10 CFR 50.59. Report.
REF:
License R-57 1.
The following report is submitted for the period January 1,1987 to December 31, 1987 in accordance with Paragraph 50.59, Title 10, code of Federal Regulations.
2.
During the above period there were no changes in performance characteristics or tests which require inclusion in the annual report, however, the following changes in facility design and operating procedures were made after approval of the Reactor Safeguards Committee:
a.
Facility Design:
(1) During the period May 21 to July 9, 1987, the reactor was shut down so that asbestos could be removed from the ceiling of the room and an automatic sprinkler system could be installed.
(2) The automatic sprinkler system is a dry system that operates in the following manner using a Simplex 4001 fire alarm control.
a)
The piping in the reactor room is dry until either temperature sensing heads in the ceiling reach 135'F or a manual lever is actuated after breaking the glass on the alarm box.
b)
'n' hen the system is filled with water, a claxon sounds but the sprinklers will not open until their heat sensing device reaches 165'F.
c)
The unit also has a sensing device that will sound an alarm if the system inadvertently leaks and fills with water.
l b.
Standing Operating Procedures:
See attached changes.
[
t c.
Emergency Procedures:
See attached changes.
i 3.
The quarterly fuel element surveilance tests indicate that the inspected elements were in good condition.

U.S. Nuclear Regulatory Conmission 4.
The energy generated by the reactor during the reporting period was as follows:
January 1987 2,009.69 KW hours February 1,580.43 March 1,440.18 April 1,533.83 May 816.84 June Shut down July 1,588.37 August 1,771.96 September 2,151.07 October 1,435.67 November 1,306.17 December 1,895.22 17,559.43 KW hours 5.
During the report period there were two unscheduled shut downs.
Both were caused by a dirty slide wire and one of the two was also caused by a broken roller on the log pen holder.
6.
Maintenance problems and the corrective maintenance performed were as follows:
a.
Linear recorder reading not coinciding with log recorder l
reading -- replaced calibration battery; b.
Noisy start-up channel -- replaced electrolytic capacitors in power supply and transistors in pulse amplifier; c.
Linear recorder sluggish during calibration -- replaced tube in amplifier; d.
Dim eye tube in solu-bridge conductivity meter -- replaced vacuum tubes and 4 fd capacitor; Noisy and sticking recorder pens -- cleaned slide wire and e.
replaced slide wire wipers and rollers; f.
Blown heat exchanger in water cooling system -- replaced heat exchanger.
7.
Summary of radioactive effluents released or discharged beyond the effective control of the license:
a.
Liquid -- none; b.
Airborn -- less than 0.1 Ci; c.
Solid -- none.
3.
U.S. Nuclear Regulatory Commission 8.
The reactor continues to be used as a neutron source for neutron activation analysis of biological samples and for hot atom chemistry research.
In addition the reactor is also now being used for training Fort Calhoun Power Reactor Operators.

June 10, 1987 Changes to Standard Operating Procedures 2.11 Reactor Start-Up Change Record in los approximately every hour the following data...
Record the following data in the log af ter start-up, to:
af ter any significant change, at intervals not to exceed four hours, and before shut-down.
i ~
Justification:
In operation, the safety rod is always up, and the shim rod is normally never moved af ter the reactor is at power.
Operation since 1959 has shown that the reg rod changes position very little during an operating day.
4-E 1 d)
Dele te :
When the dose rate reaches 50mr/hr, the "Radector" l
alarm bell will ring.
Justifiestion:
The Radector is no longer is use.
t 12-4 d)
Change:
All personnel will monitor their hands, clothing and soles of their shoes before leaving the reactor
- area, to:
Personnel will follow good radiological practices when working with radiosotopes and carefully monitor their hands, clothing and soles of their shoes upon leaving the reactor room.
Jus tifica tion:
The way the original statement is written 0mplies that even if personnel are not working with radiosotopes they must monitor themselves before l
1eaving the area, i

- E Changes to Emergency Plan 7.2.2.1.1 Change from: Calibrated recording constant air monitor is in 24-hour (Pg. 8) operation in the Reactor Laboratory to:
Calibrated recording constant air monitor will be operated while the reactor is in operation and will be available for 24-hour operation if necessary.
Justification:
Since there will be no airborne radiation escaping while the reactor is not operating, shutting of f the air pump will prolong the life of the pump.
7.4.5.1.1 and 8.5.2.1.6 (Pgs.11 and 14)
Change from:
Scott Air Pak to:
Self Contained Breathing Apparatus (SCBA)
Justification:
This will eliminate reference to a brand name.
8.5.4 Change from:
The portable health physics instruments and dosimeters (Pg. 14) in the emergency cart will be inspected and checked for operability quarterly and calibrated semiannually, to:
T he...... and calibrated annually.
Justification: This will make the calibration frequency coincide with the annual calibration of all the other laboratory survey seters, i
10.1.1.6 Delete:
Energency on site personnel vill be initially trained (Pg. 15) and biennially retrained in "How to use a Scott Air Pak."
Justification:
Personnel sill not have to use a Self Contained Breathing Apparatus.
l 8.3.3 Change from: Telephones are available throughout the hospital including on the reactor console....
to: Telephones.... including near the reactor console.
Justification: Keeping the telephone on the reactor console makes too much clutter on the desk.
The cord is of succificent length to reach the console but, under normal conditions, the telephone vill be kept on a table behind the console.
