NONCONSERVATIVE OPERATOR MANUAL ACTIONS IDENTIFIED IN APPENDIX R ANALYSIS

"Preliminary Westinghouse transient analysis calculations of Watts Bar Nuclear (WBN) Unit 1 fire protection features revealed that there is less time than previously credited to perform certain operator manual actions (OMA) to prevent Pressurizer (PZR) overfill during an Appendix R fire.

"Specifically, an assumed Appendix R fire in rooms 713.0-A28, 737.0-A1A, 757.0-A2, 757.0-A5, 757.0-A9, 772.0-A1, 772.0-A2, or 772.0-A5 could result in spurious operation of multiple components in the normal and emergency charging flow paths. Westinghouse's analysis indicates the required time to isolate the normal charging path is approximately two minutes, securing the second charging pump is approximately four minutes and isolating the emergency charging path is approximately 12.5 minutes.

"Based on this preliminary analysis, WBN procedures are non-conservative since they require these actions to be completed in 18 minutes.

"TVA has verified that potentially impacted Appendix R equipment remains functional; however, a compensatory fire watch has been established for the above listed areas. This immediate action will ensure that the approved Appendix R Fire Safe Shutdown Plan can be achieved."

The licensee has notified the NRC Resident Inspector.

DRYWELL TO TORUS VACUUM BREAKER FAILURE DURING SURVEILLANCE TESTING

"While cycling AO-2382A (TORUS-DW VAC BREAKER) for required surveillance testing, [the vacuum breaker] did not indicate fully closed on all available indicators. The procedure for this condition was utilized to continue to cycle the vacuum breaker to achieve closed indication on all available indicators. The vacuum breaker was cycled a total of four (4) times and dual indications were present for approximately six (6) minutes. During the six (6) minutes that the vacuum breaker indications did not show fully closed, the Technical Specification Limiting Condition for Operation (TS LCO) requirement was not met. The Monticello Safety Analysis assumes all eight (B) vacuum breakers are closed, therefore this condition is being reported per 10CFR50.72(b)(3)(ii)(B) and per 10CFR50.72(b){3)(v)(D). The vacuum breakers are all capable of performing their design function and all safety related equipment is operable."

The NRC Resident Inspector has been notified.

The same vacuum breaker failed its surveillance test in a similar fashion on February 7, 2014 (See EN #49808). The surveillance test for this vacuum breaker is due again on February 18, 2014.

AGREEMENT STATE REPORT - LOST MEDICAL PACKAGE

The following information was received via email:

"On February 11, 2014, the RSO of Eisenhower Medical Center, LN2425-33, contacted [the California Department of Health, Radiologic Health Branch] RHB about a Bracco CardioGen Rb-82/Sr-82 generator that was packaged for shipment to the manufacturer for disposal. The package was left unattended/unsecured in an unrestricted area on February 10, 2013 between 1600 PST and 1800 PST awaiting [common carrier] pickup . The package was sealed with radioactive material labels. When the first technician arrived at the facility at approximately 0600 [PST], the box was missing and no paperwork from [the common carrier] had been left. [The common carrier] was contacted and they had no records of a pick-up. [The common carrier] has initiated an investigation.

"The licensee reported the following information for the package:
"Surface dose rate 19.4 mR/hr and 1 meter dose rate 323 microR/hr;
"Surface wipe 713 dpm/100cm2; and
"Total mCi 99.9 (3.60 GBq).

"On February 12, 2014, the RSO contacted RHB and stated that someone from housekeeping placed the package in the dumpster which was picked up on February 11 and sent to the Riverside County Landfill. The landfill and Riverside County HAZMAT were informed. The licensee personnel then proceeded to the landfill to attempt to recover the package. The package has not been recovered as of this time."

California Report #: 021114

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
