Interim Storage of Spent Nuclear Fuel (ISSF) is an installation for temporarily storing spent nuclear fuels. Nuclear fuel storage pools must be free from contamination by corrosion-causing microorganisms such as Sulphate Reduction Bacteria (SRB). This research aims to detect SRB on the pool’s wall, floor, and spent nuclear fuel racks. The measured parameters consisted of physicochemical, total bacteria, total SRB, and detection of SRB on the wall, floor, and spent fuel rack in the pool using the SRB kit. The results showed that the quality of the water chemistry in the pool was within limits according to the provisions of the International Atomic Energy Agency, except for the total bacteria (> 1000 CFU/ml). In the water pools around the racks of spent fuels, SRB was also detected at 30 CFU/ml, while the level of SRB on the walls, floors, and spent nuclear fuel racks showed varied values from moderate to severe. This research is important especially to identify corrosion-causing microbes for water and biofilm samples. This is the first step in understanding the problem of biofilm formation and contamination of microorganisms in spent fuel storage pools.

“…In elevated temperatures, Mei et al (2022) noted a dominance of planktonic microalgae over the denser species (e.g., diatoms) due to the reduction of light intensity at the deeper water column. Green microalgae such as Chlorella are competitive species and have the ability to dominate especially in favorable conditions (Sugoro et al, 2022). Furthermore, the relatively high wind speed and mixing during the second and third sampling dates (4.3 m/s and 4.7 m/s, respectively) promoted the dominance of diatoms.…”

Developing countries such as the Philippines suffer from a lack of policy development and implementation on wastewater treatment and discharge. Chlorella vulgaris is a microscopic green algae that has been employed in other countries for WWT due to its ability to simultaneously reduce pollutants and produce valuable biomass. However, challenges in technology adaptation such as differential efficiency depending on the location and wastewater types were encountered. Three liquid wastes of different origins—municipal (public market), agricultural (piggery effluent), and industrial (meat processing plant) wastewaters, were used to gauge the remediation potentials of C. vulgaris in a simple photobioreactor setup. Treated samples from municipal, agricultural, and industrial wastewaters showed microalgal growth rates of 0.2685, 0.1527, and 0.1809, respectively, along the 6-day treatment period. Post-intervention comparisons of treated vs. untreated samples revealed a lower electrical conductivity, total dissolved solids, chemical oxygen demand, nutrients (nitrate, ammonia, phosphate), and fecal coliform (MPN/100 mL) on treated samples. Moreover, all treated samples demonstrated relatively higher dissolved oxygen concentrations, denoting the photosynthetic activity by the microalgae. Therefore, Chlorella vulgaris could be harnessed for the remediation of different wastewaters in Nagcarlan, Laguna, Philippines to circumvent issues in water reclamation and degradation.

“…Microorganisms are cosmopolite organisms which can live in various places on earth [1], including in extreme environments, such as heavy metal contaminated environments [2] or high radiation exposure [3]. Microorganisms living in high radiation environments are known to have phenotypically sophisticated characters, as well as molecular repair mechanisms that can prolong their survival under extreme radiation [4].…”

Bacteria which are living in extreme environment have potential for bioprospection as candidates for drug discovery and bioremediation. Radiation-resistant bacteria can be obtained from environments that have radiation sources. Pool water containing radioactive material is one of the important components in the Iradiator Gamma Karet Alam (IRKA) facility. Research on the presence of bacterial communities in the IRKA cooling pool water has never been conducted. This study was conducted to determine the bacterial community of IRKA cooling pool water using Nanopore Sequencing. The study identified 7 phyla, with Proteobacteria and Firmicutes as the dominant with 95.9 and 3.9%, respectively. Phreatobacter, specifically P. oligotrophus, emerged as the dominant genus and the most prevalent species, constituting 71.22% of the cooling pool water samples at the IRKA facility. The limited number of studies conducted on these dominant species presents an opportunity for further exploration of their potential benefits.
