final seven hour energy requirement for an

'xtended period of time, up to '17 additional hours.

Attached also are two copies of the cell voltage and plate potential readings taken on the subject batterics o>> 10-19-72.

They indicate all cells to be in a normal healthy condition.

~If you have further questions relative to the Millstone 81 battery, please do not hesitate to call nie.

Very truly. yours,
