(3) Safety Channel trip 1

Explanation of (1) above:

Nuclear Power Plant Reactor Operator Training and NRP Staff Reactor Operator Training.

Explanation.of (2) above:

Primary Coolant flow rate trip switch (a P-E device designed to actuate wnen primary coolant flow rate = 475 gpm) functioned at 490 gpm. Small indicated fluctuations of brief duration, e.g., + 10 gpm for 100 msec, are normal in the primary' cooling system. The trip setpoint of the P-E switch had shifted in the conservative direction from 475 gpm to 490 gpm.

Exp'ana$1on.for(3)above:

l While. operating routinely at 1 Megawatt, a scram trip was generated by.the Safety Power Measuring Channel. This event had not occurred prior and has not occurred since..Every aspect of the occurrence was investigated to de-

termine the.cause and none cauld be found. Because the scram signal.was generated only by the Safety Channel, while all other power measuring systems detected no power variations, our best' diagnosis is a one-time electrical-transient,within the Safety instrumentation channel.;

. INTRODUCTION Environmental radicactivity levels in the vicinity of the North Carolina State 1

University campus have been observed to remain at.very low levels during the reporting period.

]

'2.

AIR MONITORING Tables 2.2 and 2.3 give the gross beta activities and gamma activities of selected nuclides.in units of fCi m-3 Gross beta activities are determined

by counting Millipore-air filters.. The gamma activities are reported as the composite of'five Hi-Vol glass fiber filters representing each of the moni-toring stations on campus.

-3.

MILK Monthly analyses of milk from the Campus Creamery have consistently shown concentrations of Sr-90 that are well below the maximum permissible concen-tration (Table 3.1).

Table 3.2 indicates that all samples indicate a level of I-131 that is below this laboratory's detection limit of 2.0 picocurie

' liter-1, 4.

SURFACE WATER Tables 4.1 and 4.2 give gross alpha, gross beta, and Sr-90 activities with

.the only two gamma emitters, K-40 and Cs-137, that were present in sufficient concentrations to identify. These samples were collected on Rocky Branch Creek at locations relative to the campus designated as ON and 0FF.

5.

SOIL Soil samples were collected at four campus locations (North, South, East, and West of the reactor) and also at the Old Burial Ground on Reedy Creek

. Road and at the New Burial Ground near Carter Stadium. Most samples were taken within four inches of'the surface, but some deep samples (4.5 feet) were obtained -outside the two burial sites. All samples indicated vcry low levels of radioactivity.

6.

VEGETATION Samples of grass were taken at the same locations as the soil samples.

Analysis'for gross alpha, gross beta, and specific nuclides revealed no significant levels of radioactivity..-
