l X

The accuracy of this instrument for normal, post seismic and

~

accident. conditions will be determined ,by considering the parameters tabulated in the design input section. of this 7

l calculation.

The ' accuracy calculation for seismic (As) is bounding for all seismic events. t i

X The square root of the sum of the squares method shall.be used in this calculation for calculating: accuracy since the fact;ws affecting accuracy are independent variables, i

X Bi-directional errors and uni-directional errors will be combined '

in-a manner such that the sum of the . positive uni-directional-errors will be added to the positive portion of the bi-directional error (obtained from the square root of the-sum of.the squares ;

method), and the sum of the negative uni-directional errors will.be' added to the negative portion of the bi-directional error.- .

]

This method is conservative. Therefore, it will be used in this l calculation.

i Example: (+/-)10 = bi-directional error

+5 = first uni-directional error j

-2 = second uni-directional error i Total Error = (+10 + 5) to ( 2) = +15 to -12 .j other: #

i

- i For the purpose of this calculation, accuracy is defined as the range of ';

actual process trip value, e.g.values that may exist for a given indicated-or bistable.

an accuracy of +10 psig to -5 psig means that for an indicated or bistable trip value of 100 psig, the actual process pressure may be anywhere between 95 and 110 psig.

All l system analysis based on or using accuracy values .from this colealation should take into account the fact that operator actionn and/or automatic initiations may occur at a process value differing form '.-]

Yes Q his g" A review was made of a pertinent sessent of available literature on radiation offacts on electronic components, both from the perspective of the individus1 component and of the component assembly. Based on this review, an argument is presented that typical, nonsolected electronic componente used in nuclear plants will, with certain notable exceptions, tolerate a togal radiation dose (total 40 years integrated dose plus accidaat dese) of $110 rade or less without significar.t degradation in their performance. Conseguently, with respect to the radiation environment, the subject componente, or assemblies comprised of these componente, are in a mild environenent as defined in 10CTR50.49 (c) .

13. 1 Allowable Value (AV) - AV is defined as the analytical limit (AL) minus the difference between the Design Basis Event accuracy band (Adbe) and the normal measurable accuracy band (Anf), which does not consider calibration unmeasurables (i.e.,, waterleg errors, process errors, etc.). It is reasoned that following a/ design basis event that the output of an instrument may change by the difforence, between the normal and design basis bands. 4 4 Therefore, if the output exceeds the AV value during normal operation, the analytle.a1 limit would be exceeded if an design basis event occurs during this time (See subsection 15.7.4.1 notes 1 and 2).

AV = AL - ( Adbo - Anf) The details of the calculations for these errors are included in subsection 15. 13.2 Acceptance Band (Ab) - During calibration or calibration cheeks, the required deviation from the true value deemed acceptable without requiring readjustment. (An acceptance band shon'.d be selected such that the

In this standard, a bias error is an error that has a certain fixed value for a given instrument under specified conditions.. The exact value of the fixed error is unknown, however, the range of uncertainty is known. 13.5 Confidence true value isInterval believed - The bounds about the measured value within which the to lie. 13.6 Drift - An undesired change in the output over a period of time.

INFORMATION NOTICE No. 83-03: CALIBRATION OF LIQUID. LEVEL INSTRUMENTS Addressees: All nuclear power reactor facilities holding an operating license (OL) or construction permit (CP). (= Purcose: This information notice is provided as a notification on calibration of liquid level instruments which may have safety significance. It is expected that i r j recipients will review the information for applicability to their facilities, No specific action or response is required. Descriotion of Circumstances: I Several licensees have reported inaccurate liquid level indications from instruments on various tanks such as chemical addition tanks (CATS) or boric acid stcrage tanks (BASTS) which contain liquid chemicals or solutions with c densities different than that of water. Those instrupents that are not cali- ( brated ately. with density compensation will not measure the volume of 1.iquid accur-

E Although density compensation is a basic requirement for accurate level measurements, it is periodically overlooked. On past occasions, pure water at 60*F was used as a reference to calibrate the differential pressure trans-mitters measuring the liquid level in the _u nk r irrespective of the density difference from that of the solutions being measured.

Density corrections must be made for those liquids other than water that are contained in the tanks. The corrections must also consider the temperature of the liquid. One licensee recently determined that measuring instruments on the 4,300 gallon CAT had not been density c'bmpensated correctly for the 17 percent (by weight) solution of the sodium hydroxide in the CAT. After the density correction was factored into the measuring system, it was found that the actual volume of solution in the tank was some 300 gallons below the minimum required by technical specifications. . For

tanks.c v with e boron concentration of less than 1,000 ppm, the liquid level a - .e te .a. ' be relatively accurate because the denv " of the liquid a w ana of water will not differ significantly. However, there were .

Under these conditions, a heated tank than 100 percent full. could have overflowed when liquid level was indicating less k Compensation for differences in density and/or tempera- i r ture of liquid solutions should be included in the measuring systes during calibration. h i gNT w on2 NE8 MASTER MGf -

COMMENTS ~AND NOTES
1. Encompassed by the indication's value. .

2. For specifics see the references and the Eagle 21 Technical Manual.

3. See transfer function sheet for value.

4. Components 2 through 7 are part of'the Eagle 21 RPS System located in the auxiliary instrument room at elevation 685' and coordinate panel C-1.

5. The pressure is applied to che high pressure port of the transmitter.

6. The transmitter is calibrated separately from the other loop components.

7. Output is energized on decreasing signal for auto switchover and de-energized on decreasing signal to alarm.

8. Most stringent AV values for PAM and shall be used only if these values are more stringent than values for Westinghouse trip strings.
7 o ypice . 9. AV value for switchover is-hsf from Tech Specs and applies only to the Eagle 21 equipment (transmitter not included). Refer to references 2 and J for calculated AV values, The AV values are 10.500, i . 31 % .g;f 1/.Ay9 , 4 i 3.17M% - 4 .1 % 1 28 % Looo p/tdgntifierW -EE N tb 4R httochment No.-
