Listed below is the total power gen'erated and the number of pulses performed during this year.

- 1 The reactor was taken critical 300 times.
4.
There were no facilitf changes during the year.
There was one (1) inadvertent scram. The recorder micro-5.
switch became misaligned causing it to drop off the drive wheel, causing a recorder scram.
s 6.
Major maintenance consisted of the following:
a.
Inspection and calibration of all control rods.
b.
The electric motor was replaced on one of the venti-lation system blowers.
7.
There were no non-routine experiments performed.
8.
A summary of the radioactive ef.'luent released during 1976 is as follows:

A description of the enviro = mental survey program performed

Personnel radiati'on exposures duri=g 1976 are summarized i
as follows:
l Radiation exposures to reactor and health physics a.
person =e1 averaged 12. 3 milliroentgens per individual per week.
b.
Radiation exposures to reactor visitors averaged 2.47 milliroentgens per individual per day.
l No personnel over-exposures occurred during this period l
c.
of reactor operation.
11.
Reactor Surveys:
Significant radiation levels in the-reactor facility were a.
documented in the following areas:
~
(1)
The shielded door to the dry exposure room 'is I
monitored whenever it is opened. In 1976, theie were 240 such openings - with an average radiation level of 20.4 milliroentgens per hour per opening, and a maximum level for the year of 200 milliroentgens per hour.
(2)
The maximum ' recorded level in a restricted area
{where visitors are normally not allowed without staff i,
_f.g
.. supervision) was 1.3 roentgens per hour. This occurred
~N
~
on the reactor deck during the brief transfer operation of an in-core experiment. Non-staff, noness,ential
. personnel are not allowed in the vicinity during such operations mal. 1,
