Qualified per IEEE Std 323-1974 and IEEE Std 344-1975, as stated in Rosemount Report D8400102.

Radiation

Accuracy within ±(1.5% of upper range limit + 1.0% of span) during and after exposure to 55 megarads TID gamma radiation at the centerline at the following dose rate: 2 megarads/hr for 2 hr,

1.5 megarad/hr for 4 hr, 1 megarad/hr up to

55 megarads TID and an additional 55 megarads TID at a rate of 1 megarad/hr during post-accident operation

Range Code 0: ±(2.25% of upper range limit + 1.0% of span)

Seismic

Accuracy within ±0.5% of upper range limit after a seismic disturbance defined by a required response spectrum with a ZPA of 7 g

Range Code 0: ±0.75% of upper range limit

Steam Pressure/Temperature

Accuracy within ±(2.5% upper range limit + 0.5% of span) during and after sequential exposure to steam at the following temperatures and pressures, concurrent with chemical spray for the first 24 hr:

420 °F (215.6 °C), 50 psig for 3 minutes

350 °F (176.6 °C), 110 psig for 7 minutes

320 °F (160.0 °C), 75 psig for 8 hours

265 °F (129.4 °C), 24 psig for 56 hours

Range Code 0: ±(3.75% of upper range limit + 0.5% of span)

Chemical Spray

Composition is 0.28 molar boric acid, 0.064 molar sodium thiosulfate, and sodium hydroxide to make an initial pH of 11.0 and a subsequent pH ranging from 8.5 to 11.0. Chemical spray is sprayed at a rate of

0.25 gal/min/ft2.
