a.
Logs and Records The inspector reviewed Reactor Operation Log Book No. 4 for the period from June 1984 to April 1985.
These logs show dates and times of reactor operation, checkout sheet operation logs, pertinent reactor operational parameters, and the purpose of operation. The irradiation of materials, including the material irradiated and time and power of irradiation, were also logged. The responsible reactor supervisor signed and initialed all legs.
The inspector exanined the " Reactor Console Checkout Sheets" for checkout numbers 656 through 710.
Each set of checkout sheets included eight pages of precedural steps.
Each step was documented as verified to be performed satisfactorily.
The inspector also reviewed the maintenance log, with findings as noted in the Surveillance Activities section of this report.
No unacceptable conditions were identified.
b.
Surveillance Activities Records in the Maintenance Log and Health Physics Record Book document that the ifcensee has performed the surveillances required.
(1) Technical Specification (T.S.) 1.4 Insertion Times Once every six months, the licensee is required to verify the maxi-mum time for total insertion of regulating and shim rods to be less than 1.0 seccnd.
Surveillances were performed and results are as follows:
Regulating Rod Shim Red October 2, 1984 0.470 sec 0.460 sec
"
"
March 29, 1985 0.473 0.443 Octcber 14 ~1985 0.483 0.476 "
"
April 22,1986 0.430 0.473
"
"
All rods met T.S. requirements.
The inspector asked the licensee to trend regulating rod insertion time as it appeared to be pro-gressively increasing.
The licensee plans to repeat this surveil-lance upon completion of overhaul of the reactor pool tank.
(2) Technical Soecification J.6 The lucite hold-down rods are tc ne checked for radiation damage once a semester.
The checks, for modulus of rigidity, were performed with established procedure.
.
Tests were performed on October 12, 1984; March 29, 1985; October 14, 1985; November 4, 1985; and May 8, 1986.
Rods 55 and 44 ranged from 1.7936E+05 psi to 2.1129E+05 psi, which fell within the estab-lished criteria.
(3) Technical Specification J.4 The reactor moderator is required to be analyzed for fission product activity once per semester.
Samples were analyzed on October 8, 1984; April 10, 1985; October 17, 1985; and April 29, 1986.
No activity was detected.
6.
NRC Order on Fuel An NRC Order to Show Cause issued 9/27/85 addresses nonpower reactor fuel.
The licensee responded to the order on 11/19/85.
Review by the NRC Division of Safeguards found the licensee in compliance with the order.

Dr. Hu's RO & SRO Licenses were issued by the NRC on January 6, 1984 and June 12, 1984, respectively.
He was appointed as Chief Reactor Supervisor on Sep-tember 1, 1984 and passed requalification Examination on September 13, 1984.
In addition to the student program, on January 14-15, 1985, five senior reac-tor operator candidates from the Power Authority of the State of New York attended a two-day course of instruction conducted by Brother Kane and Dr. Augustus.
NRC Region I examined Dr. Hu and qualified him as a Senior Reactor Operator as noted in reference (e). The inspector reviewed the licensee's documenta-tion for Brother Kane, which consists of verification of reactor checkcuts and startups since the May 1984 inspection.
No deficiencies were identified.
Outstanding item 50-199/83-01-01 is therefore closed.
8.
Operatina License Renewal On August 26, 1983 the licensee requested that the Operating License for the Manhattan College nuclear facility be renewed.
Upon completion of the NRC Division of Licensing's review, Amendment No. 6 to License R-94 was granted for a twenty year renewal.
The license restates all changes and amendments made since the original license was issued on August 27, 1962.
The inspector verified that no equipment was added or additional experiments made since the last operational inspection in 1984.
No unacceptable conditions were iden-tified.
9.
Maintenance Outage The licensee entered a maintenance outage on April 25 in order to clean the reactor tank.
A slight aluminum oxide coating had appeared on the tank walls.
Measurements of tank wall thickness also were scheduled.
a.
Disposal of Pool Water and Demineralizer Resin On April 25, 1986, prior to removal of reactor coolant water and disposal of ion exchange resins, samples were taken to insure that provisions of the Radiation Safety Manual, 1983, Paragraph 6.8, were met.
Five samples of reactor coolant water and five samples of resin were tested on April 25, 1986.
The results indicated no contamination (0.005 mCf/1000 cc and 0.05 uCi/mg.) No Iodine-131 was identified.
The reactor coolant was removed from the vessel after removal of the fuel.
No de-ficiencies were identified.
b.
Removal of Fuel Elements The licensee procedure required a console checkout prior to fuel removal.
All detection instruments were activated.
Fuel elements were raised to the reactor deck and surveyed; no elements exceeded 2.5 mr/hr. The ele-ments were then stored.
The inspector verified that the storage of all
.
'
reactor fuel elements was satisfactor.
.
c.
Nondestructive Examination of Tank Walls Upon cleaning the tank, the licensee obtained ultrasonic thickness meas-urements. Original wall thicknesses were specified to be 0.200"-0.300".
No original thickness measurements were made.
Twenty-two selected areas were tested during this outage with a minimum measured thickness of O.2257".
These results indicated no significant degradation.
The test
'
points will remain on the tank for future testing.
The inspector had no further questions.
d.
Demineralizer Piping Replacement The inspector witnessed partial assembly of new domineralizer piping.
Stainless steel fittings have replaced carbon steel fittings.
This new piping was added to minimize the entry of oxides into the demineralizer.
The aluminum reactor cooling tank to stainless steel fittings interface was found satisfactory by Reactor Committee review.
e.
Procedure Update The licensee's procedures for maintenance and surveillance are not con-trolled by a single administrative document.
They vary in format, con-tent, acceptance criteria, required reviews, etc. Dicussions with the reactor administrator confirmed the need for updating the facility's procedures.
The licensee stated a review of needed revisions would be conducted in a six-month period and that revisions will be completed within a two year period.
This item will be reviewed during a subtiequent inspection.
10.
Exposure Report The inspector reviewed Quarterly Occupational Exposure and Radiation Level Surveys for 1-85 through 3-86.
The exposure from the operation of the nuclear facility is a measured value for each individual less the reading from a reference monitor badge.
All measured individual readings were less than 100 mr/yr.
The reference monitor indicated 130 mr/yr. When measurement crror is considered, the individual exposures are all equivalent to the background exposure, i
Alpha surveys of air samples showed <0.005 uC1/cf. Water sample alpha was measured at <0.005 uCi/ml, Swipes of the laboratory, lecture room, counting room, graphite facility, and ZPR source containers showed <0.005 uCi remov-able contaminants.
These results are consistent with previous reasurements.
No unacceptable conditions were identified.

Emergency Planning Emergency Planning was discussed with the Reactor Administrator.
The licensee has verified the emergency telephone numbers for the local hospital and has held fire drills.
Extraneous material was found during tours, including empty paper cartons in the lower reactor room and parts stored in the upper and lower reactor room in flammable containers.
The licensee committed to an extensive cleanup upon conclusion of the outage. The inspector had no further questions on this item.
12. Material Balance Report The inspector reviewed the Material Balance Report for R-94, SNM827 from 4-1-85 to 9-30-85.
It showed all elements and isotopes in the licensee's pos-session in quantities similar to that stated in previous reports.
The in-spector had no further questions on this item.
- 13.
Shim Rod Anomaly The inspector reviewed a rod position anomaly and associated corrective ac-tions.
On March 5, 1985, immediately after the reactor circuit breaker was closed, the Shim Rod Position Indicator showed 40% rod withdrawal.
Visual inspection revealed the rod was fully inserted.
The terminal board associated with the indicator was checked.
No malfunction was detected.
The Shim Rod was withdrawn to 100%.
Its upper limit light came on.
At that point, Shim Rod position indication was off scale.
The position indication was adjusted to provide proper indication.
No further incidents of this nature have occurred.
The inspector had no further questions on this item.
14.
E_xperiments No changes have occured in the licensee's experiments.
Discussions with the Reactor Administrator and lecture notes show that stu-dents were advised on Health Physics aspects and ALARA concerns at the start of each semester.
The inspector had no further questions.
15.
Use of Low Enrichment Fuel The NRC has amended its regulations to require licensed non power reactors to use low enriched uranium (LEU) fuel.
The licensee is conducting discussions with the Department of Energy (00E)
and attended one DOE seminar addressing costs of changing to LEU.
This will involve the folowin.
.
-- Transportation of irradiated fuel to a secure facility.
-- Manufacturing of new fuel.
-- A new Safety Evaluation.
-- A complete rewrite of all experiments.
-- A complete start-up program.
-- Retraining /requalification of reactor operators.
Submittal of estimates for the above to DOE is scheduled for the fall of 1986.
Preliminary licensee estimates are $550,000 to $650,000.
The inspector noted that licensee is on schedule for submittal of information to 00E.
16. Manaaement Meetina On May 15, 1986, an exit meeting was held with the Reactor Administrator to discuss the scope and findings of this inspection.
No proprietary information was identified as being within the inspection coverage.
